1 Intel Express 100BASE-TX Switching Hub

NOTE

The default configuration of all ports is half-duplex mode.

To change to full duplex, use the Console Manager. See page 19 for instructions.

Using the Switch

The switch requires minimal user intervention. It automatically learns the addresses of new stations as they appear, and will relearn addresses dynamically if the network is reconfigured.

Each of the Fast Ethernet ports has six status LEDs. There is a separate bank of four LEDs for the management status.

Ports on the switch are wired MDI for connection to MDI-X ports using a straight-through UTP cable. See page 9 for more information.

Port status LEDs

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

Port 3

Xmt FC/FD Mgmt

Rcv Clsn Link

MDI

Xmt Transmit. Lights when the switch is transmitting packets on this port.

Rcv Receive. Lights when packets are received on this port, even if they are not forwarded.

FC/FD Flow Control (default) or Full Duplex. Blinks on when flow control is activated. If flow control is disabled, the LED blinks on when a packet is lost. If full duplex is enabled on the port, the LED is normally on continuously, and blinks off when a packet is resent. Flow control is not possible, nor needed, when full duplex is enabled.

Clsn Collision. Lights whenever a collision occurs while the port is transmitting. Collisions are normal in an Ethernet environment. However, if the collision LED is on continuously, you may have a problem with a device on the segment.
