Chapter 1 Cisco 7200 VXR Product Overview Functional Overview Table 1-37 Parameter +3.45V +5.15V +12.15V -11.95V Typical Power Supply-Monitored DC-Voltage Thresholds Low Critical +3.26V +4.86V +11.39V -9.52V Low Warning +3.34V +4.99V +11.67 -10.73 High Warning +3.55V +5.31V +12.62V -13.16V High Critical +3.63V +5.43V +12.91V -14.38V Note A low warning or high warning message does not mean that the router is at risk of malfunctioning or being damaged. The low warning and high warning ranges in Table 1-34 and Table 1-35 are informational. 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 be achieved easily 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.
