10/100 ETHERNET SWITCHES
2. Introduction
2.1 Description
The 10/100 Ethernet Switch provides extra Fast
Ethernet ports to segment network traffic,
extend Fast Ethernet connection distance, and
convert data packets between different
transmission speeds. All of the UTP ports on
the switch support MDI/MDI-X, so you can
connect either a straight-through or crossover
cable to another switch or hub.
Three models are available. The LB8505A has 5
shielded, auto-negotiating 10BASE-T/100BASE-
TX RJ-45 ports. The LB8508A has 8 RJ-45 ports,
and the LB8516A has 16. All of the switch’s
UTP ports support full and half-duplex modes.
When running in half-duplex mode, ports
configured as 10BASE-T provide 10 Mbps of
bandwidth; ports configured as 100BASE-TX
give you 100 Mbps of bandwidth. In full duplex
mode, this bandwidth doubles. Ports
configured as 10BASE-T give you 20 Mbps of
bandwidth; ports configured as 100BASE-TX
provide 200 Mbps of bandwidth. The switch is
