The switches have two slots for 100Mbps 100Base-FX or 1000Mbps
1000Base-SX/LX fiber optic transceivers. The transceivers can be used to
connect the switches to other network devices over large distances, build
a high-speed backbone network between network devices, or connect
high-speed devices, such as servers, to your network.
The switches support a variety of short and long distance, 100 and 1000
Mbps fiber optic SFP modules. For a list of supported SFP modules,
contact your Allied Telesis representative or visit our web site.
The two SFP slots are paired with the two 10/100/1000Base-T ports. The
combo ports are listed in Table 9.

AT-FS970M/48 and
AT-FS970M/48PS
The rules for using the combo ports are listed here:
Only one port in a combo pair is active at a time.
The twisted pair port is the default active port.
The SFP slot becomes active when an SFP transceiver establishes
a link to another network node.
The twisted pair port of a combo pair remains deactivated so long
as the SFP transceiver has a link to another network device.
The switch automatically reactivates the twisted pair port if the
companion SFP module loses its network link.
The twisted pair port and SFP module of a combo port share the
same settings, such as VLAN assignments, access control lists,
and spanning tree.
