Installing Line and I/O Modules

Installing a Line Module or an I/O Module

CAUTION: If you meet strong resistance when attempting to seat the
module using the ejectors, remove it from the chassis and confirm that
the slot is designed to hold the module. Then verify, if applicable, that the
module matches its corresponding module (I/O module or line module).
Also, be sure that you have aligned the top and bottom edges in the correct
matching tracks.
Insert the module into the backplane by simultaneously depressing both ejectors (as
7.
shown in Figure 20 on page 38) and exerting forward pressure on the module.
Tighten the module's captive screws using a No. 2 Phillips screwdriver. Alternately
8.
turn each screw several times before tightening them completely to allow the module
to sit correctly.
CAUTION: Do not overtighten the screws.
This section describes the procedures for installing line and I/O modules.
NOTE: Install the I/O module before you install the corresponding line module;
otherwise, the diagnostics fail and the line module's status is listed as inactive
when you issue the show version command. If this occurs, remove and reinsert
the line module.
To install a module:
Ground yourself by using an antistatic wrist strap or other device and connect it to the
1.
ESD grounding jack on the chassis.
Choose the slot where you want to insert the module.
2.
NOTE: Line modules are in the front of the system and I/O modules are
in the back of the system.
