Monitor the Control Board Status
To check the Control Board status:
Check the Control Board Environmental Status
Purpose
To check the Control Board environmental status for each Control Board installed in the router chassis.
Action
To check the Control Board environmental status, use the following command:
Sample Output
t640@host> show chassis environment cb
CB 0 status:
State Online Master
Temperature 29 degrees C / 84 degrees F
Power:
1.8 V 1805 mV
2.5 V 2501 mV
3.3 V 3293 mV
4.6 V 4725 mV
5.0 V 5032 mV
12.0 V 11975 mV
3.3 V bias 3286 mV
8.0 V bias 7589 mV
GBUS Revision 40
FPGA Revision 7
CB 1 status:
State Online Standby
Temperature 32 degrees C / 89 degrees F
Power:
1.8 V 1802 mV
2.5 V 2482 mV
3.3 V 3289 mV
4.6 V 4720 mV
5.0 V 5001 mV
12.0 V 11946 mV
3.3 V bias 3274 mV
8.0 V bias 7562 mV

FPGA Revision 7
Meaning
The command output lists the Control Board state, redundancy status, temperature, power supply voltages, and circuitry revision level. If you do not specify a Control Board slot number, the command displays the environmental status for each Control Board installed in the router chassis. If you specify a Control Board slot number, the command displays the status for that slot only.
Check the Control Board Status from the Craft Interface
Purpose
To check the Control Board status from the craft interface.
Action
To check the Control Board status from the craft interface, use the following command:
Sample Output
t640@host> show chassis craft-interface FPM Display contents: [...Output truncated...} CB LEDs: CB 0 1 -------------- Amber . . Green * * Blue * . [...Output truncated...]
Meaning
The sample output shows that the routing platform has two Control Boards online and functioning normally. The Control Board installed in slot 0 is functioning as master. If an yellow asterisk displays, the Control Board has failed.
To view the Control Board status, you can do one of the following:
- (T320, T640, T1600, and TX Matrix router) Look at the
router craft interface host module status or look at the LCD display
for any Control Board alarms.
Table 1 describes the T320, T640, and T1600 router host subsystem LED states.
