2 Preparing for installation

2.1 Safety recommendations

To avoid any equipment damage or bodily injury caused by improper use, read the following safety recommendations before installation. Note that the recommendations do not cover every possible hazardous condition.

Regarding with installation and maintenance of this product, please make the engineer who acquired a right operating method to do that. Remove dust on and around the Switch regularly. Before cleaning the switch, unplug all power cords from the switch. Do not clean the

switch with wet cloth or liquid. Before moving the Switch, unplug all power cords from the switch. Do not place the switch near water or in a damp environment. Prevent water or

moisture from entering the switch chassis. Do not place the switch on an unstable case or desk. The switch might be severely

damaged in case of a fall. Ensure proper ventilation of the equipment room and keep the air inlet and outlet vents

of the switch free of obstruction. Connect the yellow-green protection grounding cable before power-on. Make sure the operating voltage is in the required range. Please don't open equipment. Breakdowns when opening, will be applying of the

guarantee. When replacing FRUs, including power modules and fan trays, wear an

ESD-preventive wrist strap to avoid damaging the units. Please be sure to do service operation of the equipment which is being used after a

power supply is off.

2.2 Connecting the RJ45 connector

NOTE: When connecting the RJ45 cable, wear a wrist strap to protect against static electricity.

Do not touch the RJ45 Ethernet cable terminal. If you touch the RJ45 Ethernet cable terminal which is connecting to the Switch, the interface circuit may be broken by the static electricity. When you connect the Console cable, you need also a same care.

2-1

Installation Guide


Figure 2-1 Connecting the RJ45 connector

2.3 Examining the installation site

The QX-S5500 Series switches must be used indoors.

Mount your switch in a rack or on a workbench and make sure: Adequate clearance is reserved at the air inlet and exhaust vents for ventilation. The rack or workbench has a good ventilation system. Identify the hot aisle and cold aisle at the installation site, and make sure ambient air

flows into the switch from the cold aisle and exhausts to the hot aisle. Identify the airflow designs of neighboring devices, and prevent hot air flowing out of

the bottom device from entering the top device. The rack is sturdy enough to support the switch and its accessories. The rack is well earthed. To ensure normal operation and long service life of your switch, install it in an environment that meets the requirements described in the following subsections.

2.4 Temperature/humidity

Maintain appropriate temperature and humidity in the equipment room. Lasting high relative humidity can cause poor insulation, electricity creepage,

mechanical property change of materials, and metal corrosion. Lasting low relative humidity can cause washer contraction and ESD and bring

problems including loose captive screws and circuit failure. High temperature can accelerate the aging of insulation materials and significantly

lower the reliability and lifespan of the switch. For the temperature and humidity requirements of different switch models, see "Overview".

2-2

Installation Guide


2.5 Cleanness

Dust buildup on the chassis may result in electrostatic adsorption, which causes poor contact of metal components and contact points, especially when indoor relative humidity is low. In the worst case, electrostatic adsorption can cause communication failure.

Table 2-1 Dust concentration limit in the equipment room

Substance Concentration limit (particles/m³) Dust ≤ 3 x 104 (no visible dust on the tabletop over three days) Note: Dust diameter ≥ 5 μm

The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion and premature aging of components, as shown in Table 2-2.

Table 2-2 Harmful gas limits in the equipment room

Gas Maximum concentration (mg/m3) SO2 0.2 H2S 0.006 NH3 0.05 Cl2 0.01

2.6 EMI

All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system, adversely affect the switch in a conduction pattern of capacitance coupling, inductance coupling, electromagnetic wave radiation, or common impedance (including the grounding system) coupling. To prevent EMI, take the following actions: Please take the effective measures to reduce the intervention the power supply

system exerts on the switch. Keep the switch far away from high-power radio launchers, radars, and equipment

with high frequency or high current. If AC power is used, use a single-phase three-wire power receptacle with protection

earth (PE) to filter interference from the power grid. Keep the switch far away from radio transmitting stations, radar stations, and

high-frequency devices. Use electromagnetic shielding, for example, shielded interface cables, when

necessary. Route interface cables only indoors to prevent signal ports from getting damaged by

overvoltage or overcurrent caused by lightning strikes.

2.7 Laser safety

The QX-S5500 Series switches are Class 1 laser devices.

3.2.3 Grounding the Grounding Cable

WARNING: Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection.

The power input end of the switch is connected with a noise filter, whose central ground is directly connected to the chassis, forming the so-called chassis ground (commonly known as PGND). This chassis ground must be securely connected to the earth so that the faradism and leakage electricity can be safely released to the earth, enhancing the EMS capability of the switch.

You can ground the switch by burying the grounding body into the earth. Landing resistance has to satisfy A kind landing (10 ohms) or D kind landing (100 ohms). When switch install to 19-inch standard cabinet based, ground a chassis appropriately.

3.3 Connecting the Console Cable

3.3.1 Console Cable

A console cable is an 8-core shielded cable. One end of the cable is a crimped RJ-45 connector, which is connected to the console port of the switch, and the other end is a DB-9 female connector, which is connected to the serial port on the console terminal, as shown below.

To establish normal communication, pin for transmission data has to make them match with pin for receive data in an opposite port. When a port of one device is MDI or MDI-X, and a port of the device opposite is already MDI or MDI-X, a crossing cable is necessary. The MDI/MDI-X type connects the same device to a crossing cable. When MDI and the other are MDI-X, a straight cable needs one port. A straight cable connects device different in the MDI/MDI-X type.

When the auto-MDI/MDI-X function is effective by RJ-45 Ethernet interface, the role of the pin is put together automatically.

NOTE: RJ-45 Ethernet interface of QX-S5500 series is supporting auto-MDI/MDI-X function. The auto-MDI/MDI-X function is effective at a port by default.

5.1.2 Connection by a twisted pair cable

10/100/1000BASE-T port of QX-S5500 series uses RJ-45 connector and supports auto-MDI/MDI-X function. Use a twisted pair cable of Category - more than 5 for a network connection of the switch.

I. Network connection procedure of the switch by a twisted pair cable

1) As occasion demands, make straight or a cross Ethernet cable. 2) A something of a twisted pair cable is connected to Ethernet RJ-45 port of the

connected switch. 3) Connect the other end of a twisted pair cable to Ethernet RJ-45 port of interconnect

equipment. 4) Check whether an LED in Ethernet RJ-45 port is normal.

5.2 Network connection by a fiber-optic cable

Installation Guide


5.2.1 Establishment of a SFP module

NOTE: This section describes establishment of a SFP module and an operational guideline.

I. Installation procedure of a SFP module

1) Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well grounded.

2) Raise to the module upper part until a latch of a SFP module is fixed. 3) Insert in a module in the slot and be crowded with both sides of the SFP module. 4) Force by a thumb until a SFP module is fixed. 5) Check that a latch of a SFP module is fixed.

WARNING: Do not remove the dust-proof cover before connecting a fiber optic-cable. When a fiber-optic cable is connected to each module, please establish each module after a fiber-optic

cable is removed. Don't touch joining terminal of a SFP module.

5.2.2 Connection of optical fiber connector and a SFP module

I. Optical fiber connector

When connecting an optical fiber, confirm that the kind of connectors and fibers match the type of the optical interface.

Optical interface of QX-S5500 series uses the LC fiber connector indicated in Figure 5-5.

Therefore specification of the software used at next-startup is completed. To confirm the upgrade of software, restart the switch. After a load of software has been completed when space of a flash memory isn't enough, it's possible to delete several files in the flash memory. It's recommended to delete the software which isn't used. Upload software using a FTP. Power interruption is not allowed during software loading.


The remote loading by using TFTP is similar to the remote loading by using FTP. The only difference is that it is TFTP that you use when loading software to the switch. In this case, the switch can only be used as a TFTP client. The remaining step after download is just same as the occasion of the remote load with a FTP.

7 Maintenance and Troubleshooting

7.1 Exchange of a power supply module

CAUTION: QX-S5526T has power supply module of the AC type and DC-type. You can select AC power module or DC power module for your switch as needed. Install power supply modules of the same model on the switch. for power supply redundancy or a maintenance exchange.

I. Installation tools

ESD-preventive wrist strap Phillips screwdriver

II. Exchange of a power supply module

1) Reduce a fixed screw of the power supply module using a screwdriver. 2) Draw an exchanged module and remove a slot. 3) Take new power supply module out from a package. 4) Confirm whether power supply module is for AC power supplies or DC power

supply.(see Figure 7-1)

Figure 7-1 Power supply module (left: AC power module, right: DC power module)

CAUTION: The power supply module is heavy, so please treat by both hands. Correctly orient the power module with

the power supply module slot, grasp the handle of the power supply module with one hand and pull the handle slowly with opposite hand. If only one power supply module is installed, install a power filler module in the empty power supply module slot for good ventilation of the switch.

To prevent damage to the connectors inside the switch chassis, insert the power supply module gently. If you encounter a hard resistance while inserting the power supply module, pull out the power module and insert it again.

When a fixed screw doesn't tighten well, there is a possibility that a power supply module isn't inserted right. Confirm whether a power supply module is inserted correctly.

7.2 Software Loading Failure

When a software load was failed, system must start up by original software, or perform an update locally from the Boot menu. Check the following and download software once again. A physical port is connected right. Make sure that sufficient space at a flash memory is available for the upgrading

software file. When there are no problems with both of a connection in a physical port and the free space of the flash memory, verify the message about an input error of the upgrade procedure shown to a terminal. 1) When a baud rate is established besides the 9600 bps after loading software in a case

with Xmodem, please verify whether it was set as 9600 bps once again. 2) When using TFTP, please verify whether the next is specified right. A server and the switch IP address are right. The name of the loaded software is right. The TFTP server address which moves on the program file is right. 3) When using FTP, please verify whether the next is specified right. A server and the switch IP address are right. The name of the loaded software is right. A username and a password are right.
