Incorrect Logical Configuration Alarm
To recover from this alarm:
1. Stop the CLIP and retry the Test Verify action. For more information, see Preparing
a SWAN CLIP for the OSM or TSM Test Verify Test Action or Firmware Update on
page 4-19.
2. Try to clear the alarm.
If the alarm persists:
1. Determine if the problem is related to Firmware and Battery Problems on page 4-3.
2. Make sure that the SWAN firmware object code file is secured with "N" read
access. The SWAN firmware object code file should be located in the
$SYSTEM.CSSnn subvolume.
3. Make sure that the TFTP server process is configured to use the correct location
for the SWAN firmware object code file. (The TFTP server is automatically
configured by the WAN manager process.) The location of download files is
specified by the STARTUP attribute. (The default location is $SYSTEM.CSSnn.)
4. Run the Test Basic Online test action on the communications line interface
processor (CLIP) that generated the alarm.
5. Update the SWAN firmware, if necessary. You can update SWAN firmware by
using the OSM Service Connection or the TSM Service Application. For more
information, see the online help within each application or the SWAN manual for
your type of concentrator (for example, the SWAN 2 Concentrator Installation and
Support Guide). ..
Incorrect Logical Configuration Alarm
This alarm is generated when the SWAN concentrator is incorrectly configured or when
a WAN subsystem process or supporting process or object (such as a TCP/IP process,
SUBNET, or LIF) is not operational.
If you need more information about correcting a configuration problem, see Correcting
SWAN Concentrator Configuration Errors on page 2-5. If you need more information
about starting a required process or object, see the WAN Subsystem Configuration
and Management Manual.
To recover from this alarm:
1. Verify that the SWAN concentrator is configured correctly.
2. Correct any configuration errors.
Note. You must stop the CLIP you are testing and shut down any active communications lines
that are using the CLIP before you update its firmware using the TSM Service Application. For
more information, see Preparing a SWAN CLIP for the OSM or TSM Test Verify Test Action or
Firmware Update on page 4-19.
