GBIC Transceivers

The Gigabit Interface Converter (GBIC) ports on your
system connect to Gigabit Ethernet networks through
a GBIC transceiver (Figure 1), providing a high-speed
connection over fiber-optic cable. The transceiver
connects to the network using a fiber-optic duplex
subscriber connector (SC). You can remove and
replace the transceiver with the system powered on,
which is called hot-swapping.
