Contact a service representative.
•
One or more fans are not
operating.
•
The fans are operating too
slowly.
•
The power supply is not
operating.
To determine if the fans are
operating, listen for them. In noisy
environments, place your hand on
the rear of the chassis to feel if air
is being forced out the vents.
System shuts down, some fans may
or may not continue to rotate, 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.
•
Identify and log the failed fan
PEM location.
•
Replace the PEM.
Fan speed dropped below the fan
fail speed.
Multiple fan failure
Move other equipment or the router
to ensure proper airflow.
Heated exhaust air from other
equipment is entering the routers
inlet vents.
Contact a service representative.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.
System shuts down, and the
following error message is
displayed:
Queued messages:
%ENVM-1-SHUTDOWN:
Environmental Monitor
initiated shutdown
This error message indicates that
the system has detected an
over-temperature condition or
out-of-tolerance power condition
inside the chassis.
The system fans may
continue to operate
although the system shuts
down.
Note
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.
If an environmental shutdown
results from an out-of-tolerance
power condition, the system shuts
down.
