Troubleshooting Installation Issues
SCP Download Failures • A line card is reset by the SP with messages
that SCP download failed or module reloaded
during reset. This occurs at the time of bootup
with a heavy configuration and a many line
cards. Execute the debug cwan oir command
to check the RP status. When a line card sends
a Find Master to the RP, some of the messages
are sent to SP to confirm if the module is
online. If the message fails to reach the SP,
then SP resets the module with message that
SCP download has failed. If the line card,
does not receive the response in the time, the
line card resets itself.
• Reload the line card and connect the LC
console and check the status. If there is a
problem with ROMMON download of the
image from the SP, then the ROMMON of the
line card should then be upgraded to the latest
version. If a bay crashes, collect the stack
trace to identify problem.

An SCP ping is sent every two seconds to all the
line cards. If no response is received after three
pings (that is after 6 seconds), it is counted as the
first failure. After 25 such successive failures, that
is after 150 seconds of not receiving a response
from the line card, the SUP power cycles that line
card. After every 30 seconds, the following error
message is seen on the router:
%CPU_MONITOR-SP-6-NOT_HEARD:
CPU_MONITOR messages have not been
heard for 61 seconds [2/0]
%CPU_MONITOR-SP-6-NOT_HEARD:
CPU_MONITOR messages have not been
heard for 151 seconds [2/0]
After 150 seconds, the module gets power cycled
with these syslogs:
%CPU_MONITOR-SP-3-TIMED_OUT:
CPU_MONITOR messages havefailed,
resetting module [2/0]
%OIR-SP-3-PWRCYCLE: Card in module
