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 toobtain a Return Materials Authorization (RMA). See “Contacting Customer
Support to Obtain Return Material Authorization” on page 131.
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.
