CAUTION: If you meet strong resistance when attempting to seat the line module or
IOA using the ejectors, remove it from the chassis and confirm that the slot is designed
to hold the component. Also, be sure that you have aligned the top and bottom edges
in the correct matching tracks.

NOTE: Tighten the captive screws completely before installing an adjacent module
so that proper EMI gasket compression occurs. Failure to do this can make it difficult
to install adjacent modules.
CAUTION: Do not overtighten the screws.

Removing Modules and IOAs

This section describes the procedures for removing modules and IOAs. For a list of
hot-swappable IOAs, see Table 4 on page 32.
NOTE: We recommend that you issue the slot disable command from the CLI before
removing a line module or IOA.

an SRP module, the system's NVS card can become corrupted.

Removing Modules and IOAs
Verify that the ejectors are in the open position, as shown in Figure 19 on
page 39.
Guide the line module or IOA into the chassis by placing it between the guides
of the selected slot and pushing the module until it stops.
The module or IOA stops sliding when the ejectors make contact with the chassis.
Insert the line module or IOA into the midplane by simultaneously depressing
both ejectors (as shown in Figure 19 on page 39) and exerting forward pressure
on the module.
Tighten the module's captive screws using a No. 2 Phillips screwdriver.
