1.1 Introduction to Clock over IP With the development of IP networks, IP transport is applied to most communications networks. The IP network, however, is an asynchronous transport network. The equipment on an IP network fails to extract timing signals from the physical links. Therefore, a new way of clock acquisition is required for the network equipment.

As a low-cost IP clock solution, clock over IP serves mainly the base stations that do not require strict time synchronization. These base stations can be the NodeB or Access Point (AP) in a Wideband Code Division Multiple Access (WCDMA) network, the Access Point in a UMTS Broadband (uBro) or the Base Transceiver Station (BTS) in a Global System for Mobile communications (GSM) network.

Clock over IP is implemented by the IP clock server and IP clock client. The IP clock server obtains timing signals from a clock device, such as a Global Positioning System (GPS) or Building Integrated Timing Supply System (BITS) device. After local phase lock and hold, the server transmits IP packets through an IP network to the IP clock client, that is, a NodeB or an AP in a WCDMA network, an AP in an uBro network or a BTS in a GSM network. In this way, the server provides the client with a synchronization clock that has the hold characteristics.

1.2 Introduction to the IPCLK1000 1.2.1 Position of the IPCLK1000 in the Network

The IPCLK1000 is developed by Huawei. It mainly acts as the IP clock server for IP transport in a WCDMA or GSM network. The IPCLK1000 provides a clock for the base stations to which clock sources are unavailable. The introduction of the IPCLK1000 does not affect the architecture of the network.

This section takes the IPCLK1000 in a WCDMA network for example. Figure 1-1 shows the position of the IPCLK1000 in the WCDMA network.

IPCLK1000

When some equipment in an IP network is unable to extract timing IP packets, the IPCLK1000 can also serve as the IP clock client on that equipment side.

Unless otherwise stated, this document assumes that the IPCLK1000 acts as the IP clock server.

1.2.2 Features of the IPCLK1000 The IPCLK1000 has the following features:

Supports multiple clock source inputs. Provides clock source outputs for other devices. Supports multiple clock source switching methods. Sends IP packets as scheduled to IP clock clients for time synchronization. Is able to act as the IP clock client as required. Supports Operation and Maintenance (OM) on the Local Maintenance Terminal (LMT)

or M2000.

1.3 Timing Signal Processing 1.3.1 Input and Output of Timing Signals

Clock Source Input The IPCLK1000 supports the following types of clock source:

BITS clock



External 8 kHz clock, which is a standard 8 kHz clock provided by an external device External 1 Pulse Per Second (PPS) clock GPS or Global Navigation Satellite System (GLONASS) clock

The IPCLK1000 can use its built-in satellite card to obtain synchronization timing signals.

The BITS clock is categorized into the following types:

Two 2.048 MHz or 1.544 MHz unbalanced clock inputs Two 2.048 Mbit/s or 1.544 Mbit/s unbalanced clock inputs Two 2.048 MHz or 1.544 MHz balanced clock inputs Two 2.048 Mbit/s or 1.544 Mbit/s balanced clock inputs

Timing Signal Output The IPCLK1000 can provide lower-level devices with timing signals whose frequency variation is less than ±50 parts per billion (ppb). The output clock can be configured to be 10 MHz or 2.048 MHz.

In addition, for easy recognition of whether the 2.048 Mbit/s or 1.544 Mbit/s clock source is compatible with the IPCLK1000, the 2.048 Mbit/s or 1.544 Mbit/s timing signals can be converted into 2.048 MHz or 1.544 MHz timing signals inside the IPCLK1000. The converted timing signals are further exported to the output ports, so as to facilitate verification of the clock sources.

1.3.2 Switching Between Clock Sources After clock sources are set, the IPCLK1000 can use one clock source as the current clock source input. The IPCLK1000 supports three modes for clock source switching: free, manual, and auto.

Free: The IPCLK1000 uses the free-run timing signals generated by the internal oscillator as the clock source input.

Manual: The input timing signals at a specific port is manually set to be the clock source input.

Auto: Based on the priorities of the clock sources, the IPCLK1000 automatically selects the timing signals imported to a specific port as the clock source input. If the clock source is faulty, the IPCLK1000 then automatically switches to the clock source that takes priority over any other available clock source.

1.3.3 Working Principles of the IPCLK1000 as an IP Clock Client The IPCLK1000 can be configured to be an IP clock client and serve the device that is incapable of the IP packet resolution functionality.

Acting as the IP clock client, the IPCLK1000 resolves the timing packets sent from the IP clock server, restores timing signals from the packets, and then provides the timing signals for the associated device such as a base station.

1.3.4 Clock Synchronization Acting as an IP clock server, the IPCLK1000 sends timing IP packets to IP clock clients before the clients resolve the IP packets and restore timing signals.



An IPCLK1000 can send timing packets to a maximum of 10,000 clients at 1, 10, 20, 30, 40, or 50 packets per second. The rate is configurable. 50 packets per second is recommended. The timing packets sent to one client occupy a bandwidth not higher than 50 kbit/s.

The following consoles are available for the OM of the IPCLK1000:

LMT The LMT is applicable to local and remote maintenance. It is used to maintain a single IPCLK1000 from aspects such as software upgrade, data loading, alarm data collection, and equipment maintenance.

M2000 The M2000 is applicable to remote maintenance. It is used to maintain multiple IPCLK1000s from aspects such as software upgrade, data loading, alarm data collection, and equipment maintenance.



Local maintenance: refers to the OM process where a user logs in to the IPCLK1000 by directly

connecting an LMT to the local Ethernet port on the IPCLK1000. Remote maintenance: refers to the OM process where a user in an equipment room or at a network

maintenance center configures IP routes on the LMT or M2000 to log in to the IPCLK1000 remotely.

1.4.2 Introduction to OM Functions The IPCLK1000 provides the following main OM functions:

Security Management Configuration Management Software Management Fault Management Log Management

1.4.3 Security Management For security management, the IPCLK1000 can protect the operator information by automatically locking the LMT application if no operation is performed during a period of time.

1.4.4 Configuration Management Configuration management is mainly applied to equipment maintenance and data configuration. For configuration management, the IPCLK1000 performs consistency check on configuration data.

Two data configuration modes are available. They are dynamic data configuration and static data configuration. In dynamic data configuration mode, the modified data takes effect immediately. In static data configuration mode, the modified data takes effect only after the IPCLK1000 is reset.

The following commands are applicable only to static data configuration:

SET SYSWORKMODE SET CLIENTMODE SET ETHIP

All the other commands are applicable to dynamic data configuration.

1.4.5 Software Management For software management, the IPCLK1000 has functions such as software version management and software upgrade. You can query the software for its version. You can also upgrade the non-compliant versions to compliant versions.

1.4.6 Fault Management The alarm management system detects and reports information about faults in real time. The LMT or M2000 then displays the alarm information and provides appropriate handling suggestions.



1.4.7 Log Management The IPCLK1000 records the information about operations in real time and saves the records as operation logs to facilitate fault identification and troubleshooting.

The IPCLK1000 has relatively low security guarantee. To enhance the security and reliability of the IPCLK1000 that accesses a network, you need to configure an external firewall.

Layer 3 Private Network The IPCLK1000 provides timing services for NodeBs, as shown in Figure 1-3.

Connections between the NodeBs and the IPCLK1000 After convergence at the switches or other equipment, the NodeBs are connected to the RNC over the leased layer 3 private network.



The IPCLK1000 is installed on the RNC side. It provides timing services for the NodeBs through its service FE port or GE optical ports.

Connections between the OM equipment and the IPCLK1000 The LMT and M2000 perform OM for the IPCLK1000 through the OM FE port on the IPCLK1000.

Figure 1-3 Layer 3 private network

Layer 2 Private Network The IPCLK1000 provides timing services for NodeBs, as shown in Figure 1-4.

Connections between the NodeBs and the IPCLK1000 The NodeBs are connected to the IPCLK1000 through layer 2 devices. The elements in the whole network are divided by VLANs. The NodeBs and the IPCLK1000 are grouped in the same VLAN. After convergence at the switches or other layer 2 equipment, the NodeBs are connected to the RNC over the leased layer 2 private network. The IPCLK1000 is installed on the RNC side. It provides timing services for the NodeBs through its service FE port or GE optical ports.

Connections between the OM equipment and the IPCLK1000 The LMT and M2000 perform OM for the IPCLK1000 through the OM FE port on the IPCLK1000.



VLANs are not necessarily configured in a layer 2 private network. The purpose of setting VLANs

is to enhance security. If VLANs are applied to the network, the IPCLK1000 and the NodeBs must be grouped in the same

VLAN.

The space for storing version files of the IPCLK1000 is divided into an active workspace and a standby workspace. The workspaces store different versions of files.

The active/standby relationship is relative. It is subject to the active software. The workspace that stores the active software is called the active workspace, and the other one is the standby workspace.

Prerequisites The FTP server works properly. It is located in the same intranet as the IPCLK1000. The

two communicate properly. No firewall exists between the FTP server and the IPCLK1000. The specified user name and password for login to the FTP server are correct. In addition,

you have the right to read the specified directories.

Procedure Step 1 On the MML client, run the DLD SOFTWARE command to download the required host

software to the standby workspace on the IPCLK1000.

You must enter the IP address of the FTP server, user name and password and specify the save path.

Step 2 On the MML client, run the ACT SOFTWARE command to switch the standby workspace to active and activate the downloaded software.

After the host software is activated, the IPCLK1000 is automatically started.

Step 3 Disconnect the LMT from the IPCLK1000 and exit the LMT application.

Step 4 On the LMT PC, install the LMT application associated with the new host software of the IPCLK1000.

For details, refer to section 3.4.3 "Installing the LMT Application."

Step 5 Restart the LMT application and log in to the IPCLK1000.

Step 6 On the MML client, run the LST SOFTWARE command to check the version information of the host software.

The new host software is expected to be active.



The IPCLK1000 does not support version rollback. Therefore, before you upgrade the software, run the ULD CFGFILE command to back up the data files.

----End

3.6 Reconfiguring the IPCLK1000 3.6.1 Data to Be Reconfigured on Site

The data of the IPCLK1000 is initially configured before delivery. Therefore, you need to only reconfigure the related data on site, based on the field data as described in section 3.2.3 "Planning Data." This section describes major data reconfiguration tasks.

3.6.2 Changing the Service IP Address of the IPCLK1000 If the service IP address set before the delivery of the IPCLK1000 does not comply with the network planning result, you should change that IP address to the planned IP address.

To change the service IP address of the IPCLK1000, perform the following steps:

Step 1 On the MML client, run the SET ETHIP command, and set the port type to service to change the service IP address.

Step 2 (Optional; required when the IPCLK1000 and the IP clock client are located on different network segments) On the MML client, run the ADD IPRT command to configure a route for the service port, through which the IPCLK1000 is connected to the IP clock client.

After you run the SET ETHIP command, you need to reset the IPCLK1000 to validate the configuration.

----End

Step 2 can be moved into the procedure for interconnecting the IPCLK1000 and the IP clock client.

3.6.3 Setting the Working Mode of the IPCLK1000 The IPCLK1000 supports two working modes: server and client. The default setting is the server mode.

To set the working mode of the IPCLK1000, perform the following steps:

Step 1 On the MML client, run the LST SYSWORKMODE command to check the setting of the working mode.



If the result and the planning are… Then...

Consistent, This task ends.

Inconsistent, Go to Step 2.

Step 2 On the MML client, run the SET SYSWORKMODE command to set the working mode to the planned mode.

After you run the SET SYSWORKMODE command, you need to reset the IPCLK1000 to validate the configuration.

----End

If the working mode of the IPCLK1000 is set to Client, the procedures described in sections 3.6.4 "Reconfiguring Clock Sources", 3.6.5 "Changing the Clock Source Switching Mode", and 3.6.6 "Reconfiguring the GPS Data" do not have to be planned or performed.

3.6.4 Reconfiguring Clock Sources The clock source information is the information about clock input to the IPCLK1000. One IPCLK1000 can be configured with multiple clock sources at a time. You should configure clock sources as planned.

To reconfigure clock sources, perform the following steps:

Step 1 On the MML client, run the LST SRVCLKSRC command to check the configuration of clock sources.




Step 2 On the MML client, run the RMV SRVCLKSRC command to remove the clock source that is not planned.

Step 3 On the MML client, run the ADD SRVCLKSRC command to add a clock source required by the network planning. To add more clock sources, run this command repeatedly.

Step 4 On the MML client, run the LST SRVCLKSRC command to confirm that the configuration of clock sources complies with the network planning.

----End



3.6.5 Changing the Clock Source Switching Mode The following modes are available for clock source switching:

Free: The IPCLK1000 uses the free-run timing signals generated by the internal oscillator as the clock source input.

Manual: The input timing signals at a specific port is manually set to be the clock source input.

Auto: Based on the priorities of the clock sources, the IPCLK1000 automatically selects the timing signals imported to a specific port as the clock source input. If the clock source is faulty, the IPCLK1000 then automatically switches to the clock source that takes priority over any other available clock source.

At a time, the IPCLK1000 can use only one clock source.

To change the clock source switching mode, perform the following steps:

Step 1 On the MML client, run the LST SRVCLKMODE command to check the clock source switching mode.




Step 2 On the MML client, run the SET SRVCLKMODE command to set the clock source switching mode to the planned mode.

----End

3.6.6 Reconfiguring the GPS Data When the IPCLK1000 uses the clock source from the built-in satellite card, you need to configure the GPS-related data, that is, the working mode of the satellite card, the GPS mask angle, and the delay on the feeder.

To reconfigure the GPS data, perform the following steps:

Step 1 On the MML client, run the LST GPSPARA command to check the initial settings of the GPS parameters.




Step 2 On the MML client, run the SET GPSPARA command to set the GPS parameters to the planned values.

----End



3.6.7 Changing the Output Clock Frequency When the IPCLK1000 needs to provide a clock for other equipment, you need to set the output clock frequency. This clock frequency refers to the frequency of the clock exported from the port labeled OUT-CLK on the panel of the IPCLK1000.

For the IPCLK1000, the server-oriented task is the same as the client-oriented task in terms of the principles and procedure. The difference lies in the commands to be run.

Performing the Task for the IPCLK1000 Acting as a Server To change the output clock frequency of an IPCLK1000 acting as a server, perform the following steps:

Step 1 On the MML client, run the LST SRVCLKOUT command to check the initial setting of the output clock frequency.




Step 2 On the MML client, run the SET SRVCLKOUT command to set the output clock frequency.

----End

Performing the Task for the IPCLK1000 Acting as a Client To change the output clock frequency of an IPCLK1000 acting as a client, perform the following steps:

Step 1 On the MML client, run the LST CLTCLKFREQ command to check the initial setting of the output clock frequency.




Step 2 On the MML client, run the SET CLTCLKFREQ command to set the output clock frequency.

----End

3.7 Verifying the IPCLK1000 Functionality This verification is performed before the IPCLK1000 is connected to IP clock clients. Therefore, the focus of the verification lies in the status of the IPCLK1000.

To verify the IPCLK1000 functionality, perform the following steps:



Step 1 On the MML client, run the LST ALMAF command to query active alarms.

If... Then...

There is any active alarm, Clear the alarm according to the alarm help.

Any alarm fails to be cleared, Record the alarm in the table as described in section 3.9 "Checklist for IPCLK1000 Commissioning."

Step 2 On the MML client, run the DSP BRD command to confirm that the running state of the IPCLK1000 is normal.

Step 3 On the MML client, run the DSP SRVCLKSTAT command to confirm that the clock source status of the IPCLK1000 is normal.

Step 4 (Optional; required when the output clock frequency is configured for the IPCLK1000 that acts as a server) On the MML client, run the LST SRVCLKFREQ command to confirm that the output clock frequency of the IPCLK1000 is consistent with the setting.

Step 5 (Optional; required when the output clock frequency is configured for the IPCLK1000 that acts as a client) On the MML client, run the LST CLTCLKFREQ command to confirm that the output clock frequency of the IPCLK1000 is consistent with the setting.

----End

3.8 Configuring the IPCLK1000 to Be Under the M2000 You can configure the IPCLK1000 to be under the centralized management of the M2000. The prerequisites for this task are as follows:

The IPCLK1000 passes local office verification. The OM network passes commissioning. The M2000 is operational. The version of the M2000 is compatible with the version of the IPCLK1000.

When the IPCLK1000 and the M2000 are located on the same network segment, no route needs to

be configured before this task. When the IPCLK1000 and the M2000 are located on different network segments, the route from the

IPCLK1000 to the M2000 needs to be configured before this task.

To configure the IPCLK1000 to be under the management of the M2000, perform the following steps:

Step 1 Connect the IPCLK1000 to the OM network by connecting one end of the straight-through cable to the hub connected to the IPCLK1000 and connecting the other end to the device such as a hub or router.

Step 2 On the MML client, run the LST IPRT command to check whether any route from the IPCLK1000 to the M2000 is configured on the IPCLK1000.

If... Then...

The route is configured, This task ends.

No route is configured, Go to Step 3.



Step 3 On the MML client, run the ADD IPRT command to configure a route from the IPCLK1000 to the M2000. In this step, set the destination IP address to the address of the network where the M2000 server is located, and set the next hop address to the IP address of the router connected to the IPCLK1000.

Table 3-10 describes an example.

Table 3-10 Example of route from the IPCLK1000 to the M2000

Scenario The IP address of the M2000 server is 10.11.100.23, and the subnet mask is 255.255.255.0. The IPCLK1000 is connected to the M2000 through a router, whose IP address is 172.121.139.10.

Operation Run the ADD IPRT command. Set the port type to DEBUG, destination IP address to 10.11.100.0, subnet mask to 255.255.255.0, and next hop to 172.121.139.10. The complete command is as follows: ADD IPRT:FCCTYPE=DEBUG, DESTADDR="10.11.100.0",

MASK="255.255.255.0", NEXTHOP="172.121.139.10";

Step 4 Notify the personnel on the M2000 side to create the IPCLK1000 on the M2000.

Then, the IPCLK1000 is under the management of the M2000.

----End

4 Interconnection Between the IPCLK1000 and an IP Clock Client IPCLK1000 User Guide


4.1 Preparing for the Interconnection 4.1.1 Checking Status

Status of the IPCLK1000 The IPCLK1000 works as a server properly and has passed the commissioning.

Status of the IP Clock Client The IP clock client can be an AP, a NodeB, a BTS, or an IPCLK1000. The IP clock client works properly and has passed the commissioning.

4.1.2 Preparing Tools, Instruments, and Devices The IPCLK1000 is already connected to the LMT or M2000. They work properly. You need to prepare cables, routers, hubs, and other tools and instruments.

4.1.3 Praparing Data for the Interconnection Data negotiation should be performed before the interconnection. The data includes IP addresses and routes.

Table 4-1 Data for interconnection

Item Value Example

Working mode of the IPCLK1000

Server or Client

Port used for interconnection FE or GE

Type of the peer client NodeB/BTS or AP

Network properties of the IPCLK1000

Ethernet port parameters (auto negotiation, duplex mode, or speed), packet transmission parameters (transmission frequency and time setting), Differentiated Service Code Point (DSCP) priorities of packets

If an IPCLK1000 works as the peer client, you need to set the peer client type to NodeB/BTS at the server.



4.2 Performing Operations at the IP Clock Server 4.2.1 Physical Connection

Install the cable according to the field capacity and networking requirements. Connect the service port on the IPCLK1000 to the associated network equipment.

At a time, either the service FE port or the GE optical port, not both, is available for interconnection. For details about how to install the cable, refer to section 3.3.3 "Installing Cables."

4.2.2 Data Configuration The purpose of data configuration is to interconnect the IPCLK1000 and the client, that is, to enable them to communicate with each other properly.

Before you perform each step, you can use the associated query command to check the default settings of the IPCLK1000. The only difference between the query command and the command used in a step is that the query command begins with LST while the command used in the step begins with ADD or SET. If the queried settings are consistent with the required settings, that step is unnecessary.

To configure data at the server for interconnection, perform the following steps:

Step 1 On the MML client, run the SET SYSWORKMODE command to set the working mode of the IPCLK1000 to Server.

Step 2 On the MML client, run the SET CLIENTMODE command to set the type of the IP clock client and the type of port for services. The IPCLK1000 supports only one clock client type and one service port type at a time.

Step 3 (Optional; required when the IP clock server and the IP clock client are located on different network segments) On the MML client, run the ADD IPRT command to configure a route for the service port, through which the IPCLK1000 is connected to the IP clock client.

Step 4 On the MML client, run the SET ETHPORT command to set the parameters for the service port. The parameters include the duplex mode and the speed.

Step 5 On the MML client, run the SET PKTSENDPARA command to set the packet transmission parameters, such as the transmission frequency and time setting. It is recommended that the transmission frequency be set to 50 packets per second and that the transmission time not be set.

Step 6 On the MML client, run the SET DSCPPRIORITY command to set the DSCP priorities of packets.

After you run the SET SYSWORKMODE, SET CLIENTMODE, or SET ETHPORT command, you need to reset the IPCLK1000 to validate the configuration.

----End

4 Interconnection Between the IPCLK1000 and an IP Clock Client IPCLK1000 User Guide


4.3 Performing Operations at the IP Clock Client 4.3.1 Configuring a Common IP Clock Client

Physical Connection Connect the service cable of the IP clock client to the network. In addition, ensure that the software of the IP clock client supports the client functionality.

If an IPCLK1000 serves as the IP clock client, its host software does not have to be upgraded. That is because the host software already supports the client functionality.

Data Configuration Configure the service IP address of the IPCLK1000 and the route on the IP clock client, so as to ensure that the client can be connected to the server.

4.3.2 Configuring an IPCLK1000 as an IP Clock Client When the peer equipment is a NodeB, a BTS, or an AP, an IPCLK1000 can be installed on the peer side, if the peer equipment fails to extract timing IP packets. The IPCLK1000 can work as an IP clock client, which restores timing signals for the NodeB, BTS, or AP. To achieve that, you need to configure the IPCLK1000 to be a client that is connected to the IPCLK1000 server.

Physical Connection Connect one end of the service cable to the service FE port on the panel of the IPCLK1000 that acts as a client, and connect the other end to the network.

When the IPCLK1000 acts as an IP clock client, only the service FE port can be used as the service port. In addition, connect the port labeled OUT-CLK on the panel of the IPCLK1000 to the input clock port on the device that the IPCLK1000 serves.

Data Configuration At a time, one IP clock client can be connected to a maximum of two IPCLK1000 servers for redundancy of clock sources.

Before you perform each step, you can use the associated query command to check the default settings of the IPCLK1000. The only difference between the query command and the command used in a step is that the query command begins with LST while the command used in the step begins with ADD or SET. If the queried settings are consistent with the required settings, that step is unnecessary.

To configure data at the IPCLK1000 acting as a client for interconnection, perform the following steps:

Step 1 On the MML client, run the SET SYSWORKMODE command to set the working mode of the IPCLK1000 to Client.



Step 2 On the MML client, run the ADD CLTCLKSRC command to add the IP address of the clock server to the client. For redundancy, you can add the IP addresses of two servers to one client in this step.

Step 3 (Optional; required when the IP clock server and the IP clock client are located on different network segments) On the MML client, run the ADD IPRT command to configure a route for the service port, through which the client is connected to the IPCLK1000 server.

Step 4 Set the output clock frequency as required. For details, refer to section 3.6.6 "Reconfiguring the GPS Data."

After you run the SET SYSWORKMODE command, you need to reset the IPCLK1000 to validate the configuration.

----End

4.4 Verifying the Interconnection After you configure data for interconnection between the IPCLK1000 and the IP clock client, you need to verify the interconnection by performing the following steps:

Step 1 On the server side, run the DSP CLINETINFO command on the MML client to check whether the client works properly.

Step 2 If the IP clock client is an IPCLK1000, run the DSP LINKTRANSSTATISTIC command on the MML client on the IP clock client side.

You can check whether the packet reception works properly by checking the statistics of the timing packets received by the clock client from the clock server.

Before you run the DSP LINKTRANSSTATISTIC command, you should run the STR LINKTRANSSTATISTIC command to start a packet analysis and run the STP LINKTRANSSTATISTIC command to stop the analysis.

Step 3 If the IP clock client is a NodeB, a BTS, or an AP, run the associated command on the clock client side to check the packet reception statistics.

For details about the command to be run at the clock client, refer to the associated MML help.

5.3.4 Replacing the IPCLK1000 If any irreplaceable component of the IPCLK1000 is faulty, you need to replace the whole IPCLK1000.

Prerequisites The new IPCLK1000 is ready. The hardware and software configurations of the new

IPCLK1000 are the same as those of the faulty IPCLK1000. Tools and materials are ready. They are the ESD wrist strap, cross screwdriver, straight

screwdriver, ESD box or bag, dustfree cotton cloth, and fiber cleaner.

Context It takes about 30 minutes to replace the IPCLK1000. The time covers the activities of removing the faulty IPCLK1000, installing the new IPCLK1000, and resuming the services.




Procedure Step 1 On the MML client, run the ULD CFGFILE command to upload the data configuration files

onto the LMT.

Step 2 Label the cables connected to the faulty IPCLK1000.

Step 3 Set the power switch on the IPCLK1000 to OFF. Then, power off the external power supply.

Step 4 Disconnect all the cables from the panel of the IPCLK1000 and insulate the cables.

Step 5 Remove the faulty IPCLK1000 case and put it into an ESD bag.

When you remove the faulty IPCLK1000, you should remove the following parts in sequence: the power cable, signal cables, the PGND cable, screws on the IPCLK1000, and the IPCLK1000 case.

Step 6 Fetch out the new IPCLK1000. Check that the IPCLK1000 is in good condition and that its version and configurations are consistent with those of the faulty IPCLK1000. Then, install the new IPCLK1000.

For details, refer to section 3.3 "Installing the IPCLK1000 Hardware."


For details, refer to section 5.1.1 "Powering On the IPCLK1000."

Step 8 On the MML client, run the DLD CFGFILE command to download the data configuration files to the new IPCLK1000.

Step 9 On the MML client, run the LST VER command to check whether the active software version is correct.

Step 10 If the software version is incorrect, upgrade the host software.

For details, refer to section 5.4 "Upgrading the Host Software."

Step 11 Restart the LMT application and log in to the IPCLK1000. On the MML client, run the DSP BRD command to check that the IPCLK1000 runs properly.

----End

Postrequisites After you replace the IPCLK1000, check the LMT or M2000 to ensure that related alarms are cleared.

Contact Huawei local office to handle the faulty IPCLK1000.

5.4 Upgrading the Host Software You can upgrade the host software of the IPCLK1000 either on the LMT or on the M2000. The two ways use the same commands and methods.



The M2000 supports upgrade of multiple IPCLK1000 in batches, but the LMT supports upgrade of only one IPCLK1000 in a single operation. Therefore, you can choose one of them, based on the field conditions. For details about the operation, refer to section 3.5 "Upgrading the Host Software."
