9.1. Maintenance for System Control Board

9.1.1. Check

1) Checking running status of the system control board through the indicator

The corresponding status indicator in the front panel of the system control board is used to display the running status of the device, and it plays an important role in the fault analysis and location.

The rough position or cause of the fault can be found through the indicator status, and the indicator status is helpful for the next processing procedure. The indicator does not have the sufficient information, so it is usually used with the coordination of the alarm information analysis.

Check the system running status according to indicator description in the Table 9–1. When finding some exceptional cases, you should take some measures in time.

					The maintenance personnel should pay more attention to the
					study of the indicator meaning, and have the rapid response
		prompt			capability when some faults occur to the system.

Table 9-1 Description of LED status of the system control board SMUB

		Indicator			Flag	Color	Status	Description
		System			RUN	Green	Off	The system does not run.
		status					Flashing	The system runs normally.
		indicator			ALM	Red	Off	The system runs normally.
							ON	The system has an alarm. When the
								device starts the self-inspection, this
								indicator will flash once, but it does not
								indicate an alarm.
		Status			LINK	Green	Constantly	When a stable link is built in the port, the
		indicator					on	corresponding indicator is constantly on.
		of	the				Off	No link is in the port.
		Ethernet			ACT	Green	Flashing	Data is being received/transmitted in the
		interface						port
							Off	Data is not received/transmitted in the
								port

Note: The flashing frequency of the system indicator in the master system control board is faster than that in the standby

system control board. The system indicator of the master

prompt system control board flashes three times per second, and the system indicator of the standby system control board flashes once per second.
