Return an EX4400 Chassis or Components
How to Return an EX4400 Switch or Component for Repair or Replacement
If you need to return a switch or hardware component to Juniper Networks for repair or replacement, follow this procedure:
For more information about return and repair policies, see the customer support page at https://www.juniper.net/support/guidelines.html.
Locate the Serial Number on an EX4400 Switch or Component
If you are returning a switch or hardware 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 Return Material Authorization (RMA).
If the switch is operational and you can access the 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 physical switch or component.
If you want to find the serial number on the physical switch component, you will need to remove the component from the switch chassis, for which you must have the required parts and tools available.
- List the Switch and Components Details with the CLI
- Locate the Chassis Serial Number ID Label on an EX4400 Switch
- Locate the Serial Number ID Labels on FRUs in an EX4400 Switch
List the Switch and Components Details with the CLI
To list the switch and switch components and their serial numbers, enter the CLI command
show chassis hardware extensive.
The following output lists the switch components and serial numbers for an EX4400-48F switch. The output is similar for the other models.

Locate the Chassis Serial Number ID Label on an EX4400 Switch
The serial number ID label is located on the right-hand side panel of the chassis on EX4400 switches (see Figure 1).

Locate the Serial Number ID Labels on FRUs in an EX4400 Switch
The power supplies, fan modules, and extension modules installed in EX4400 switches are field-replaceable units (FRUs). You must remove the FRU from the switch chassis to see its serial number ID label.

Pack EX4400 Switch Components for Shipping
Ensure that you have the following parts and tools available:
-
Antistatic bag, one for each component—not provided
-
An ESD grounding strap—not provided
If you need to transport a switch component to another location or return a component to Juniper Networks, you need to pack the component securely in its original packaging to prevent damage during transportation.
Do not stack switch components. Return individual components in separate boxes if they do not fit together on one level in the shipping box.
To pack the switch components:
-
Place individual components in antistatic bags.
-
Use the original packing materials if they are available. If the original packing materials are not available, ensure the component is adequately packed to prevent damage during transit. The packing material you use must be able to support the weight of the component.
-
Ensure that the components are adequately protected by wrapping them well with packing materials. Pack the component in an oversized box (if the original box is not available) with extra packing material around the unit so that the component is prevented from moving around inside the box.
-
Securely tape the box closed.
-
Write the RMA number on the exterior of the box to ensure proper tracking.
