The Physical Stack

x610 Series Layer 3 Gigabit Ethernet Switches Installation Guide

Depending on the switch types used, a stack can comprise from 2 to 8 individual stack members interconnected via high speed stacking links. A stack always has a primary stack member called the stack master, and can contain up to 7 other stack members. For information about VCStack stacking modules available and cable specifications, see “Connecting switches into a stack” on page 67 for more information.

Two Switch Stack Configuration

This configuration, shown in Figure 33, uses two switches that are connected back to back via two high-speed stacking links. In this configuration the stack can still function using only a single high speed link. Note that stacking ports labeled 1 must connect to stacking ports labeled 2. Also, in this example the switches have AT-StackXG stacking modules installed.
