High Speed Stacking Cables (1.0 meter) - StackXG/1

The specifications for SFP+ transceivers able to be installed in the

AT-x6EM/XS2 stacking module can be found on our Allied Telesis web

site at www.alliedtelesis.com.

VCStack restrictions

There are some restrictions to what products and connections you can

combine in a single stack. In general, different switch families cannot be

stacked together and you cannot combine different stacking methods or

cables.
x610 Series switches can stack with other x610 switches and with x600

switches, as described in ”Mixed-mode VCStack (stacking x610 switches

with x600 switches)” below.
The maximum stack size is:

ˆ

8, when stacking x610 Series switches

ˆ

4, when stacking 600 Series with x610 Series switches

ˆ

4, when stacking x600 Series switches

Mixed-mode VCStack (stacking x610 switches with x600 switches)

The x600 and x610 switches support a feature called mixed-mode

stacking. This feature allows x600 and x610 units to be stacked together

to form a single stack. Note that if a x610 switch is to be part of

mixed-mode VCStack then an AT-StackXG must be installed in the switch.
In a mixed-mode VCStack, for stack compatibility the x610 Series

switches operate as x600 Series switches, not as x610 Series switches. If

you stack x610 Series switches with x600 Series switches, note the

following restrictions:

ˆ

Synchronization disabled. When mixed-mode stacking is enabled the

VCStack software auto synchronization feature is disabled because

the x600 and x610 run different software releases. When mixed-mode

stacking is disabled then the software synchronization feature is

re-enabled. For more information about VCStack software auto

synchronization refer to the Stacking Introduction and Stacking
Commands

chapters in the AlliedWare Plus

Operating System

Software Reference

from www.alliedtelesis.com.

ˆ

Software upgrades. Because software releases are not synchronized

in a mixed-mode stack, the preferred release file must be manually

copied to each stack member and set individually. The simplest way to

do this is to 'remote-login' to each stack member and then enter the

‘boot system’ command.
