With 24 parallel bridging ports (i.e., 24 distinct collision domains), this

switch can collapse a complex network down into a single efficient bridged

node, increasing overall bandwidth and throughput.

In the figure below, the 1000BASE-T RJ-45 ports on the switch are

providing 1 Gbps full-duplex connections for up to 24 local segments. In

addition, the switch is also connecting remote servers over fiber optic

cable at 1 Gbps.
