Locating the Serial Number on a QFX3100 Director 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 physical device or component.
If you want to find the serial number on the physical device component, you will need to remove the component from the device chassis, for which you must have the required parts and tools available.
Listing the Chassis Serial Number with the CLI
To list the QFX3100 device serial number from the CLI, use the show fabric administration inventory director-group status CLI command:
user@device> show fabric administration inventory
director-group status... Member Device Id/Alias Status Role ------ ---------------- ------- --------- dg0 0281012012000000 online master Member Device Id/Alias Status Role ------ ---------------- ------- --------- dg1 0281032012000000 online backup ...
Locating the Serial Number ID Label on a QFX3100 Director Device
The serial number ID label is located on the back of the chassis on a QFX3100 Director device. See Figure 1.
Locating Serial Number ID Labels on FRU Components
The power supplies, fan modules, HDD modules, and network modules are field-replaceable units (FRUs). For most of these FRUs, 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 right side of the AC power supply.
Fan module—The serial number ID label is on the top of the fan module.
HDD module—The serial number ID label is on the top of the HDD module.
Network module—The serial number ID label is on the left of the network module.
