Table 4 Stacking LED Indications

LED	LED	Description
Description	Indication
	All LEDs off	The device is operating as a standalone
		switch.
S1	Green	The device is in stacking mode, and is
		either the master or backup of the stack,
		which is determined by the master
		election algorithm.
S2	Green	The device is master-enabled, and is
		either the master or backup of the stack,
		which is determined by the master
		election algorithm.
S3	Green	The device is operating as Stack Member

Mode LEDs You can select a particular status mode for a RJ-45 Port on either the AT- 8000GS/24 Gigabit Ethernet Switch or the AT-8000GS/48 Gigabit Ethernet Switch by using the Mode Select switch button on the front panel. (The AT-8000GS/24POE Gigabit Ethernet Switch does not have a Mode select switch.)

The MODE LEDs indicate which mode is actively displayed on each corresponding RJ-45 port Mode LED. For example, if the mode selected is "COL", then the LED on each port indicates the collision status of that port. See “RJ-45 Port LEDs on AT-8000GS/24 & AT-8000GS/48” on page 19 for the location of the RJ-45 MODE LED on each port.
