Using the Switch, Port status LEDs, Xmt, Rcv | Intel 10/100 guide

C H A P T E R 1 Hardware Installation and Network Topology

Ports on the switch are wired MDI-X for connection to MDI ports using a straight-through UTP cable. See page 8 for more information.

Using the Switch

The switch requires minimal user intervention. It automatically learns the addresses of new devices as you connect them, and will relearn addresses dynamically if you reconfigure the network. It also automatically detects the speed of connected devices. You don’t need to manually set the speed.

Port status LEDs

Port LEDs provide information about each port’s configuration and the status of devices connected to the ports.
