6 Hardware Maintenance
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.
Warning: 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.
Note: Cover all unoccupied module slots with blank panels. This ensures optimal internal
airflow pressure within the chassis.
6.1 Installing and Replacing Modules
This section describes step-by-step procedures for installing or replacing modules.
Warning: Make sure that all unoccupied module slots are covered with blank panels.
This prevents dust from entering the chassis' and ensures even air flow within the
chassis for cooling.
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 ).
Figure 6-1: Module Chassis Slot Assignment
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 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
