Isolating a card

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 while causing
no interference on the operation of the system and services of other cards.
Configuration restrictions and guidelines
The active MPU cannot be isolated.
If only one switching fabric module is working on the switch, it cannot be isolated.
Before upgrading a logic of the LPU, keep the LPU offline.
To minimize the interference on the system operation, force a switching fabric module that is
operating normally offline before you unplug it.
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 other configurations on the isolated card.
Configuration procedure
To isolate a card:
In standalone mode:
Slot—A number in this field indicates a card.
In IRF mode:
Slot—The chassis-number/slot-number in this field
indicates a card on an IRF member switch.
Temperature sensor:
hotspot—Hotspot sensor.
inflow—Air inlet sensor.
outflow—Air outlet sensor.
Current temperature.
Lower temperature threshold.
Warning temperature threshold.
Alarming temperature threshold.
Shut-down temperature threshold (currently not supported).
