Locating the Serial Number on an EX4500 Switch or Component
If you are returning a switch or hardware component to Juniper Networks for repair or replacement, you must locate the serial number of the switch or component. You must provide the serial number to the Juniper Networks Technical Assistance Center (JTAC) when you contact them to obtain Return Materials Authorization (RMA).
If the switch is operational and you can access the CLI, you can list serial numbers for the switch and for some components with a CLI command. If you do not have access to the CLI or if the serial number for the component does not appear in the command output, you can locate the serial number ID label on the physical switch or component.
![]() | Note: If you want to find the serial number on the physical switch component, you will need to remove the component from the switch chassis, for which you must have the required parts and tools available. See Installing and Removing EX4500 Switch Hardware Components. |
Listing the Switch and Components Details with the CLI
To list the switch and switch components and their serial numbers, enter the following CLI command:

Locating the Chassis Serial Number ID Label on an EX4500 Switch
The serial number ID label is located on the front left corner of the chassis on an EX4500 switch. See Figure 1.

Locating the Serial Number ID Labels on FRUs in an EX4500 Switch
The power supplies, fan tray, uplink modules, and the intraconnect module installed in EX4500 switches are field-replaceable units (FRUs).
For each of these FRUs, you must remove the FRU from the switch chassis to see the FRU’s serial number ID label.
- Power Supply—The serial
number ID label is on the top of the power supply. See Figure 2 to see the location
of the serial number ID label. See Removing a Power Supply from an EX4500 Switch.

- Fan tray—The serial number
ID label is on the top right corner of the fan tray. See Figure 3 to see the location of the
serial number ID label.See Removing a Fan Tray from an EX4500 Switch.
