Returning a NFX350 Device or Component for Repair or Replacement

If you need to return a NFX350 device or component to Juniper Networks for repair or replacement, follow this procedure:

  1. Determine the serial number of the device or component. For instructions, see Locating the Serial Number on an NFX350 Device.
  2. Obtain a Return Materials Authorization (RMA) number from the Juniper Technical Assistance Center (JTAC) as described in Returning the NFX350 Chassis or Components.
    Note:

    Do not return any device or component to Juniper Networks unless you have first obtained an RMA number. Juniper Networks reserves the right to refuse shipments that do not have an RMA. Refused shipments are returned to the customer through collect freight.

  3. Pack the NFX350 device or component for shipping as described in Packing NFX350 Device Components for Shipping.

For more information about return and repair policies, see the customer support page at https://www.juniper.net/support/guidelines.html .

If the device is operational and you can access the CLI, you can list serial numbers for the device with a CLI command.

Listing the Device and Components Details with the CLI

To list the device and device components and their serial numbers, enter the following CLI command:

The following output lists the device components and serial numbers for a NFX350 device:

Packing NFX350 Device Components for Shipping

CAUTION:

Do not stack the NFX350 device components. Return individual components in separate boxes if they do not fit together on one level in the shipping box.

To pack and ship NFX350 device components:

  • Place individual FRUs in antistatic bags.

  • Ensure that the components are adequately protected with packing materials and packed so that the pieces are prevented from moving around inside the carton.

  • Close the top of the cardboard shipping box and seal it with packing tape.

  • Write the RMA number on the exterior of the box to ensure proper tracking.
