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 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.
•
No other commands but the test diag-offline command can be executed for an isolated card.
Otherwise, the configuration cannot take effect. After isolating a card, you can use the test
diag-offline command to collect the fault detection information of the card. The path where the fault
detection information is saved is also displayed following the fault detection information on the
terminal. For example, you can see flash:/diag_slot3_20080522_103458.txt.
•
Deliver the fault detection information to the H3C technical engineers or engineers of the sales
agent.
