Isolating a card

When a card fails or an interface card's CPU daughter card logic needs to be upgraded, you can isolate
the card from the system, so the card stops providing services without affecting the system operation and
the services on other cards.
An isolated card is in offline state. You can use the display device command to verify the status.

Isolation guidelines

The active MPU cannot be isolated.
The last switching fabric card in a device cannot be isolated.
You cannot perform an ISSU when one or more cards are isolated.
Do not perform configurations for an isolated card. The configurations might not be able to take effect.
To eliminate possible impact on the system, HP recommends you isolate a switching fabric card before
removing it.
