16
bridges, etc.) via a two-pair Category 5 UTP/STP straight or crossover cable.
Note: Use CAT5 (or better) cable for 100Mbps connection.
A. Using straight cable
When using straight cable, this is done from DSS-16+’s uplink
(MDI-II) port
(Switch A) to any of the 10Mbps or 100Mbps (MDI-X) port of the other
switch (switch B) or other device.
B. Using crossover cable
When using crossover cable, this is done from any
(MDI-X) port of DSS-16+
(Switch A) to any of the 10Mbps, 100Mbps (MDI-X) port of the other
switch (switch B) or other device.
1. The “LINK/ACT” LED indicator lights green indicating 100Mbps
connection or it lights amber indicating 10Mbps speed.
2. The “FDX/COL LED” indicator lights green if the connection is in full-
duplex mode. The LED remains off when the connection is in half-
duplex mode.
Port Speed & Duplex Mode
After a connection is made between DSS-16+ and another Ethernet device,
the system uses auto-negotiation to determine the transmission mode for this
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
.
