Step 10 Push the module toward the back of the chassis and make sure it is clipped in by the levers on both sides. (See Figure 4-24.)

Step 11

Repeat Step 4 to Step 10 for the other modules you need to replace.

Step 12

If you are installing a clock module, secure the module to the backplane using the screws from the earlier

 

removal.

Step 13

Replace the supervisor engines and switching modules to their previous slots.

Step 14

Restore power to the switch.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Verify the New Modules

After the switch is reassembled and power is restored, connect a terminal to the supervisor engine and monitor the boot process. Look for the following messages (or any others), which may indicate a problem with the replaced modules:

00:00:20: %C4K_SUPERVISOR-2-MUXBUFFERNOTPRESENT: Mux buffer (WS-X4K-MUX) 3 is not present

00:00:20: %C4K_SUPERVISOR-2-MUXBUFFERNOTPRESENT: Mux buffer (WS-X4K-MUX) 4 is not present

00:00:20: %C4K_SUPERVISOR-2-MUXBUFFERNOTPRESENT: Mux buffer (WS-X4K-MUX) 7 is not present

The above messages (either at startup or output from a show logging command) indicate that the mux-buffer is not present in slots 3, 4 and 7. You need to reinsert and reseat the modules in those slots.

If the switch has already started up, you may also verify the correct function of the new modules with the show logging command.
