 Auto-MDI/MDIX
 100 meters (328 feet) maximum operating distance
 IEEE 802.3x Flow Control in 10/100Base-TX full-duplex operation
 IEEE 802.3x Back Pressure in 10/100Base-TX half-duplex
operation
 IEEE803.3z 1000Base-T Flow Control
 RJ-45 connectors
SFP Slots All three switches support both 100Base-FX and 1000Base-SX/LX
transceivers. The switches support slots for SFPs as follows:
 One SFP slot on the AT-GS908M switch
 Two SFP slots on the AT-GS916M switch
 Four SFP slots on the AT-GS924M switch
Note
The AT-GS916M and AT-GS924M SFP slots are paired with
twisted-pair ports on the switch to form combo ports. For more
information, see “Combo Ports” on page 22.
Note
You must purchase SFP transceivers separately. For a list of
supported transceivers, contact your Allied Telesis distributor or
reseller.
