Returning an EX4650 Chassis or Components
Returning an EX4650 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 .
Locating the Serial Number on an EX4650 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 the serial numbers for the switch and for some components using 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.

Listing the Switch and Components Details using 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 EX4650 switch:
user@switch> show chassis hardware
For information about the show chassis hardware
command,
see show chassis hardware.
Locating the Chassis Serial Number ID Label on an EX4650 Switch
The serial number ID label is located on the rear panel of the chassis on EX4650 switches. Figure 1 shows the location of the serial number ID label on EX4650 switches

Locating the Serial Number ID Labels on FRUs in an EX4650 Switch
The power supplies and fan modules installed in EX4650 switches are field-replaceable units (FRUs).
For each of these FRUs, you must remove the FRU from the switch chassis to view the serial number ID label of the FRU.
Power Supply—The serial number ID label is on the top of the power supply. Figure 2shows the location of the serial number ID label on a DC power supply.

Contact Customer Support to Obtain a Return Material Authorization
If you need to return a device or hardware component to Juniper Networks for repair or replacement, obtain an RMA number from JTAC. You must obtain an RMA number before you attempt to return the component.
After locating the serial number of the device or hardware component you want to return, open a service request with the JTAC on the Web or by telephone.
Before you request an RMA number from JTAC, be prepared to provide the following information:
-
Your existing service request number, if you have one
-
Serial number of the component
-
Your name, organization name, telephone number, fax number, and shipping address
-
Details of the failure or problem
-
Type of activity being performed on the device when the problem occurred
-
Configuration data displayed by one or more

Packing an EX4650 Switch or Component for Shipping
If you are returning an EX4650 switch or component to Juniper Networks for repair or replacement, pack the item as described below.
Before you begin packing the switch or its component:
Ensure that you have followed all the steps listed in Contact Customer Support to Obtain a Return Material Authorization.
Ensure that you have retrieved the original shipping carton and packing materials. Contact your JTAC representative if you do not have these materials, to learn about approved packing materials. See Contact Customer Support to Obtain a Return Material Authorization.
Ensure you understand how to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.
Packing an EX4650 Switch for Shipping
Before you pack the switch:
On the console or other management device connected to the switch, enter the CLI operational mode, and issue the following command to shut down the switch software:
user@switch> request system halt
Wait until a message appears on the console confirming that the operating system has halted.
Disconnect power from the switch by performing one of the following: • If the power source outlet has a power switch, set it to the OFF (0) position. If the power source outlet does not have a power switch, gently pull out the plug end of the power cord that is connected to the power source outlet.
Remove the cables that connect the switch to all external devices. See Disconnect a Fiber-Optic Cable.
Remove all optical transceivers installed in the switch. See Remove a Transceiver.
If you need to transport the switch to another location or return the switch to Juniper Networks, you must pack the switch securely in its original packaging to prevent damage during transportation.
Ensure that you have the following parts and tools available to pack the switch:
Phillips (+) screwdriver, number 2 (not provided)
The original switch packing material (cardboard box, accessory box and its contents, and foam padding)
ESD grounding strap
Antistatic bag
Do not pack the switch in anything except its original container to prevent damage during transit.
To pack the switch:
- If the switch is installed in a rack or cabinet, have one person support the weight of the switch while another person unscrews and removes the mounting screws.
- Remove the switch from the rack or cabinet, and place the switch on a flat, stable surface.
- Use the screwdriver to remove the rack-mounting brackets from the switch chassis.
- Place the switch in an antistatic bag.
- Place the bottom portion of the packaging foam in the shipping carton.
- Place the switch inside the cavity in the bottom packaging foam.
- Place the top portion of the packaging foam on top of the switch.
- If you are returning accessories or field-replaceable units (FRUs) with the switch, pack them as instructed in Packing EX4650 Switch Components for Shipping.
- Place the accessory box vertically by the rear end of the chassis in the shipping 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.
Packing EX4650 Switch Components for Shipping
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 that the component is adequately packed to prevent damage during transit. The packing material that 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 does not move inside the box.
- Securely tape the box closed.
- Write the RMA number on the exterior of the box to ensure proper tracking.
