10 Gbps Stack Trunks

44
You can build stack trunks with 10 Gbps SFP+ transceiver slots on the
switches. The guidelines are described here:
Stacks can have two, three, or four switches.

For stacking ports, you can use ports 25 to 28 at 10 Gbps.

Ports 1 to 24 cannot be used in a stack trunk.

SFP+ transceivers must be from Allied Telesis and be approved

for use in the product. For a list of supported 10 Gbps SFP+
transceivers, refer to the product data sheet on the Allied Telesis
web site.
Note
Transceivers are purchased separately.
The 10 Gbps stacking ports and transceiver slots can be used as

regular networking ports by disabling the stacking feature.
A stack trunk can be either linear or ring. Ring is recommended

because it adds redundancy. The stack can continue to function
even if a trunk link fails. See Figure 9 on page 45.
A stack trunk can have either fiber optic or AT-SP10TW direct

connect cables, do not use both types in the same stack.
