Troubleshooting Using Cisco PGW 2200 Softswitch Alarms
FAIL
This alarm occurs when the component referenced in the alarm failed. The failure might affect service,
in which case, the system raises other alarms.
Corrective Action
To correct the problem, perform the following steps:
Step 1 To collect system data, see the method that is described in the “Collecting System Data for Cisco TAC”
section on page 6-93.
Step 2 If the component identified in the alarm text is in the system software, contact the Cisco TAC to analyze
the problem further and to determine a solution. For more information about contacting the Cisco TAC,
see the “Obtaining Documentation and Submitting a Service Request” section on page xviii.
If the component identified in the alarm text is a component of system hardware, proceed to Step 3.
Step 3 Shut down the Cisco PGW 2200 Softswitch software on your standby Cisco PGW 2200 Softswitch, as
described in the “Shutting Down the Cisco PGW 2200 Softswitch Software Manually” section on
page 2-4.
Step 4 Restart the Cisco PGW 2200 Softswitch software on your standby Cisco PGW 2200 Softswitch, as
described in the “Starting the Cisco PGW 2200 Softswitch Software” section on page 2-2.
Step 5 Perform a manual switchover, as described in the “Performing a Manual Switchover” section on
page 3-96.
Caution Switchover operations cause the loss of all SS7 messages that are sent to the Cisco PGW 2200 Softswitch
for approximately three seconds. The switchover affects unstable in-progress calls as well as new calls.
Stable in-progress calls are not affected.
Step 6 Shut down the Cisco PGW 2200 Softswitch software on the newly standby Cisco PGW 2200 Softswitch,
as described in the “Shutting Down the Cisco PGW 2200 Softswitch Software Manually” section on
page 2-4.
Step 7 Restart the Cisco PGW 2200 Softswitch software on the newly standby Cisco PGW 2200 Softswitch, as
described in the “Starting the Cisco PGW 2200 Softswitch Software” section on page 2-2.
If that resolves the problem, the procedure is complete. Otherwise, proceed to Step 8.
Step 8 Replace the component that is identified in the alarm text. You can find procedures for replacing Cisco
PGW 2200 Softswitch hardware in the associated Sun Microsystems documentation. For procedures to
replace Cisco ITP-L hardware, see the documentation for the
Cisco 2800 Series Integrated Services Routers. Find procedures for replacing Cisco switch hardware in
the documentation for the switch.
Step 9 Contact the Cisco TAC to analyze the problem further and to determine a solution. See the “Obtaining
Documentation and Submitting a Service Request” section on page xviii.
