SFP Transceiver Slots
The AT-9424Ts and AT-9424Ts/XP Switches feature four slots for optional
Gigabit Ethernet SFP transceivers. You can use the transceivers to
connect the switches to network devices over large distances using fiber
optic cable. Figure 4 illustrates an SFP transceiver.
Each SFP slot is paired with a twisted pair port. A link on an SFP
transceiver takes priority in the event both an SFP transceiver and its
paired twisted pair port have established links to their respective end
nodes. For further information, refer to “Redundant Twisted Pair Ports” on
page 23.
