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 .)
Figure 4-24 Securing the Module
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.
