Return a QFX5240 Chassis or Components

Locate the Serial Number on a QFX5240 Device or Component

If you are need to return 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 this serial number to the Juniper Networks Technical Assistance Center (JTAC) when you contact them to obtain a 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 switch or component.

Note:

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.

List the Chassis and Component Details Using the CLI

To list the switch and components and their serial numbers, use the show chassis hardware CLI operational mode command. The following output lists the switch components and serial numbers for a QFX5240 switch. The output is similar for other QFX5240 switches:

Note:

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.

Locate the Chassis Serial Number ID Label on a QFX5240 Switch

You can find the chassis serial number in either the show chassis hardware command output or physically on a pull-out tab located on the right side of the QFX5240 port panel. See Figure 1 for the QFX5240-64OD Switch and Figure 2.

Locate the Serial Number ID Labels on FRUs in a QFX5240 Switch

The power supplies and fan modules installed in a QFX5240 switch 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. Figure 3 shows the location of the serial number ID label on the AC power supply for QFX5240 switches.

  • Fan module—The serial number ID label is on the bottom of the fan module for QFX5240 switches. Figure 4 shows the location of serial number on QFX5240 switches. The serial number ID label is on the side of the fan module for QFX5240-48C switches.

Remove the Solid-State Drives for RMA on QFX5240 Switches

The QFX5240 switches have 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 Material 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 strip (not provided)

  • Phillips screwdriver, number 2

Use this optional procedure to remove the drives from the QFX5240 switches after the device has shut down and you’ve removed it from the rack or cabinet. The SSD doors are located on the top of the QFX5240 switch.

  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 with the SSD doors facing up.
  3. Use the Phillips screwdriver to remove the three flat-head screws from each door on the top of the device. See Figure 5.
    Figure 5: Remove Screws on SSD Doors for a QFX5240 Switch Remove Screws on SSD Doors for a QFX5240 Switch
  4. Remove the doors and set aside the screws.
  5. Use the Phillips screwdriver to remove the screw on one of the SSDs and set it aside. See Figure 6.
    Figure 6: Removing the Screw and Lifting the SDD Out Removing the Screw and Lifting the SDD Out
  6. Lift the end furthest from the connector and remove from the cavity. Repeat Step 5 and Step 6.
  7. Replace the screws and hand-tighten the screws using the Phillips screwdriver.
  8. Replace the SSD doors and the six flat-head screws. See Figure 7.

  9. Hand-tighten the screws using the Phillips screwdriver.
  10. Dispose of the SSDs according to your site security procedures.
