The device is a modular chassis and allows you to order any module as a Field
Replacement Unit (FRU). This section describes the procedures for installing or replacing
modules.

Installing and Replacing Modules

This section describes step-by-step procedures for installing or replacing modules.
6.1.1

Module Slot Assignment

The device's front-panel chassis provides slots (numbered as shown in the figure below) for
housing the main input/output (I/O) interface modules (i.e., TRUNKS, BRI, FXS, FXO,
MPM, and CRMX).
The guidelines for slot assignment for these modules include the following:
The CRMX module must always be housed in the slot located to the left of the Spare
Power Supply slot (as illustrated in the figure above).
The SWX LAN Expansion module must always be housed in the slot below the CRMX
module.
The TRUNKS, BRI, FXS, and FXO modules must be housed in consecutive slots. In
other words, if the device houses three modules, then they must occupy slots 1, 2, and
3 (no skipping of slots).
It is recommended to assign the TRUNKS, BRI, FXS, and FXO modules to the slots
(starting from Slot 1) according to the order of priority listed below:
1. TRUNKS
2. BRI
3. FXS and/or FXO
For example, if the device requires one TRUNKS module and two FXS modules, then
you must insert the TRUNKS module in Slot 1 and the two FXS modules in slots 2 and
3 respectively. If at a later stage, you wish to add a BRI module (for example), then
you must replace the FXS module in Slot 2 with the new BRI module, and then re-
insert this replaced FXS module in Slot 4.
Version 6.4
To prevent static electrical damage to the module's printed circuit board,
do not touch the components on the module. Instead, hold the module only
on the edges where no electrical components are located.
Cover all unoccupied module slots with blank panels. This ensures optimal
internal airflow pressure within the chassis.
