Cable Requirements

The Lantronix LMS8-A is compatible with UTP

(unshielded twisted pair) and STP (shielded

twisted pair) cables. EIA category 3,4 or 5 cables

can be supported on the RJ45 connectors.

All ports of the LMS8-A are configured as MDI-X

ports; Port 2 has an MDI option for connecting to

hubs, repeaters or other switches.

The following cable configuration is suggested

for the cables attached to an LMS8-A:

LMS8-A End MDI-X MDI

nodes ports ports

Pin 1 TD+ TD+ RD+ TD+

Pin 2 TD- TD- RD- TD-

Pin 3 RD+ RD+ TD+ RD+

Pin 6 RD- RD- TD- RD-

1. The cable between the LMS8-A and an

end-node or another switch is straight

through.

2. The cable between the LMS8-A and a hub

or repeater is not straight through but rather

a “crossover” (transmit pairs and receive

pairs are reversed). By selecting the MDI

option (when available), a straight through

cable can be used.
