Installing the SSP
Troubleshooting the Installation
This section contains procedures to follow if the system does not restart and boot as expected.
Review the descriptions that follow, so you can anticipate the expected system startup sequence.
Then restart the system and try to isolate the problem by observing the LEDs as the system attempts
to boot the software and initialize the SSP and each interface processor.
The troubleshooting procedures in this section assume that your system was operating correctly up
until the time you install or replace the SSP and that any problems are a result of the newly installed
or upgraded SSP.
If the troubleshooting procedures indicate a problem with the power subsystem or one of the
interface processor cards, refer to the Cisco 7000 Hardware Installation and Maintenance or
Cisco 7010 Hardware Installation and Maintenance publications for complete system startup
troubleshooting procedures.
Verifying LEDs
Following are functional descriptions of the LEDs on the power supplies and processor modules, and
the behavior you should observe at system startup.
System Power LEDs
Cisco 7000 series models have a system power LED that should go on and stay on when the system
power is turned on. If the LED does not go on or stay on, there is most likely a problem with the
input power or one of the internal DC lines.
On the Cisco 7010, the system power LED is located on the lower right of the interface processor
end of the chassis and is labeled DC OK. (See Figure 3.) The rocker-type power switch turns the
power supply on and starts the system.
On the Cisco 7000, which operates with either one or two power supplies, the system power LEDs
are labeled and located on the individual power supplies. Each supply contains AC (or DC) power
and DC fail LEDs and a power switch. (See Figure 7.) When you turn on a power supply, the green
power LED should go on. The yellow DC fail LED should remain off. The power LED will not go
on if the power supply switch is not fully in the ON (|) position, or if the power supply is not properly
seated in the bay.
In both models, the power LED will not go on or will go off if the power supply reaches an
out-of-tolerance temperature or voltage condition. The power supply is unlikely to shut down during
startup because of an overtemperature condition; the power supply can, however, shut down if the
power supply detects an over- or under-voltage condition during startup.
For descriptions of environmental monitoring functions, refer to the Cisco 7000 Hardware
Installation and Maintenance or the Cisco 7010 Hardware Installation and Maintenance
publications.
