Replacing A Failed Stack Member; Serial Number Location - Cisco Catalyst 3750 Hardware Installation Manual

Chapter 3 Troubleshooting

Replacing a Failed Stack Member

If you need to replace a failed stack member, you can hot swap or replace the switch by following this
procedure:
Get a replacement switch that has the same model number as the failed switch.
Step 1
Power down the failed switch.
Step 2
Make sure the replacement switch is powered off, and then connect the replacement switch to the stack.
Step 3
Note
Make the same Ethernet and Gigabit Ethernet connections on the replacement switch (as were on the
Step 4
failed switch).
Power on the replacement switch.
Step 5
The replacement switch will have the same configuration for all the interfaces as the failed switch and
will function the same as the failed switch.

Serial Number Location

If you need to know the serial number of your switch when requesting technical assistance, the
Catalyst 3750G integrated wireless LAN controller switch serial number is on the rear of the switch,
second label from the left, as shown in
Figure 3-1
SN: XXXNNNNXXXX
OL-6336-06
If you had manually set the member numbers for any members in the stack, you need to manually
assign the replacement switch the same member number as the failed switch. To assign the
member number manually, see the switch software configuration guide.
