10/100/1000Base-T Twisted Pair Port
The 10/100/1000Base-T twisted pair port is described below:
Type of
Connector
The twisted pair port has an 8-pin RJ-45 connector. The port uses four
pins when operating at 10 or 100 Mbps and all eight pins when operating
at 1000 Mbps. For the port pinout details, refer to “10/100/1000Base-T
Port Pinouts” on page 60.
Port Speed
The twisted pair port can operate at 10, 100, or 1000 Mbps. IEEE 802.3u-
compliant, the unit can set the speed of the port automatically with Auto-
Negotiation or you can set the speed manually with the DIP switches on
the back panel.
Note
The twisted pair port has to be set to Auto-Negotiation to operate at
1000 Mbps.
Duplex Mode
The port can operate in either half- or full-duplex mode. If Auto-Negotiation
is activated on the port, the duplex mode is set automatically. If Auto-
Negotiation is disabled, you set the duplex mode manually using the DIP
switches.
Note
In order for the media converter to successfully Auto-Negotiate the
duplex mode of the twisted pair port with an end-node, the link
partner should also be using Auto-Negotiation. Otherwise, a duplex
mode mismatch can occur. While configured for Auto-Negotiation,
port will default to half-duplex if it detects that its link partner is not
using Auto-Negotiation. This will result in a mismatch if the end-node
is operating at a fixed duplex mode of full-duplex.
Maximum
Distance
The 10/100/1000Base-T twisted pair port has a maximum operating
distance of 100 meters (328 feet).
