Designating Sfp+ Ports S1 And S2 As The Stack Trunk - Allied Telesis AlliedWare Plus Installation Manual

Designating SFP+ Ports S1 and S2 as the Stack Trunk

This procedure designates the SFP+ ports S1 and S2 ports as the trunk
ports on switches containing AT-StackQS Cards. Review the following
information before performing the command:
The SFP+ ports S1 and S2 are the default trunk ports in switches

that are at the default settings and do not contain AT-StackQS
Cards. If none of the switches for the stack contains the card, you
can skip this procedure and go to "Powering On the Switches
Sequentially" on page 152 or "Powering On the Switches
Simultaneously" on page 154.
For switches containing AT-StackQS Cards, the default trunk ports

are the two 40Gbps ports on the cards. To use the front panel
SFP+ ports S1 and S2 as the stack trunk instead, you have
perform the STACK ENABLE BUILTIN-PORTS command, as
explained in the following procedure. The command designates the
SFP+ ports S1 and S2 as the trunk ports and redefines the 40Gbps
ports on the cards as regular networking ports.
You must also perform this command if you designated front panel

Gigabit ports as the trunk, but later decide to use the SFP+ ports
S1 and S2 instead.
You should disconnect all cables from the SFP+ ports S1 and S2

and AT-StackQS Cards before performing the procedure.
This procedure assumes the following:
You performed the procedures in Chapter 10, "Displaying the

AlliedWare Plus Version Number" on page 141.
There are no cables connected to the SFP+ ports S1 and S2.

For switches with DC AT-PWR250-80 Power Supplies, you have

already wired the DC connectors. For instructions, refer to Chapter
9, "Wiring the DC Connector on the AT-PWR250-80 Power Supply"
on page 137
After performing this procedure on all switches containing AT-StackQS
Cards, do the following:
1. Power off all the switches that will be in the stack.
2. Cable the SFP+ ports S1 and S2 for the trunk. Refer to "Installing SFP
and SFP+ Transceivers" on page 188 and "Installing AT-SP10TW
Direct Connect Cables" on page 192.
