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

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

The rear cards provide switching functionality for a QFX3000 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 QFabric system will be reduced until the rear card is replaced.

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

1. Use the request chassis fpc interconnect-device name slot slot-number offline CLI command. Enter the name of the 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.
2. Use the show chassis fpc CLI command to verify that the rear card is offline. When the state field in the command output shows that the card is offline, it is safe to remove the rear card. See Removing a Rear Card from a QFX3008-I Interconnect Device.
