Troubleshooting the Shared Port Adapter
Check the following to help isolate a problem with the shared port adapter:
Heated exhaust air from other
equipment is entering the routers
inlet vents.
Move other
equipment or the
router to ensure
proper airflow.
System shuts down and this error message
is displayed:
Queued messages:
%ENVM-1-SHUTDOWN: Environmental
Monitor initiated shutdown
This error message indicates that the system
has detected an overtemperature condition
or out-of-tolerance power condition inside
the chassis.
Note The system fans may continue to
operate although the system shuts
down.
The error message could indicate a
faulty component or temperature
sensor. Before the system shuts
down, use the show env all command
to display the internal chassis
environment.
Contact a service
representative.
If an environmental shutdown results
from an out-of-tolerance power
condition, the system shuts down.
If the system still
fails to come up
when the power
supply is
connected to a
different power
source with a new
power cable, the
power supply is
probably faulty.
Contact a service
representative.

Shared Port
adapter
ENABLED
LED is off.
The shared port
adapter might
have pulled away
from the system
board.
Reseat the adapter in its slot (you do not have to turn off the
system power when removing or replacing port and service
adapters). After the system reinitializes the interfaces, the
ENABLED LED on the shared port adapter should go on.
If the ENABLED LED remains off, the system detected a
processor hardware failure. (This LED should be on in normal
operation.) Contact a service representative for instructions.
