Monitor the Redundant SCG Environmental Status
Purpose
To isolate problems in the redundant SCG by checking the environmental status.
Action
To check the redundant SCG environment status, use the following command:
Sample Output
t320@host> show chassis environment
Class Item Status Measurement
Power PEM 0 Absent
PEM 1 OK
Temp SCG 0 OK 30 degrees C / 86 degrees F
SCG 1 OK 29 degrees C / 84 degrees F
[...Output truncated...]
Meaning
The command output displays the status and temperature for each SCG.
If there is a problem with the SCG status, you can display more detailed SCG environmental information with the following command:
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.
