Removing a Switch Module

To remove a Model 5625HD switch module from the chassis:

1. Use a flat-tip screwdriver to loosen the two captive retaining screws that

secure the module to the chassis.

These screws are spring-loaded to pop outward when they are unscrewed from

the chassis. The screws are held in place on the module front panel by locking

washers.

2. Rotate the top and bottom inserter/extractor levers a way from the center

of the switch front panel to release the module from the backplane

connectors (Figure 3-6).

Figure 3-6. Releasing the Backplane Connectors

Note: Be sure to remove cables from all ports on the module, or disable all the

ports through the management i nterface, prior to hot-swapping.
