If you are returning a router or component to Juniper Networks for repair or replacement, you must locate
the serial number of the router 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 Return Material Authorization” on page 138.
If the router is operational and you can access the command-line interface (CLI), you can list serial numbers
for the router 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 router or component.
NOTE: If you want to find the serial number ID label on a component, you need to remove the
component from the router chassis, for which you must have the required parts and tools available.
Listing the Chassis and Component Details Using the CLI
To list the MX204 chassis and the components and their serial numbers, use the show chassis hardware
CLI operational mode command.
