Stacking Guidelines - Allied Telesis x530 Series Installation Manual

Stacking Guidelines

This section lists the general guidelines to building a VCStack of x530
switches.
A stack can have up to four x530 Series switches.

Stacking is enabled by default on x530 Series switches.

The switches of a stack have to be connected with a stack trunk,

consisting of a minimum of two ports per switch.
Ports 27 and 28 are the default stacking ports.

You can increase the bandwidth and resiliency of the stack trunk

by also using ports 25 and 26 as stacking ports.
Although ports 25 to 28 support both 1 Gbps and 10 Gbps

transceivers, stack trunks require 10 Gbps transceivers. Stack
trunks are not supported with 1 Gbps transceivers.
No additional software or licenses are required for stacking.

The switches of a stack can be the same or different x530 Series

models.
A stack of x530 Series switches cannot contain other stacking

switches, such as x600 or x610 Series switches.
The switches of a stack must be connected with a stack trunk

consisting of a minimum of two ports on each device.
The links of a stack trunk must be direct connections between

switches. You cannot install a networking device, such as a media
converter or Ethernet switch, between two stacking ports.
SFP+ transceivers and direct attach cables used for a stack trunk

must be from Allied Telesis. Switches will not form a stack with
transceivers from other network equipment providers. For a list of
supported transceivers, refer to the product data sheet on the
Allied Telesis web site.
