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 halfduplex 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 autonegotiation disabled, an auto-sensing process is initiated to select the speed and set the duplex mode to half-duplex. 16
