CHAPTER 5 Installing Modules

8Tighten the module’s captive screws using a Phillips screwdriver. Alternately turn each screw several times before tightening them completely to allow 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 system diagnostics fail, and after the line module has tried to reboot, its status will be “inactive” when you issue the show version command.

Installing a Line Module or an I/O Module

To install a module:

1Ground yourself by using an antistatic wrist strap or other device.

2Choose 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.

5Verify that the ejectors are in the open position, as shown in Figure 5-5.

6Guide the module into the chassis by placing it between the guides of the selected slot and pushing the module until it stops.
