Locate the Serial Number on a QFX5120 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 Material 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.

List the Switch and Components Details with the CLI

To list the switch and switch components and their serial numbers, enter the following CLI command:

show chassis hardware

The following output lists the switch components and serial numbers for a QFX5120-48Y switch; the output is similar for other QFX5120 switches:

user@switch> show chassis hardware

Locate the Chassis Serial Number ID Label on a QFX5120 Switch

The serial number ID label is located on the top panel of the chassis on QFX5120-32C switches and on the right panel on QFX5120-48T, QFX5120-48Y, and QFX5120-48YM switches. Figure 1 shows the location of the serial number ID label on QFX5120-32C switches. Figure 2 shows the location of the serial number ID label on QFX5120-48T switches. Figure 3 shows the location of the serial number ID label on QFX5120-48Y switches. Figure 4 shows the location of the serial number ID label on QFX5120-48YM switches.

Locate the Serial Number ID Labels on FRUs in a QFX5120 Switch

The power supplies and fan module installed in QFX5120 switches are field-replaceable units (FRUs).

You must remove these FRUs from the switch chassis to see the serial number ID label.

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