ejectors (as shown in Figure 20) and exerting forward pressure on the module.

the module to sit correctly.
Installing Line and I/O Modules
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.
Installing a Line Module or an I/O Module
To install a module:
1. Ground yourself by using an antistatic wrist strap or other device and connect
it to the ESD grounding jack on the chassis.
2. Choose the slot where you want to insert the module.
NOTE: Line modules are in the front of the system and I/O modules are in the
back of the system.
