Taking the Rear Card Offline in a QFX3008-I Interconnect Device


To prevent data loss, we recommend that you take a rear card offline and power it off before removing it from a QFX3008-I Interconnect device.

The rear cards provide switching functionality for a QFX3000-G QFabric system. We recommend that you install all eight rear cards in each QFX3008-I Interconnect device for normal device operation. When you take a rear card offline, the switching capacity of the QFX3000-G QFabric system will be reduced until the rear card is replaced.

To take the rear card offline in a QFX3008-I Interconnect device:

  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 interconnect-devices command.

    The card must show as connected and configured in order to have an orderly shutdown.

  3. Issue the request fabric administration power-off interconnect-device serial-id |alias-name fpc slot 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. Use the name of the Interconnect device in which the rear card you want to remove is installed, and the number of the slot from which you are removing the rear card; the slots are numbered from 8 through 15. See Slot Numbering for a QFX3008-I Interconnect Device.

    You see output similar to the following after entering the command:


    The final output of the request fabric administration power-off interconnect-devices serial-id |alias-name fpc slot CLI 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 Removing a Rear Card from a QFX3008-I Interconnect Device.
