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

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 2-6and 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
