GBIC Transceiver Slots
The AT-9424T/GB switch has two slots on the front panel labeled 23 and
24 for optional fiber optic Gigabit Interface Converter (GBIC) Ethernet
transceivers. GBIC modules can be installed to interconnect devices over
large distances using fiber optic cable.
Figure 9 illustrates a fiber optic GBIC transceiver.

GBIC Transceiver
GBIC transceiver slots 23 and 24 are paired with twisted pair ports 23R
and 24R. Only one port or transceiver in a pair can be operational at a time
and that a link on a transceiver port takes priority over a link on a twisted
pair port. For further information, refer to “Redundant Twisted Pair Ports”
on page 26.
Note
