14.3.1 Error Location and recovery processing

Error detected at a port

Automatic recovery of the applicable port is performed six times per hour. If a failure occurs at the sixth auto-recovery attempt, the switch stops. #However, if the system is operated for one hour or more after the first failure, the automatic recovery count is initialized.

Re-initializes the affected port.

Communication via the affected port is suspended.

Main board (CPU) failure

Makes auto-recovery attempts up to six times. If a failure occurs at the sixth auto-recovery attempt, the switch stops. The number of auto-recovery attempts are reset after one hour of post recovery operation.

Re-initializes the main board.

For the sixth automatic recovery, the running-config is initialized and VLAN status is set to disable to start.

Communication via all ports on the switch is suspended.

Main board (SW) failure

Makes six auto-recovery attempts in one hour. If a failure occurs at the sixth auto-recovery attempt, the switch stops. #However, if the system is operated for one hour or more after the first failure, the automatic recovery count is initialized.

Re-initializes the switching processor.

Communication via all ports on the switch is suspended.

Power supply (PS) failure

Stops when the power required to run the switch ceases to be supplied. Keeps running if power redundancy has been configured.

Stops the switch. Keeps running if power redundancy has been configured.

Communication via all ports on the switch is suspended. If the redundant power supply unit is used, communication is not suspended.

Fan failure

Increases the speed of the other fan.

There is no means of auto-recovery. Replace the power supply unit or failed fan unit.

The other fan runs faster, but this does not affect communications.
