Step 14

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.
