Use the following procedures to connect 100BASE-TX network devices to the hub:

LFH4-M	Ports 1-4	Uplink Port

PC, Workstation	S	C
Server	S	C
Hub, Switch port	C	S
Hub, Switch uplink port	S	C

S = Straight Cable C = Crossover cable

NOTE: If the Uplink Port is being utilized on the LFH hub, the adja- cent Port may not be used. Conversely, if that Port is being utilized, the Uplink Port may not be connected.

The following table describes the two cable types:

	Straight cable	Crossover cable
Pin 1	TD+	RD+
Pin 2	TD-	RD-
Pin 3	RD+	TD+
Pin 6	RD-	TD-

Make sure that the length of the straight-through cable between the LFH hub and the other device does not exceed 100 meters, including all patch cables and cross-connect wires.

Make sure that the length of the straight-through cable between two hubs does not exceed 5 meters.
