Chapter 7 Troubleshooting the Installation
Using debug Commands
Using debug Commands
Along with the other debug commands supported on the Cisco 10000 series router, you can obtain
specific debug information for the SIP on the Cisco
10000 series router using the debug hw-module
privileged EXEC command. The debug hw-module command is intended for use by Cisco Systems
technical support personnel.
Caution Because debugging output is assigned high priority in the CPU process, it can render the system
unusable. For this reason, use debug commands only to troubleshoot specific problems or during
troubleshooting sessions with Cisco technical support personnel. Moreover, it is best to use debug
commands during periods of lower network traffic and fewer users. Debugging during these periods
decreases the likelihood that increased debug command processing overhead will affect system use.
For more information about other debug commands supported on the Cisco 10000 series router, refer to
the Cisco IOS Command Reference publication for your Cisco IOS software release.
SPA Is Deactivated
Possible Problem Observations and Comments Solutions
SPA is not fully seated in the
SIP
Output of the show diag slot
command
SPA STATUS LED is off
Follow this procedure:
• Remove the SPA from the SIP.
• Inspect the SIP and the SPA. Verify there are no bent
pins or parts and that there is nothing lodged in the two
devices that could prevent a good connection.
• Insert the SPA in the SIP by sliding the SPA all the way
into the SIP until the SPA is firmly seated in the SPA
interface connector. When fully seated in the SIP, the
SPA might be slightly behind the SIP faceplate.
SPA is not supported on the
SIP

Follow the FPD upgrade process to update the FPGA.
For more information about performing FPD upgrades,
refer to the “Upgrading Field-Programmable Devices”
chapter in the Cisco
10000 Series Router SIP and SPA
Software Configuration Guide.
SPA is misconfigured Output of the show log
command
Refer to the configuration section of the specific SPA
software configuration guide, or use the Cisco IOS
software configuration documentation listed in the
