Introduction

This document describes how to determine the serial numbers of various replaceable components on Cisco Catalyst switches.

Prerequisites

Requirements

There are no specific requirements for this document.

Components Used

The information in this document is based on these software and hardware versions:

- Various Catalyst switches

- Various software versions

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Conventions

Refer to Cisco Technical Tips Conventions for more information on document conventions.

Background Information

The serial numbers are necessary to create a database of the parts in the network. When you create a service request with   Cisco Technical Support , you must have the serial number of the affected devices at hand. This requirement is especially the case when you need a replacement part, or return materials authorization (RMA).

The serial number of Cisco Catalyst switches cannot be modified. For management purposes, you can configure the Cisco Catalyst switches that run Cisco IOS® software to return a custom string. In order to create a custom string, issue the snmp-server chassis-id  command in global configuration mode.

Note: For specific information about show commands, see Show Commands.

Catalyst 6500

To determine the serial number for the chassis and other components, issue the  show idprom   command:

6506#show idprom ?

all           selects all FRU-types

backplane     specify backplane

clock         specify clock <number>

earl          specify earl <slot>

fan-tray      specify fan-tray <number>

interface     interface name

module        specify module <slot>

power-supply  specify power-supply <number>

rp            specify RP (MSFC) <slot>

supervisor    specify supervisor <slot>

vtt           specify VTT <number>

To obtain the chassis serial number, issue the  show idprom backplane  command:

6506#show idprom backplane

IDPROM for backplane #0

(FRU is 'Catalyst 6500 6-slot backplane')

OEM String = 'Cisco Systems'

Product Number = 'WS-C6506'

Serial Number = 'TBA03270652'

Manufacturing Assembly Number = '73-3436-01'

Manufacturing Assembly Revision = 'A0'

Hardware Revision = 1.0

Current supplied (+) or consumed (-) =  -A

To obtain the module serial number, issue the show idprom module slot <slot number> command. Alternatively, you can issue the  show module  command:

6506#show module

Mod Ports Card Type                              Model              Serial No.

Note: Use the  show diagbus  command to determine the serial number of port adapters on the Flex WAN module.

Catalyst 4500

Catalyst 4500 with Supervisor Engine 2

On the Catalyst 4500/4000 Supervisor 2, the chassis serial number is available via CLI in versions 5.5(10), 6.3(2), and later versions. In earlier versions, the  show version  command shows the Supervisor Engine serial number in the place of the chassis serial number. To obtain the serial number of the chassis in these earlier versions, check the external sticker on the chassis.

Catalyst 4500 Supervisor Engine II+/III/IV

To determine the serial number of the chassis and other components use the  show idprom  command:

Switch#show idprom ?

all           show all non-interface IDPROMs

chassis       show IDPROM for chassis

fan-tray      show IDPROM for system fan tray

interface     show contents of gbic connected to this interface

module        show IDPROM for module

power-supply  show IDPROM for power supply

supervisor    show IDPROM for supervisor

To obtain the chassis serial number use the  show idprom chassis  command:

Switch#show idprom chassis
