x610 Series Layer 3 Gigabit Ethernet Switches Installation Guide

Connecting

switches into a

stack

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
