Chapter 1 Overview
The show environment command displays 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: +3.3 V measured at +3.41 V
The show environment last command retrieves and displays the NVRAM log, which provides a record
of environmental status readings. Air temperature is measured and displayed, and the voltage supplied
by the power supply is also displayed.
Following is sample output of the show environment last command:
Router# show environment last
chassis corepreviously measured at 34C/93F
chassis inletpreviously measured at 28C/82F
chassis outlet 1previously measured at 31C/87F
chassis outlet 2previously measured at 33C/91F
+2.5 Vpreviously measured at +2.59
+3.3 Vpreviously measured at +3.32

+12.3 Vpreviously measured at +12.99
+12.3 Vpreviously measured at +12.33
-12.5 Vpreviously measured at -12.43
The show environment table command displays the temperature and voltage thresholds for each
temperature sensor and for each monitored status level, which are related to those thresholds listed in
Table 1-17
Following is sample output of the show environment table command:
