1000 Base-SX Gigabit Ports
The IA's Gigabit (1000Base-SX) Ethernet ports are indexed into groups of two ports each.
The ports can operate in full-duplex or half-duplex mode. Each port can be configured as
a switched port or a routed port. The ports have short wave (850 nm) lasers and connect to
multimode-mode fiber (MMF) cables.
Figure 11 shows the front panel of two of the Gigabit ports.
