Chapter 1 Cisco 7200 VXR Product Overview
Functional Overview
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.
Note The low warning and high warning messages are no longer in existence beginning with
Cisco IOS Release 12.0(23) and Cisco IOS Release 12.3(8).
