chassis to see the FRU serial number ID label.

AC power supply—The serial number ID label is on the top of the AC power supply.

Fan tray—The serial number ID label is on the top of the fan tray.

Management board—The serial number ID label is on the circuit board.

Returning a QFX3500 Device or Component for Repair or Replacement on page 864

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.

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 EX4300 Switch Hardware Components.
