Finding The Switch Serial Number - Cisco 3750G-12S - Catalyst Switch - Stackable Hardware Installation Manual

Chapter 3 Troubleshooting
Make the same Ethernet and Gigabit Ethernet connections on the replacement switch (as were on the
Step 4
failed switch).
Step 5 Power on the replacement switch.
If you add a replacement switch that has a later Cisco IOS release to the running stack, the replacement
Note
switch automatically downgrades to the release that the stack is running. The replacement switch, rather
than the existing switches, reboots. The replacement switch then has the same configuration for all the
interfaces as those of the failed switch.
