Chapter 3 Troubleshooting Finding the Switch Serial Number Step 4 Step 5 Make the same Ethernet and Gigabit Ethernet connections on the replacement switch (as were on the failed switch). Power on the replacement switch. Note If you add a replacement switch that has a later Cisco IOS release to the running stack, the replacement 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. Finding the Switch Serial Number If you contact Cisco Technical Assistance, you need to know the serial number of your switch. Use these figures to locate the serial number on your switch. You can also use the show version command to get the serial number. • Figure 3-1, Catalyst 3750-24FS and 3750V2-24FS Switch Serial Number Location • Figure 3-2, Catalyst 3750G-12S and 3750-12S-SD Switch Serial Number Location • Figure 3-3, Catalyst 3750G-16TD Switch Serial Number Location • Figure 3-4, Catalyst 3750-24PS Switch Serial Number Location • Figure 3-5, Catalyst 3750G-24PS and 3750G-24TS-1U Switches Serial Number Location • Figure 3-6, Catalyst 3750G-24TS Switch Serial Number Location • Figure 3-7, Catalyst 3750-24TS and 3750V2-24TS Switch Serial Number Location • Figure 3-8, Catalyst 3750-24PS and 3750V2-24PS Switch Serial Number Location • Figure 3-9, Catalyst 3750G-24WS Switch Serial Number Location • Figure 3-10, Catalyst 3750-48PS and 3750V2-48PS Switch Serial Number Location • Figure 3-11, Catalyst 3750G-48PS and 3750G-48TS Switches Serial Number Location • Figure 3-12, Catalyst 3750-48TS and 3750V2-48TS Switch Serial Number Location Figure 3-1 Catalyst 3750-24FS and 3750V2-24FS Switch Serial Number Location OL-6336-10 Catalyst 3750 Switch Hardware Installation Guide 3-7
