Locating the Serial Number on a QFX3500 Device or Component
If you are returning a device or component to Juniper Networks for repair or replacement, you must locate the serial number of the device 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 device is operational and you can access the command-line interface (CLI), you can list serial numbers for the device 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.
If you want to find the serial number ID label on a component, you need to remove the component from the device chassis, for which you must have the required parts and tools available.
Listing the Chassis and Component Details Using the CLI
To list the QFX3500 device and components and their serial numbers,
use the show chassis hardware CLI operational mode command.
If you are using the QFX3500 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.

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. Fan Tray 2 refers to the fan modules located in the management board.
Locating the Chassis Serial Number ID Label on a QFX3500 Device
The chassis serial number ID label is located on a sliding panel to the right of the fan tray on a QFX3500 device. See Figure 1.
Locating the Serial Number ID Labels on FRU Components
The power supplies, fan trays, and management board installed in QFX3500 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.
Management board—The serial number ID label is on the circuit board.
