Returning an EX3300 Switch or Component for Repair or Replacement
If you need to return an EX3300 switch or hardware component to Juniper Networks for repair or replacement, follow this procedure:
- Determine the serial number of the component. For instructions, see Locating the Serial Number on an EX3300 Switch or Component.
- Obtain an RMA number from JTAC as described in Contact Customer Support to Obtain Return Material Authorization.
Note Do not return any 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.
- Pack the switch or component for shipping as described in Packing an EX3300 Switch or Component for Shipping.
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 EX3300 Switch or Component
If you are returning an EX3300 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 (see Figure 1) 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 with the CLI
To list the switch and switch components and their serial numbers, enter the following CLI command:
user@switch> show chassis hardware
Hardware inventory: Item Version Part number Serial number Description Chassis GB0210504152 Virtual Chassis Routing Engine 0 REV 02 750-034250 GB0210504155 EX3300 48-Port POE+ Routing Engine 1 REV 02 750-034250 GB0210504152 EX3300 48-Port POE+ FPC 0 REV 02 750-034250 GB0210504155 EX3300 48-Port POE+ CPU BUILTIN BUILTIN FPC CPU PIC 0 BUILTIN BUILTIN 48x 10/100/1000 Base-T PIC 1 REV 02 750-034250 GB0210504155 4x GE/XE SFP+ Xcvr 0 REV 01 740-021308 63152A01393 SFP+-10G-SR Xcvr 1 REV 01 740-030658 AD0946A01Z6 SFP+-10G-USR Power Supply 0 PS 900W AC Fan Tray Fan Tray FPC 1 REV 02 750-034250 GB0210504152 EX3300 48-Port POE+ CPU BUILTIN BUILTIN FPC CPU PIC 0 BUILTIN BUILTIN 48x 10/100/1000 Base-T PIC 1 REV 02 750-034250 GB0210504152 4x GE/XE SFP+ Xcvr 0 REV 01 740-021308 AJP0NRC SFP+-10G-SR Xcvr 1 REV 01 740-021308 AJN0CXF SFP+-10G-SR Xcvr 2 REV 01 740-021308 63152A00952 SFP+-10G-SR Xcvr 3 REV 01 740-021308 63152A00753 SFP+-10G-SR Power Supply 0 PS 900W AC Fan Tray Fan Tray
Locating the Chassis Serial Number ID Label on an EX3300 Switch
EX3300 switches have serial number ID labels located on the rear panel of the chassis (see Figure 1).

Packing a Switch for Shipping
To pack a switch for shipping:
- 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 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 the switch is mounted on a wall or on two posts, have one person support the weight of the switch while another person unscrews and removes the mounting screws. Use the Phillips (+) screwdriver to remove the screws.
- Remove the switch from the wall, rack, cabinet, or desk and place the switch in an antistatic bag.
- Slip on the end caps of the packaging foam on both sides of the switch.
- Place the switch in the shipping carton.
- Place the packing foam on top of and around the switch.
- If you are returning accessories or FRUs with the switch, pack them as instructed in Packing Switch Components for Shipping.
- Close the top of the cardboard carton and seal it with packing tape.
- Write the RMA number on the exterior of the carton to ensure proper tracking.
Packing Switch Components for Shipping
To pack and ship switch components:
Place individual components 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 carton and seal it with packing tape.
Write the RMA number on the exterior of the carton to ensure proper tracking.
