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.

 

Xmt

Transmit. Lights when the switch is transmitting

 

 

packets from this port to another port. Normally

 

 

blinks at regular intervals, even if no devices are

 

 

connected, while it updates the internal SNMP

 

 

agent.

 

Rcv

Receive. Lights when packets are received on this

 

 

port, even if they are not forwarded.

received on their own wire pair, so they can’t

 

 

collide.
