Chapter 7 Troubleshooting the Installation
Using debug Commands
Using debug Commands
The
debug hw-module subslot
command is intended for use by Cisco Systems technical support
personnel. For more information about the
debug hw-module subslot
command, see the
Cisco 7600
Series Router SIP, SSC, and SPA Software Configuration Guide
.
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 staff. 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.
SIP 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 7600 Series Router SIP, SSC, and SPA
Software Configuration Guide
.
SPA is misconfigured
Refer to the configuration section of the specific SPA
installation and configuration guide, or use the Cisco IOS
software configuration documentation listed in the
“Obtaining Documentation, Obtaining Support, and
Security Guidelines” section on page xii
