2.5 Connecting the LSW Switch

Use the following procedures to connect 10BASE-T or 100BASE-TX net-
work devices to the LSW switch:

The following table describes the two cable types:

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

Duplex mode: each 10/100 port (Ports 1 and 2) can detect duplex mode
automatically Ð the device being connected to must support 802.3u
autonegotiation for full duplex to be used; duplex mode for 10Mbps
ports can be selected via switches on the back of the unit.
