Remove a QFX5100 Device

Installing and Removing QFX5100 Device Hardware Components

The QFX5100 switch chassis is a rigid sheet-metal structure that houses the hardware components. The field-replaceable units (FRUs) in QFX5100 devices are:

  • Power supply

  • Fan module

  • Expansion module (QFX5100-24Q and QFX5100-24Q-AA only)

  • SFP+ transceiver

  • QSFP+ transceiver

All of the QFX5100 device FRUs are hot-insertable and hot-removable: you can remove and replace them without powering off the switch or disrupting switch functions.

CAUTION:

Replace a failed power supply with a new power supply within 1 minute of removal to prevent chassis overheating. Replace a failed fan module with a new fan within 1 minute of removal to prevent chassis overheating.

To install a power supply in a QFX5100 device, follow the instructions in Installing a Power Supply in a QFX5100 Device. To remove a power supply from a QFX5100 device, follow the instructions in Removing a Power Supply from a QFX5100 Device.

To install a fan module in a QFX5100 device, follow the instructions in Installing a Fan Module in a QFX5100 Device. To remove a fan module from a QFX5100 device, follow the instructions in Removing a Fan Module from a QFX5100 Device.

To install an SFP+ or QSFP+ transceiver in a QFX5100 device, follow the instructions in Installing a Transceiver in a QFX Series Device. To remove an SFP+ or QSFP+ transceiver from a QFX5100 device, follow the instructions in Removing a Transceiver from a QFX Series Device.

To connect a fiber-optic cable to an SFP+ or QSFP+ transceiver in a QFX5100 device, follow the instructions in Connecting a Fiber-Optic Cable to a QFX Series Device. To disconnect a fiber-optic cable from an SFP+ or QSFP+ transceiver from a QFX5100 device, follow the instructions in Disconnecting a Fiber-Optic Cable from a QFX Series Device.

Powering Off an Existing QFabric Node Device

Use this procedure to gracefully shut down an existing device in a server Node group, redundant server Node group, or network Node group. This orderly process reduces traffic loss on server Node devices and prevents traffic loss on redundant server Node devices and network member devices.

CAUTION:

Do not use the request system halt command to shut down an existing Node device or traffic loss can occur.

  1. Log into the QFabric default partition on the Director device and start the CLI.
  2. Discover the device connection status and the alias name (identifier) by issuing the show fabric administration inventory command.

    The Node device must show as connected and configured to have an orderly shutdown.

  3. Start the orderly shutdown of the Node device by issuing the request fabric power-off node-device operational mode command from the QFabric default partition CLI. This command systematically takes the node offline and gracefully shuts down the device while preserving system state information. A message appears on the console or console log, confirming that the operating system has stopped on the device.

    You see the following output after entering the command:

    CAUTION:

    The final output of the request fabric power-off node-device command is the following message: The device is shutting down and can be removed when the LCDs are off. Wait at least 3 to 4 minutes after first seeing this message before following the instructions in Step 5 and Step 6 to disconnect the switch.

  4. Attach the grounding strap to your bare wrist and to a site ESD point.
  5. Disconnect power to the switch by performing one of the following tasks:
    • AC power supply—If the AC power source outlet has a power switch, set it to the OFF (O) position. If the AC 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.

    • DC power supply—Switch the circuit breaker on the panel board that services the DC circuit to the OFF position.

  6. Remove the power source cable from the power supply faceplate:
    • AC power supply—Remove the power cord from the power supply faceplate by detaching the power cord retainer and gently pulling out the socket end of the power cord connected to the power supply faceplate.

    • DC power supply—Remove the screws securing the ring lugs attached to the power source cables to the power supply using the screwdriver, and remove the power source cables from the power supply. Replace the screws on the terminals and tighten them.

Removing a QFX5100 Device from a Rack or Cabinet

Before removing a QFX5100 device from a rack:

Ensure that you have the following parts and tools available:

  • A Phillips (+) screwdriver, number 2 or number 3, depending on the size of your rack mounting screws, for mounting the QFX5100 device on the rack.

If you need to relocate an installed QFX5100 device, use the procedure described in this topic. (The remainder of this topic uses “rack” to mean “rack or cabinet.” )

Note:

When you remove multiple devices from a rack, remove the device in the top of the rack first and proceed to remove the rest of the devices from top to bottom.

  • Ensure that the rack is stable and secured to the building.

  • Ensure that there is enough space to place the removed QFX5100 device in its new location and along the path to the new location.

  • Read General Safety Guidelines and Warnings.

  • Use the appropriate power off sequence for your configuration to safely powered off the device.

  • Disconnect the power cords.

  • Ensure that you have disconnected any cables or wires attached to the QFX5100 switch ports.

To remove a QFX5100 device from a rack or cabinet:

  1. Have one person 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.
  2. Remove the QFX5100 device from the rack or cabinet.
  3. Use the screwdriver to remove the mounting screws that attach the mounting blades attached to the rear of the rack or cabinet.
  4. Place the removed screws and mounting blades in a labeled bag. You will need them when you reinstall the chassis.
  5. Transport the QFX5100 device to your desired new location.
