Locating the Serial Number on a QFX5110 Device or Component

 

If you are returning a switch or 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 a Return Materials Authorization (RMA). See Contact Customer Support to Obtain Return Material Authorization.

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 switch or component.

Note

If you want to find the serial number ID label on a component, you need to remove the component from the switch chassis, for which you must have the required parts and tools available.

Listing the Chassis and Component Details Using the CLI

To list the QFX5110 switch and components and their serial numbers, use the show chassis hardware CLI operational mode command.

user@device> show chassis hardware
Note

You must remove the fan module to read the fan serial number from the serial number ID label. The fan module serial number cannot be viewed through the CLI. Fan Tray 2 refers to the third module from the left, counting from 0.

Locating the Chassis Serial Number ID Label on a QFX5110

The chassis serial number ID label is located on the right side of the QFX5110 port panel. On legacy switches, or switches with an LCD, the port panel is referred to as the front panel. See Figure 1 for an example of where to find the serial number ID.

Locating the Serial Number ID Labels on FRU Components

The power supplies and fan modules installed in a QFX5110 are field-replaceable units (FRUs). For each FRU, you must remove the FRU from the switch 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. See Figure 2 for an example of where to find the serial number ID.
