Stacking Guidelines - Allied Telesis x530DP Series Installation Manual

Stacking Guidelines

This section lists the general guidelines to building a VCStack of x530DP
Series switches. Stacking guidelines differ depending on the version of the
AlliedWare Plus management software on the switches. (Instructions in
Chapter 9, "Building the Trunk with Default 10 Gbps Stacking Ports" on
page 129 and Chapter 9, "Building the Stack Trunk with 5Gbps Multi-
Speed Ports" on page 127 explain how to display the version numbers of
the management software.)
A stack can have up to eight x530DP Series switches.

A stack can have x530DP, x530, and/or x530L Series switches.

However, this type of stack, referred to as a mixed stack, requires
a license and additional configuration commands. Refer to "Mixed
Switch Stacks" on page 68.
Stacking is enabled by default on x530DP Series switches.

The switches of a stack must be connected with a stack trunk,

consisting of a minimum of two ports per switch.
The default stacking ports are:

– x530DP-28GHXm: 27 and 28
– x530DP-52GHXm: 51 and 52
You can increase the bandwidth and resiliency of the stack trunk

by also using these ports as stacking ports:
– x530DP-28GHXm: 25 and 26
– x530DP-52GHXm: 49 and 50
Stack trunks can also be built with the four multi-speed 5Gbps

ports.
Although the default ports support 1Gbps and 10Gbps

transceivers, stack trunks require 10Gbps transceivers. Stack
trunks are not supported with 1Gbps transceivers.
A stack of x530DP Series switches cannot contain other stacking

switches, such as x600 or x610 Series switches.
The links of a stack trunk must be direct connections between

switches. You cannot install networking devices, such as media
converters or Ethernet switches, 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.
When using multi-speed ports as a stack port, it supports 1 to 8

links.
