Returning the Chassis or Components

Locating the Serial Number on a QFX10002 or Component

If you are returning a switch or 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 a Return Materials Authorization (RMA). S

If the switch is operational and you can access the command-line interface (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 switch or component.


If you want to find the serial number ID label on a component, you need to remove the component from the switch chassis, for which you must have the required parts and tools available.

Listing the Chassis and Component Details Using the CLI

To list the QFX10002 and components and their serial numbers, use the show chassis hardware CLI operational mode command.


You must remove the fan module to read the fan serial number from the serial number ID label. The fan module serial number cannot be viewed through the CLI. Fan Tray 2 refers to the third module from the left, counting from 0.

Locating the Chassis Serial Number ID Label on a QFX10002 Switch

The serial number ID label is located on a label on the top cover.

Locating the Serial Number ID Labels on FRU Components

The power supplies and fan modules installed in a QFX10002 are field-replaceable units (FRUs). For each FRU, you must remove the FRU from the switch chassis to see the FRU serial number ID label.

  • AC power supply—The serial number ID label is on the top of the AC power supply.

  • Fan module—The serial number ID label is on the top of the fan module.

Removing the Solid State Drives for RMA

The QFX10002 has two solid-state drives (SSDs) that store the software images, system logs, and the configuration files. Before returning a chassis to Juniper Networks as part of a Return Merchandise Authorization (RMA), you have the option of removing the SSDs and disposing them according to your own company’s security procedures. Before you begin this procedure, ensure you have the following tools:

  • ESD grounding strap (not provided)

  • Number 2 Phillips screwdriver

Use this optional procedure to remove the drives from the QFX10002 after the device has shutdown and removed from the rack or cabinet.

  1. Attach the ESD grounding strap to your bare wrist and to a site ESD point.
  2. Place the device on a firm surface such as a workbench or a table.
  3. Using the number 2 Phillips screwdriver, remove the six flat-head screws that secure the access door on the right-side of the device. Retain the screws for later use.

  6. Replace the two thumbscrews and hand-tighten.
  7. Replace the six flat-head screws and hand tighten using the number 2 Phillips screwdriver.
  8. Dispose of the SSDs according to your site security procedures.

Returning a QFX10002 or Component for Repair or Replacement

If you need to return a QFX10002 or component to Juniper Networks for repair or replacement, follow this procedure:

  1. Determine the serial number of the component. For instructions.
  2. Obtain a Return Materials Authorization (RMA) number from the Juniper Technical Assistance Center (JTAC) as described in Contact Customer Support.

    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.

  3. Pack the switch or component for shipping.

Packing a QFX10002 or Component for Shipping

If you are returning a QFX10002 or component to Juniper Networks for repair or replacement, pack the item as described in this topic.

Before you pack a QFX10002 or component:

  • Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.

  • Retrieve 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.

Ensure that you have the following parts and tools available:

  • ESD grounding strap.

  • Antistatic bag, one for each component.

  • If you are returning the chassis, an appropriate screwdriver for the mounting screws used on your rack or cabinet.

Packing a QFX10002 Switch for Shipping

To pack a QFX10002 for shipping:

  1. Power down the switch and remove the power cables. See Powering Off a QFX10002.
  2. Remove the cables that connect the QFX100002 to all external devices.
  3. Remove all field-replaceable units (FRUs) from the device.
  4. Position a mechanical lift under the device. If a mechanical lift is not available, have two people support the weight of the switch while another person uses the screwdriver to remove the front mounting screws that attach the chassis mounting brackets to the rack or cabinet.
  5. Remove the switch from the rack or cabinet (see QFX10002 Installation Safety Guidelines) and place the switch in an antistatic bag.
  6. Place the switch in the shipping carton.
  7. Place the packing foam on top of and around the switch.
  8. If you are returning accessories or FRUs with the switch, pack them as instructed in Packing a QFX10002 or Component for Shipping.
  9. Replace the accessory box on top of the packing foam.
  10. Close the top of the cardboard shipping box and seal it with packing tape.
  11. Write the RMA number on the exterior of the box to ensure proper tracking.

Packing QFX10002 Switch Components for Shipping


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 and ship QFX10002 switch 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.
