Removing or Replacing a Module

Use this section to do either of the following:

■ Replace one module with another

■ Remove a module without replacing it

Figure 10. Removing the Module from the Slot

1. Remove any network cables from the ports on the module.

2. Loosen the screws in the extractor handles of the module you want to

remove from the switch. (Refer to figure 10, above.)

3. Simultaneously pull both extractor handles toward you and down until

the module releases from the slot and the Fault and status LEDs for that

slot are off.

Note During removal (or installation), the module and switch connectors will be

only partially connected momentarily. The Fault LED for the slot flashes

rapidly to indicate this state until the module is removed or properly installed.

(The other modules in the switch will continue to forward packets normally,

but other switch functions will be suspended until the module is removed or

properly installed.)

4. Slide the module out of the slot.
