Finding the Switch Serial Number Chapter 4 Troubleshooting Finding the Switch Serial Number If you contact Cisco Technical Assistance, you need to know the switch serial number. Figure 4-1 shows the serial number location. You can also use the show version privileged EXEC command to see the switch serial number. Figure 4-1 Switch Serial Number Location SN: XXXNNNNXXXX 253192, 781-00659-01 A0 CONSOLE STACK 1 AUX RESET STACK 2 S-PWR RPS S-PWR AC OK PS OK C3KX-PWR-715WAC AC OK PS OK C3KX-PWR-715WAC Replacing a Failed Data Stack Member (Catalyst 3750-X Switches) To replace a failed data stack member: 1. The replacement switch must be a Catalyst 3750-X switch. 2. Power down the failed switch. Remove AC or DC input power, and if the switch is part of a StackPower stack, remove the StackPower cables. 3. Make sure the replacement switch is powered off, and then connect it to the stack. If you had manually set the member numbers for the switch stack, manually assign the member number of the failed switch to the replacement switch. To manually assign the stack member number, see the switch software configuration guide on Cisco.com. 4. Make the same Gigabit Ethernet connections on the replacement switch that were on the failed switch. 5. Reinstall any modules and cable connections. 6. Power on the replacement switch. 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.
