LED	State	Description
L/A 2	Off	Stack Port 2 has not established a link to a
		stacking port on another VCStack stacking
		module.
	Solid	Stack Port 2 has established a link to a
	Green	stacking port on another VCStack stacking
		module.
	Flashing	Stack Port 2 has established a link to a
	Green	stacking port on another VCStack stacking
		module and is sending or receiving packet
		traffic.
PRES	Off	The expansion slot for the VCStack stacking
		module is empty.
	Solid	A VCStack stacking module is installed in the
	Green	switch.
MASTER	Off	Indicates that the switch is not the Stack
		Master.
	Flashing	Indicates the specific stack member’s ID of the
	Green	switch in response to the ‘show stack indicator’
		command. The LED will repeatedly flash ‘n’
		times in quick succession, followed by a longer
		pause, where n is the stack member's ID.
	Solid	Indicates that the switch is the STACK Master.
	Green

The proprietary high-speed communication protocol that is used over the stacking links requires multiple twisted pairs and a high level of shielding. This means that to stack x610 switches, specialized cables and connections are required.

VCStack Stacking Modules, Cables, and Connections

The stacks are connected via the stacking ports on the VCStack stacking modules, which are installed in the back of each switch. There are two VCStack stacking modules available:

The AT-StackXG, which has two full-duplex, 12 Gbps stacking ports

The AT-x6EM/XS2, which has two 10 Gbps SFP+ stacking slots

The following cables are used to connect the stacking ports when using
