Locating the Serial Number on a QFX3600 or QFX3600-I 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 Contacting Customer Support to Obtain a Return Materials Authorization for a QFX Series Device or Component.

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 device or component.

Note

If you want to find the serial number ID label on a component, you will 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 QFX3600 or QFX3600-I device and components and their serial numbers, use the show chassis hardware CLI operational mode command. For the QFX3600-I Interconnect device, or if you are using the QFX3600 device as a Node device in a QFabric system, you must first log in to the device using the request component login CLI operational mode command, or connect directly to the device through the console CON port on the front panel.

Note

You must remove the fan tray to read the fan tray serial number from the serial number ID label. The fan tray serial number cannot be viewed through the CLI.

Locating the Chassis Serial Number ID Label on a QFX3600 or QFX3600-I Device

The chassis serial number ID label is located on a sliding panel to the right of the QSFP+ ports on the front panel of a QFX3600 or QFX3600-I device. See Figure 1.

Locating the Serial Number ID Labels on FRU Components

The power supplies and fan trays installed in QFX3600 and QFX3600-I devices are field-replaceable units (FRUs). For each FRU, you must remove the FRU from the device 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.
