In Cisco Catalyst switches running Cisco IOS, you can find the serial numbers using the following commands on the various models:
Catalyst 6509 switch:
Switch1#show idprom backplane
IDPROM for backplane #0
(FRU is 'Catalyst 6500 6-slot backplane')
OEM String = 'Cisco Systems'
Product Number = 'WS-C6506'
Serial Number = 'TBAxxxxxxxx'
Manufacturing Assembly Number = '73-3436-01'
Manufacturing Assembly Revision = 'A0'
Hardware Revision = 1.0
Current supplied (+) or consumed (-) = -A
On a Catalyst 4500/4000 switch,
Switch1#show idprom chasis
Chassis Idprom :
Common Block Signature = 0xABAB
Common Block Version = 1
Common Block Length = 144
Common Block Checksum = 4081
