Trunks of Copper 10/100/1000Mbps Ports
You can use the copper Gigabit ports on the front panels as the trunks for
stacks of x930 Switches. Here are the guidelines:

Stacks can have up to four switches.

Stacks can have both 28-port and 52-port x930 Switches.

Trunks can have up to eight copper Gigabit ports per switch.

For 52-port switches, use only ports in the range 1 to 24 for the
trunk ports.

You should try to use the same Gigabit ports as the trunk on all the
switches in the stack. This can make managing and
troubleshooting stacks easier.

You have to configure the master and member switches of the
stack by designating the Gigabit ports of the trunk with the STACK
ENABLE FRONT-PANEL-PORTS and STACKPORT commands,
and adding the members switches to the master switch as
provisioned switches.

The Gigabit ports of the trunk have to be at their default settings.
You cannot change the settings of trunk ports.
Note
Trunks of copper Gigabit ports require AlliedWare Plus version
5.5.1-2.1 or later.
For instructions, refer to Chapter 13, “Building the Stack with Copper or
SFP Gigabit Ports” on page 165
Here are examples of stacks with trunks of copper Gigabit ports. Figure 24
is of a stack of two switches. The trunk uses ports 1 to 4 on both switches.
(The maximum is eight ports per switch.) This is not a requirement, but
managing the stack will be easier if you select the same ports as the trunk
on all the switches and connect the same ports together, when possible.
