8691omSF module LEDs

The Switch LEDs and the CPU LEDs serve as a bar graph to indicate card activity. The Switch bar graph increases as the switch fabric utilization increases. The CPU bar graph increases when the CPU is actively performing tasks, such as learning media access control (MAC) addresses, updating routing tables, or interacting with the device management station.

"8691omSF module LEDs" (page 65) describes the 8691omSF module LEDs.

Label	Color/State	Meaning
Mz	N/A	Reserved for future use.
Link	Green/Steady	The management port is connected, and the
		link is good.
	Off	There is no link to the management port.
100	Green/Steady	The management port is operating at 100 Mb/s.
	Off	The management port is operating at 10 Mb/s.
Switch	Green	The number of lit LEDs indicates the utilization
Utilization		level of the switch fabric as follows:
(8 LEDs)		1	LED = 10 Mb/s	5 LEDs = 10 Gb/s
		2 LEDs = 100 Mb/s		6 LEDs = 20 Gb/s
		3	LEDs = 1 Gb/s	7 LEDs = 40 Gb/s
		4	LEDs = 5 Gb/s	8 LEDs = 64 Gb/s
