D-Link DES-802 - Switch User Manual - Port 1: 3-In-1 Combo

Overview
Port 1: 3-in-1 Combo
Port 1 has three different connectors – UTP/STP, BNC, and AUI.
The twisted-pair connector (UTP/STP) of Port 1 is a 10/100Mbps, N-Way
RJ-45 port for use with unshielded or shielded twisted-pair cabling. Because
it is an N-Way port, the operating mode of connected stations (10Mbps
Ethernet or 100Mbps Fast Ethernet) is automatically detected and the port is
auto-configured to match. Please use crossover cabling unless you are
connecting to a straight-through uplink port on a switch or hub. The
twisted-pair connector operates at an user-selectable effective speed of 10 or
100Mbps for half-duplex mode and 20 or 200Mbps for full-duplex mode. In
either mode, the twisted-pair connector can operate up to 100 meters of
Category 3, 4, or 5 UTP/STP cable.
The BNC connector is a standard connector for use with thin Ethernet coaxial
cabling (half-duplex mode only).
The AUI connector is for attaching the switch to an external transceiver for a
thick Ethernet or Fiber-optic connection (half-duplex mode only).
Important Note: The Port 1 connectors are arranged in a
“priority” scheme. That is, one connector has a higher
priority than the other two, so if a device is connected
to that connector, the other connectors are disabled.
The priority is: UTP/STP – highest priority; AUI –
second priority; BNC – lowest priority. Only one
connector at a time may be used.
