Isolating a card and locating card faults

When the switch detects a card failure or upgrades a logic of the CPU daughter card on a card, you
can isolate the faulty card or the CPU daughter card to prevent it from forwarding data packets. This
operation allows for convenient on-site fault location or upgrading while causing no interference on
the operation of the system and services of other cards.

Configuration guidelines

•
The active MPU on a standalone switch or an IRF member switch cannot be isolated.
•
At least one operating switching fabric module cannot be isolated for a standalone switch or an
IRF member switch.
•
To minimize the interference on the system operation, force a switching fabric module that is
operating correctly offline before you unplug it.
•
ISSU is unavailable for offline cards.
•
You can use the display device command to view whether a card is isolated, or, whether the
card is in the offline state.
•
Do not perform configuration on an isolated card. Configuration on an isolated card might not
take effect.
