Locating an EX-series Switch or Switch Component Serial Number
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 command-line interface (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 (see Figure 1 and Figure 2).
Note: If you have to find the serial number on the physical switch component, you will need to remove the component from the switch chassis, so you must have the required removal tools and parts available.
Listing the Switch and Switch Components Details with the CLI
To list the switch and switch components and their serial numbers, enter the following command-line interface (CLI) command:
user@switch> show chassis hardware
Hardware inventory: Item Version Part number Serial number Description Chassis AL0207391164 EX3200-48T FPC 0 REV X1 711-021265 AL0207391164 EX3200-48T, 8 POE CPU BUILTIN BUILTIN FPC CPU PIC 0 BUILTIN BUILTIN 48x 10/100/1000 Base-T Fan Tray Fan Tray

Locating Switch FRU Component Serial Numbers
The power supplies, fan trays, and uplink modules installed in EX-series 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.
- Power Supply—The serial number is on the top of the power supply. See Removing a Power Supply from an EX-series Switch.
- Fan tray—The serial number is on the back of the fan tray. See Removing a Fan Tray from an EX-series Switch.
- Uplink module—The serial number is on the circuit board. See Removing an Uplink Module from an EX-series Switch.
