Fan Failures

When the system power is on, all fans should be operational. The system continues to operate if a fan
fails. When a fan fails, the system displays the following message:
router: 00:03:46:%ENVM-3-BLOWER:Fan 2 may have failed
If the air temperature exceeds a defined threshold, the system controller displays warning messages on
the console terminal, and if the temperature exceeds the shutdown threshold, the system controller shuts
down the system.
If the system does shut down because the temperature exceeded the shutdown threshold, the system
displays the following message on the console screen and in the environment display when the system
restarts:
Queued messages:
%ENVM-1-SHUTDOWN: Environmental Monitor initiated shutdown

Reporting Functions

The chassis manager on the forwarding engine control processor manages the local resources of the
forwarding processor. It manages the ESI (Enhanced Serdes Interconnect) which are the datapath links
on the midplane connecting the Cisco ASR 1000 Series RP1s, SIPs, and standby ESP modules to the
active Cisco ASR 1000 Series Embedded Services Processor. It communicates with the chassis manager
on the Cisco ASR 1000 Series Route Processor 1 to report the status and health, including detected
hardware failures, ESI status, software process status, and the state of thermal sensors.
The Cisco ASR 1000 Series Routers display warning messages on the console if chassis
interface-monitored parameters exceed a desired threshold. You can also retrieve and display
environmental status reports with the show environment all, show version, show inventory, show
platform, and show diag commands. Parameters are measured and reporting functions are updated
every 60 seconds. A brief description of each of these commands follows.
Note The example outputs displayed in this section are from a Cisco ASR 1004 Router. Similar output
displays for all Cisco ASR 1000 series routers.
OL-13208-03
Shutdown—The processor has detected a temperature condition that could result in physical damage
to system components and has disabled DC power to all internal components. This condition
requires immediate operator action. All DC power remains disabled until you toggle the power
switch. Before any shutdown, the system logs the status of monitored parameters in NVRAM so you
can retrieve it later to help determine the cause of the problem.
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.
