Chapter 1 Product Overview Functional Overview The low warning and high warning ranges in Table 1-11 are informational and if a low warning or high warning message appears, the warning message does not signify that an error or hazard is occurring. A high warning message sometimes appears in a lightly loaded chassis, especially if the router is running without port adapters or with dual power supplies. Adding current load to the router may remove the warning; this can easily be achieved by installing one or more port adapters. Below are sample high warning messages from chassis with 3V and 5V power supplies: Router(boot)# 00:00:44:%ENVM-4-ENVWARN:+3.45 V measured at +3.57 Router(boot)# 00:04:49:%ENVM-4-ENVWARN:+5.15 V measured at +5.33 Note Low critical or high critical warning messages should be addressed immediately through the normal field support procedures. Below are sample high critical messages from chassis with 3V and 5V power supplies: Router(boot)# 00:02:47:%ENVM-2-ENVCRIT:+3.45 V measured at +3.66 Router(boot)# 00:06:51:%ENVM-2-ENVCRIT:+5.15 V measured at +5.47 Reporting Functions The Cisco 7206 displays warning messages on the console if chassis interface-monitored parameters exceed a defined 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 another device. The show environment command display reports 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: +3.45 V measured at +3.83 V OL-5102-02 Cisco 7206 Installation and Configuration Guide 1-33
