Installation --continued

Installing the twisted-pair copper cable

1.Locate or build an IEEE 802.3 compliant 10Base-T or 100Base-TX cables, with male RJ-45 connectors installed onto both ends.

2.Connect the RJ-45 connector at one end of the cable to the RJ-45 port on the bridging media converter as shown below.

3.Connect the RJ-45 connector at the other end of the cable to the RJ-45 port on the other device (switch, workstation, etc.) as shown below.

Note: The MDI (straight-through)cable or the MDI-X (crossover) cable connection is configured automatically, according to network conditions.

Transceiver	Switch,Workstation, etc.

Connecting power to the bridging media converter

AC/DC:

1.Connect the barrel connector of the adapter to the power port of the bridging media converter (located on the back of the converter shown below).

2.Connect the power adapter plug into AC power: if all the configuration switches are in the UP position, the port LEDs will flicker during the initialization process and then go OFF.

Note: The power-on LED will be lit (ON).

Operation

Status LEDs

There are three (3) LEDs on the converter chassis front panel and two (2) on each TP port.

Chassis LEDs

Power (PWR):	LED ON indicates connection to an external AC power source
Primary:	ON when the primary port is in use
Backup:	ON when the backup port is in use
TP port LEDs
LINK/ACT/SPD:	Green (ON) for 100 Mbps and Link/Act; Flashing when
	transmitting data; Orange for 10Mbps
Duplex (DPX):	Green (ON) for full duplex; OFF for half duplex
TP Port

Linx/Act/SPDDup

Cable Specifications

Copper cable (10Base-T/100Base-TX)

Ensure that the correct cable type is installed to support the highest speed and mode of operation. Though category 3 cable is adequate for a 10Base-T installation, category 5 cable is recommended, since category 3 cable DOES NOT support 100Base-TX.

Category 3:	(minimum requirement for 10 Mbps operation)
Gauge:		24 to 22 AWG
Attenuation:		11.5 dB/100m @ 5-10 MHz
Maximum cable distance:		100 meters
Category 5:	(minimum requirement for 100 Mbps operation)
Gauge:		24 to 22 AWG
Attenuation:		22.0 dB/100m @ 100 MHz
Maximum cable distance:		100 meters

•Straight-through (MDI) or crossover (MDI-X) cable may be used.

•Shielded (STP) or unshielded (UTP) twisted-pair cable may be used.

•Pins 1/2 and 3/6 are the two active pairs in an Ethernet network.

•Use only dedicated wire pairs for the active pins:

(e.g., blue/white & white/blue, orange/white & white/orange, etc.)

•Do not use flat or silver satin wire.
