I/O Process Error Alarm

This alarm is generated when the connection between a WAN subsystem input/output

process (IOP) and the SWAN concentrator is not operational.

To recover from this alarm, perform Steps 2 through 5 as described for SWAN

Download Error Alarm on page 1-7.

SWAN Memory Error Alarm

This alarm is generated when a checksum or memory error occurs.

To recover from this alarm, you must reboot the SWAN kernel by power-cycling the

SWAN concentrator.

Hardware Error Alarm

This alarm is generated when there is a problem with the battery, the power-on

self-test (POST) fails, the fan in the SWAN concentrator stops rotating, or the power

supply in the SWAN concentrator is not operational.

IOP Line Parameters Error Alarm

This alarm is generated when one or more of the attributes for a WAN subsystem

device (DEVICE object) is set to an invalid or out-of-range value, or if conflicting

attributes are configured.

To recover from this alarm, verify that the WAN subsystem devices are configured

correctly, and correct any WAN subsystem device configuration errors.

SWAN Kernel Error Alarm

This alarm is generated when a problem is detected in the SWAN firmware on the

SWAN concentrator. This alarm can indicate:

•

The CLIP was not in STOPPED state when you tried to execute the OSM or TSM

Test Verify action.

•

The SWAN firmware object code file (specified by the KERNELCODE attribute)

could not be downloaded to the SWAN concentrator.

•

The SWAN firmware needs to be updated.

Note. If you do not know the names of the WAN subsystem devices that use the SWAN

concentrator, use the SCF STATUS SERVER command. For more information, see the WAN

Subsystem Configuration and Management Manual.
