Adding or Replacing a QFX3100 Director Device in a QFabric System

date_range 13-Sep-17

The Director group in a QFabric system automatically recognizes when devices are added or replaced in the QFabric system. The Director group sends each device its own portion of the Junos OS configuration and adds them to the QFabric system inventory.

Before you replace a QFX3100 Director device in a QFabric system:

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

  • If possible, install the replacement QFX3100 Director device and connect it to power to minimize the amount of time it takes to replace the device.

Ensure that you have the following parts and tools available to replace the device:

  • An ESD grounding strap

  • An external management device such as a PC

  • An RJ-45 to DB-9 rollover cable to connect the external management device to the console port

  • A 4-gigabyte (GB) USB flash drive

Powering Off and Removing the Old QFX3100 Director Device

If you are replacing a device, power off the QFX3100 Director device that you will remove from the QFabric system:

  1. Log in to the default partition of your QFabric system. See Gaining Access to the QFabric System Through the Default Partition.
  2. Shut down the Director device by issuing the request system halt director-device director-device-name operational mode CLI command. This command shuts down the device gracefully and preserves system state information. A message appears on the console, confirming that the operating system has halted.
  3. Observe the power supply faceplate LEDs. The AC power supply LED should turn off.
  4. Uncable the old QFX3100 Director device. Label each cable as you remove it, so that you can easily connect the replacement Director device.

Update the New QFX3100 Director Device Software

To update the new QFX3100 Director device software:

  1. Perform a recovery installation to upgrade the software to the same version that is on the existing Director device. See Performing a QFabric System Recovery Installation on the Director Group.
    Note

    You do not need to complete the steps to restore the backup configuration file. The Director device will receive the correct configuration from the other QFX3100 Director device.

  2. Shut down the Director device by issuing the request system halt director-device director-device-name operational mode CLI command. This command shuts down the device gracefully and preserves system state information. A message appears on the console, confirming that the operating system has halted.
  3. Observe the power supply faceplate LEDs. The AC power supply LED should turn off.

Adding the New QFX3100 Director Device to the QFabric System

To add a new QFX3100 Director device to the QFabric system:

  1. Install the new device and connect the QFX3100 Director device to power. See Installing and Connecting a QFX3100 Director Device for more information about mounting the device in a rack and connecting the device to power.
  2. Interconnect the two QFX3100 Director devices for control plane redundancy. See Connecting QFX3100 Director Devices in a Director Group.
  3. Connect the QFX3100 Director device to the control plane network. See Connecting QFX3100 Director Devices to a Copper-Based QFX3000-G QFabric System Control Plane Network, Connecting QFX3100 Director Devices to a Fiber-Based QFX3000-G QFabric System Control Plane Network, Connecting QFX3100 Director Devices to a Copper-Based QFX3000-M QFabric System Control Plane Network, or Connecting QFX3100 Director Devices to a Fiber-Based QFX3000-M QFabric System Control Plane Network.
  4. Power on the new Director device. The new Director device will synchronize its database with the existing Director device. See Powering On a QFX3100 Director Device for more information about powering on the Director device.
  5. Verify that the QFX3100 Director device has been added to the QFabric system using the show fabric administration inventory director-group status operational-mode CLI command from the QFabric default partition CLI.
