554 ! Monitoring Redundant SCG Status
Alternative Action If there is a problem with the SCG status, you can display more detailed SCG
environmental information with the following CLI command:
user@host> show chassis environment scg
The command output is as follows:
t320@host>
show chassis environment scg
SCG 0 status:
State Online - Master clock
Temperature 30 degrees C / 86 degrees F
Power:
GROUND 0 mV
3.3 V 3317 mV
5.0 V 5072 mV
5.6 V 5697 mV
1.8 V bias 1794 mV
3.3 V bias 3304 mV
5.0 V bias 4991 mV
8.0 V bias 7318 mV
BUS Revision 40
SCG 1 status:
State Online - Standby
Temperature 29 degrees C / 84 degrees F
Power:
GROUND 0 mV
3.3 V 3318 mV
5.0 V 5084 mV
5.6 V 5704 mV
1.8 V bias 1782 mV
3.3 V bias 3286 mV
5.0 V bias 5003 mV
8.0 V bias 7323 mV
BUS Revision 40
The command output displays the status for each SCG slot 0 and 1. The operating
status can be
Present, Online, Offline, or Empty. If Online, it can be the clock source
(
Master clock) or backup (Standby). As shown in the output, the redundant SCG is
SCG1, with a status of Standby. The command output displays the temperature of
the air flowing past the SCG. The command output also displays information about
the SCG power supplies and the SCG circuitry revision level.
