Cisco Systems UBR7100E manual Router# show environment last

Chapter 6 Maintenance

Environmental Monitoring and Reporting Functions

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		core	previously measured at 34C/93F
chassis		inlet	previously measured at 28C/82F
chassis		outlet 1	previously measured at 31C/87F
chassis outlet 2			previously measured at 33C/91F
+2.5 V			previously measured at +2.59
+3.3 V			previously measured at +3.32
+5.15	V		previously measured at +5.13
+12.3	V		previously measured at +12.99
+12.3	V		previously measured at +12.33
-12.5	V		previously 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 6-1and Table 6-2.

Following is sample output of the show environment table command:

Router#		show environment table
Sample Point			LowCritical	LowWarning	HighWarning	HighCritical
chassis		core			49C/120F	54C/129F
chassis		inlet			43C/109F	48C/118F
chassis		outlet 1			46C/114F	51C/123F
chassis		outlet 2			47C/116F	52C/125F
+2.5 V			+2.35	+2.39	+2.69	+2.72
+3.3 V			+3.11	+3.19	+3.39	+3.47
+5.15	V		+4.88	+5.00	+5.23	+5.39
+12.3	V		+11.53	+11.77	+12.76	+13.05
+12.3	V		+11.53	+11.77	+12.76	+13.05
-12.5	V		-10.20	-11.24	-13.71	-14.33

Note Temperature ranges and values are subject to change.

The show environment all command displays an extended report that includes temperature readings and voltage readings.

Following is sample output of the show environment all command:
