Article ID: KB11202 KB Last Updated: 06 Feb 2020Version: 5.0
Summary:

The serial number (S/N) is a unique identifier of Juniper products and is often required by Juniper Customer Service or Sales representatives for product identification.

This article explains how to retrieve the serial number on EX Series switches by reading it from a label on the chassis, by using the Command Line Interface, or via the J-Web interface.

 

Solution:

There are three methods to retrieve the serial number (S/N) from an EX Series switch (EX3200 and EX4200).

  • Physical Location - Locate the serial number on the EX Series switch chassis.

    The serial number is a 12-digit number, labeled on the rear panel of the chassis.

  • CLI - Retrieve the serial number by using CLI.

On the switch's CLI, issue the command show chassis hardware as in the example below:

 user@switch> show chassis hardware
 Hardware inventory:
 Item             Version  Part number  Serial number      Description
 Chassis                                BK0207442087      EX3200-48T
 FPC 0            REV X3   750-021259   BK0207442087      EX3200-48T, 8 POE
   CPU                     BUILTIN      BUILTIN           FPC CPU
   PIC 0                   BUILTIN      BUILTIN           48x 10/100/1000 Base-T
   PIC 1          REV X1   711-021270   AR0207421426      4x GE SFP
     Xcvr 0       REV 01   740-011782   P9904K1           SFP-SX
     Xcvr 3       REV 01   740-011782   P9908BY           SFP-SX
 Power Supply 0   REV 01   740-020957   AT0507430218      PS 320W AC
 Fan Tray                                                 Fan Tray

In this example we identify the serial number of the chassis (BK0207442087), Uplink module (AR0207421426), power supply (AT0507430218) and SFPs (P9904K1, P9908BY) installed on the uplink module.

  • J-WEB - Retrieve the serial number by using the J-Web HTTP interface.

The serial number of the chassis is available on the Monitor tab, under System View , Chassis Information.
