Power supply shutdown
—
The power supply detected an internal out-of-tolerance overvoltage, overcurrent,
or temperature condition and shut itself down. All DC power remains disabled until you toggle the power
switch.
The Cisco ASR 1001-X Router does not shut down automatically during an over-temperature condition. The
router will remain active irrespective of what the ambient temperature is, if the router is exposed to an extremely
hot environment for a prolonged period of time, it will remain active until the hardware fails.
The
facility-alarm critical exceed-action shutdown
command is disabled on the Cisco ASR 1001-X Router.
The console terminal displays the following error message if you execute the
facility-alarm critical
exceed-action shutdown
command:
Router(config)#

Fan Failures
Four internal fans draw cooling air into the chassis and across internal components to maintain an acceptable
operating temperature. The fans are located in the center of the chassis. The fans are numbered from 0 to 3,
right to left. When the system power is on, all fans should be operational. However, the system continues to
operate even if a fan fails.
Use the
show platform hardware slot <slot> fan status
command to view the status of the fans, for example:
