Locating the Serial Number on an EX4550 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 Materials 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. See Installing and Removing EX4550 Switch Hardware Components.
Listing the Switch and Components Details with the CLI
To list the switch and switch components and their serial numbers, enter the following CLI command:
show chassis hardware
The following output lists the switch components and serial numbers for an EX4550-32F-AFO switch:

Locating the Chassis Serial Number ID Label on an EX4550 Switch
The serial number ID label is located on the rear panel of an EX4550 switch. See Figure 1.
Locating the Serial Number ID Labels on FRUs in an EX4550 Switch
The power supplies, fan modules, expansion modules, and the Virtual Chassis module installed in EX4550 switches are field-replaceable units (FRUs).
For each of these FRUs, you must remove the FRU from the switch chassis to see the FRU’s serial number ID label.
Power supply—The serial number ID label is on the top of the power supply. Figure 2 shows the location of the serial number ID label on an AC power supply and Figure 3 shows the location of the serial number ID label on a DC power supply. See Removing an AC Power Supply from an EX4550 Switch or Removing a DC Power Supply from an EX4550 Switch .
Virtual Chassis module—The serial number ID label is on the circuit board. Figure 7 shows the location of the serial number ID label. See Removing a Virtual Chassis Module from an EX4550 Switch.

Packing EX4550 Switch Components for Shipping
To pack the switch components, follow the instructions here.
Ensure that you have the following parts and tools available:
Antistatic bag, one for each component
ESD grounding strap
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.
