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.
