Reporting Functions - Cisco 7206 - VXR Router Installation Manual

Chapter 1 Product Overview
Functional Overview
The low warning and high warning ranges in Table 1-11 are informational and if a low warning or high
warning message appears, the warning message does not signify that an error or hazard is occurring. A
high warning message sometimes appears in a lightly loaded chassis, especially if the router is running
without port adapters or with dual power supplies. Adding current load to the router may remove the
warning; this can easily be achieved by installing one or more port adapters.
Below are sample high warning messages from chassis with 3V and 5V power supplies:
Router(boot)#
00:00:44:%ENVM-4-ENVWARN:+3.45 V measured at +3.57
Router(boot)#
00:04:49:%ENVM-4-ENVWARN:+5.15 V measured at +5.33
Low critical or high critical warning messages should be addressed immediately through the normal field
Note
support procedures.
Below are sample high critical messages from chassis with 3V and 5V power supplies:
Router(boot)#
00:02:47:%ENVM-2-ENVCRIT:+3.45 V measured at +3.66
Router(boot)#
00:06:51:%ENVM-2-ENVCRIT:+5.15 V measured at +5.47

Reporting Functions

The Cisco 7206 displays warning messages on the console if chassis interface-monitored parameters
exceed a defined threshold. You can also retrieve and display environmental status reports with the show
environment, show environment all, show environment last, and show environment table
commands. Parameters are measured and reporting functions are updated every 60 seconds. A brief
description of each of these commands follows.
To prevent overheating the chassis, ensure that your system is drawing cool inlet air. Overtemperature
Caution
conditions can occur if the system is drawing in the exhaust air of other equipment. Ensure adequate
clearance around the sides of the chassis so that cooling air can flow through the chassis interior
unimpeded and exhaust air exits the chassis and is not drawn into the inlet vent of another device.
The show environment command display reports the current environmental status of the system. The
report displays parameters that are out of the normal values. No parameters are displayed if the system
status is normal. The example that follows shows the display for a system in which all monitored
parameters are within normal range:
Router# show environment
All measured values are normal
If the environmental status is not normal, the system reports the worst-case status level. Following is a
sample overvoltage warning:
Router# show environment
Warning: +3.45 V measured at +3.83 V
