7 Installing modules inside an outdoorcabinet

Purpose

This section describes the module installation process inside an outdoor cabinet.The recommended installation location for the Flexi WCDMA BTS modules isthe bottom of the cabinet. However, if you are going to use the site supportmodule, reserve the bottom half of the cabinet for that purpose and install themodules starting from the top of the cabinet.

Before you start

. If you are going to install cabinet options, such as the site support module,it is recommended that you do it before the module installation.

. Take the site pack from the bottom right corner of the cabinet.

Note

There are two air guide plates in the site pack. In Epsilon, when ESMA is inthe vertical racks, the plate is fixed next to the ESMA (right-hand side) toguide air circulation and to provide a fixing point for cables.

Warning

When handling the modules, always use the antistatic wrist strap. Thecabinet must be grounded, otherwise the antistatic wrist strap will notwork.

. four FPAAs

. one FPAA and three FPBAs

. one FPAA and three free slots for expansion.

Steps

1. Remove the fixing studs for the module casing.

2. Remove the support plate behind the cage nuts.

3. Detach the cage nuts from the module.

4. Remove the dummy panels.

5. Fix the cage nuts (from the module) on the rack on the left-hand side ofthe cabinet.

Further information

For FPAA and FPBA installation instructions, see section Installing Flexi PowerModule (FPMA) in the Installing the Modules document. The sub-modules canbe installed inside the FPMA before installing it into the cabinet.

8.2 Installing air filter

Purpose

The optional air filter can be used in case the environment is extremely dirty.

8.4.3 Installing PDU and site support module

Purpose

The optional site support module (FCSA) can be used with the outdoor cabinet toprovide long-term battery back-up time for the Flexi WCDMA BTS, and a spacefor installing LTE units. The PDU (Power Distribution Unit, WPUB or WPUC) isutilised when a site support module is used. The PDU converts the AC power intoDC power, which the base station uses.

The FCSA control card collects and converts alarms information from the fans,LTE units and MIBBU. The alarms are connected to EAC lines, which is donewith the use of dip switches on the board. The default settings are presented in thefollowing table. If necessary, the routing of alarms can be changed by adjustingthe dip switches.

8.4.4 Installing the rectifier units (WPMB/WPMC)

Purpose

The PDU provides four slots for the rectifiers. Each of the PDU versions (WPUB/WPUC) has its own rectifier unit: WPMB/WPMC. Install the rectifier units asdescribed in these instructions.

Before you start

Remove the dummy panels from the PDU.

DN70100525



Steps

1. Install the rectifier units.

Install the rectifier units in their places. Note that if the rectifier is the typethat has the retaining hooks (WPMB), the hooks must be in an openposition before fixing the unit in place. Use a small screwdriver in theholes in the upper left- and right-hand corners of the unit to release thehooks.

Note

The retaining hooks are fragile. Do not carry the unit by the retaining hooks.

Turn the breakers on the PDU front panel into the ON position.

Note

Do not switch on the breakers before the BTS installation is completed.

4. Close the lid.

8.4.5 Changing the alarm polarity of the WPUB unit

Before you start

The EAC alarm polarity can be set to two states, Normally Open or NormallyClosed.

The Normally Open state means that the galvanic EAC alarm circuit loop is openand electric current is not flowing through it. The corresponding EAC alarm isactivated if the EAC alarm circuit loop is closed.

The Normally Closed state means that the galvanic EAC alarm circuit loop isclosed and electric current is flowing through it. The corresponding EAC alarm isactivated if the EAC alarm circuit loop is opened.

The default alarm polarity is Normally Closed.

Note

Ensure that you set the EAC alarm polarity correspondingly during BTScommissioning.



Steps

1. To change the polarity for alarm relay output from the Normally Openstate to the Normally Closed state, connect the wires according to thefollowing table and figure Changing the alarm polarity of the WPUBunit, option B.

8.4.6 Changing the alarm polarity of the WPUC unit

Before you start

There are eight galvanic isolated alarm contacts for remote supervision of thealarms. Each alarm contact represents different alarm conditions. Alarm relaycoils are powered during normal operation. All alarm relays will give an alarmwith no AC or DC power connected to the system.

Figure 31. Alarm connection, 9-pin D-sub

Note

While it is recommended to change the polarity before installing the unit intothe cabinet, with the WPUC unit it is also possible to do this later.

Note

Always use the antistatic wrist strap when handling the WPUC.

Steps

1. Loosen the fixing screw and pull out the alarm interface unit using thehandle.

2. Use JP8 for setting the alarm relays to closed on alarm or open onalarm.

The jumper mounted between pins 1 and 2 on the jumpers (default) meansclosed on alarm for the corresponding relay.

The jumper mounted between pins 2 and 3 on the jumpers means open onalarm for the corresponding relay.

The jumper numbers correspond to the relay numbering (for instance, JP5to RL5).

Note

When the jumpers are mounted between pins 1 and 2, the alarm polarity isNormally Open. When the jumpers are mounted between pins 2 and 3, thealarm polarity is Normally Closed.
