Chapter 6 Troubleshooting the Cisco PGW 2200 Softswitch Platform
Platform Troubleshooting
Step 6 Re-install the operating system as described in
Cisco PGW 2200 Softswitch Release 9.8 Software Installation and Configuration Guide. Select the
64-bit kernel during installation.
If the operating system installs successfully, proceed to Step 7. Otherwise, proceed to Step 9.
Step 7 Repeat Step 5 to ensure that the 64-bit kernel is installed.
If the 64-bit kernel is installed, proceed to Step 8. Otherwise, proceed to Step 9.
Step 8 Re-install the Cisco PGW 2200 Softswitch software according to the instructions in
Cisco PGW 2200 Softswitch Release 9.8 Software Installation and Configuration Guide.
If the Cisco PGW 2200 Softswitch software installs successfully, proceed to Step 10. Otherwise, proceed
to Step 11.
Step 9 Your system hardware is unable to support the 64-bit kernel. To operate the Cisco PGW 2200 Softswitch
software, the 64-bit kernel must be installed. You must upgrade your hardware to enable your system to
support the 64-bit operating system. For instructions on upgrading your hardware, see the Sun
Microsystems documentation for the host platform.
After the upgrade is complete, repeat this procedure starting from Step 6. If the hardware upgrade
resolves the problem, proceed to Step 10. Otherwise, proceed to Step 11.
Step 10 Repeat the preceding steps on the other Cisco PGW 2200 Softswitch in your system.
If the problem is resolved after fixing both Cisco PGW 2200 Softswitches, the procedure is complete.
Otherwise, proceed to Step 11.
Step 11 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.
Correcting the System Time
Note Configure the Cisco PGW 2200 Softswitches to use NTP to maintain system time according to the
instructions in Cisco PGW 2200 Softswitch Release 9.8 Software Installation and Configuration Guide.
If you detect instances when the system time is incorrect, you can correct it. System time can vary
depending on how system time was set on your system, and whether the Cisco PGW 2200 Softswitch
records call detail records (CDRs). The following procedures explain how to correct system time:
• NTP is Not Used and the Cisco PGW 2200 Softswitch is Not the Source of the CDRs, page 6-186
• NTP is Not Used and Cisco PGW 2200 Softswitch is the Source of the CDRs, page 6-186
• NTP is Used and the Cisco PGW 2200 Softswitch is the Source of the CDRs, page 6-187
Caution It is critically important to synchronize the host system clock in a manner that does not adversely affect
operating system or application processes. A rapid change of the system clock can adversely affect call
processing, system logs, and CDRs.
