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” on page 621.
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.
