Environmental Monitoring and Reporting Functions

Table 6-1 Typical Processor-Monitored Temperature Thresholds

Parameter	High Warning	High Critical
Core	120°F (49°C)	129°F (54°C)
Chassis inlet	109°F (43°C)	118°F (48°C)
Chassis outlet 1	114°F (46°C)	123°F (51°C)
Chassis outlet 2	116°F (47°C)	125°F (52°C)

Note If the system reports temperatures in the critical range, you must manually shut down the router. The processor does not shut down the router automatically.

Parameter	Low Critical	Low Warning	High Warning	High Critical
+2.5 V	+2.35 V	+2.39 V	+2.69 V	+2.72 V
+3.3 V	+3.11 V	+3.19 V	+3.39 V	+3.47 V
+5.15 V	+4.88 V	+5.00 V	+5.23 V	+5.39 V
+12.3 V	+11.53 V	+11.77 V	+12.76 V	+13.05 V
+12.3 V	+11.53 V	+11.77 V	+12.76 V	+13.05 V
–12.5 V	–10.20 V	–11.24 V	–13.71 V	–14.33 V

Displaying Environmental Status Reports

Cisco uBR7100 series routers display warning messages on the console if chassis interface-monitored parameters exceed a desired 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.

Caution To prevent overheating the chassis, ensure that your system is drawing cool inlet air. Overtemperature 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 other device.

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
