A. Using straight cable

When using straight cable, this is done from the uplink (MDI-II) port

of the DSS-8+ (DSS-8+ A) to any of the 10Mbps or 100Mbps (MDI-

X) port of the other switch (switch B) or other devices.

B. Using crossover cable

When using crossover cable, this is done from any (MDI-X) port of

the DSS-8+ (DSS-8+ A) to any of the 10Mbps, 100Mbps (MDI-X)

port of the other switch (switch B) or other devices.

1. The “100LINK/ACT,10LINK/ACT” LED indicator light

green for hookup to 100Mbps speed or light amber for

hookup to 10Mbps speed.

2. The “Full-Duplex/Collision” LED indicator depends upon LAN

card capabilities for full-duplex or half-duplex

Port Speed & Duplex Mode

After plugging the selected cable to a specific port, the system uses

auto-negotiation to determine the transmission mode for any new

twisted-pair connection:

If the attached device does not support auto-negotiation or has

auto-negotiation disabled, an auto-sensing process is initiated to

select the speed and set the duplex mode to half-duplex.
