Cisco 7500 Series Installation and Configuration Guide
OL-5008-03 B0
Chapter 2 Preparing for Installation
Environmental Monitoring and Reporting Overview for the Cisco 7500 Series
If the environmental status is not normal, the system reports the worst-case status level in the last line of
the display.
In the Cisco 7513 and Cisco 7513-MX, the show environment last command retrieves and displays the
NVRAM log showing the reason for the last shutdown (if the shutdown was related to voltage or
temperature) and the environmental status at that time. Air temperature is measured and displayed; the
DC voltages supplied by the power supply are also displayed.
Following is sample output of the show env last command:
Router# show env last

+5 Voltage previously measured at 5.19
-12 Voltage previously measured at -12.17
+24 Voltage previously measured at 23.40
In the Cisco 7513 and Cisco 7513-MX, the show environment table command displays the temperature
and voltage thresholds for each of the three RSP temperature sensors for each monitored status level:
low critical, low warning, high warning, and high critical, which are the same as those listed in Table 2-6
and Table 2-7. The slots in which the RSP can be installed are indicated in parentheses (slot 6 and slot
7). Also listed are the shutdown thresholds for the processor boards and power supplies.
Following is sample output of the sh env table command:
Router# show env table
