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 1-34and Table 1-35are 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.
