Adding or Replacing a QFX3008-I Interconnect Device in a QFX3000-G QFabric System

 

The Director group in a QFX3000-G 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. You can install up to four QFX3008-I Interconnect devices in a QFX3000-G QFabric system.

Before You Begin

Before you add or replace a QFX3008-I Interconnect device in a QFX3000-G 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 QFX3008-I Interconnect device and connect it to power to minimize the amount of time it will take to replace the device.

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

  • An ESD grounding strap

  • An external management device such as a PC

Powering Off a QFX3008-I Interconnect Device

To gracefully shut down a QFX3008-I Interconnect device on a QFX3000-G QFabric system:

  1. Log into the QFabric default partion 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 Interconnect device must show as connected and configured in order to have an orderly shutdown.

  3. Start the orderly shutdown of the QFX3008-I Interconnect device by issuing the request fabric power-off interconnect-device serial-id | alias-name operational mode command from the QFabric default partition CLI. This command systematically takes the interconnect 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 output similar to the following after entering the command:

    Caution

    The final output of the request fabric administration power-off interconnect-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 to power off the device.

  4. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
  5. Set the wiring tray switch to the OFF (O) position. Observe the wiring tray LEDs. The power supply LEDs should turn off (appear unlit). Repeat this step for the second wiring tray.
Note

After you power off a wiring tray, wait for at least 60 seconds before you turn it back on. After you power on a wiring tray, wait for at least 60 seconds before you turn it back off.

Note

The power supplies in a QFX3008-I Interconnect device continue to use a small amount of power when the C19 wiring tray power switch is in the off position. The status LEDs on each power supply blink amber because the power supply fans are not operating. This is expected behavior.

Adding a New QFX3008-I Interconnect Device to the QFabric System

To add a new QFX3008-I Interconnect device to the QFabric system:

  1. Install the new device and connect the QFX3008-I Interconnect device to power. See Installing and Connecting a QFX3008-I Interconnect Device for more information about mounting the device in a rack and connecting the device to power.
  2. Connect the new QFX3008-I Interconnect device to the QFX3000-G QFabric system control plane network. See Connecting a QFX3008-I Interconnect Device to a Copper-Based QFX3000-G QFabric System Control Plane Network or Connecting a QFX3008-I Interconnect Device to a Fiber-Based QFX3000-G QFabric System Control Plane Network.
  3. Power on the new QFX3008-I Interconnect device:

    1. Attach the ESD grounding strap to your bare wrist and connect the strap to the ESD point on the chassis.
    2. Ensure that the power supplies are fully inserted in the chassis.
    3. Ensure that the source power cords are installed correctly for each wiring tray, and the wiring trays are fully inserted in the chassis.
    4. Switch on the site circuit breakers.
    5. Set a wiring tray’s switch to the ON (|) position. Observe the power supply and wiring tray faceplate LEDs. If the wiring trays are installed correctly and functioning normally, the LEDs light green and remain constantly lit.
    6. Repeat Step e for the second wiring tray installed in the device.
  4. The QFabric system upgrades the QFX3008-I Interconnect device to the version of software installed on the QFX3100 Director devices. Verify that the QFX3008-I Interconnect device has been upgraded to the correct version of software using the show version component all operational mode command from the QFabric default partition CLI.Note

    It takes some time for the software upgrade to occur. Do not proceed to the next step until the show version component all command verifies that the software has been upgraded.

  5. Verify that the QFX3008-I Interconnect device has been added to the QFX3000-G QFabric system using the show fabric administration inventory interconnect-devices operational mode command from the QFabric default partition CLI.
  6. Write down the serial number of the new device from the output of the show fabric administration inventory interconnect-devices command.
  7. From the QFabric director, enter the following configuration mode CLI commands to remove the previous Interconnect device from the inventory of QFabric system components and associate the serial number of the new device with the alias of the previous device.
    root@fabric# delete fabric aliases interconnect-device old-serial-numberalias-name


    root@fabric# set fabric aliases interconnect-device new-serial-numberalias-name
  8. Commit the changes using the commit command, which sends the configuration of the old device to the new device.
  9. Connect the QFX3008-I Interconnect device to each Node device for data plane interconnection. See Connecting a QFX3600 Node Device to a QFX3008-I Interconnect Device or Connecting a QFX3500 Node Device to a QFX3008-I Interconnect Device.
  10. Verify the data plane interconnection using the show chassis fabric connectivity operational mode command from the QFabric default partition CLI. Repeat this command if necessary until the new device is shown in the output.
  11. Remove the previous QFX3008-I Interconnect device from the inventory of QFabric system components using the request fabric administration remove interconnect-device device-name operational mode command from the QFabric default partition CLI.
