•Be certain that 10BASE-T/100BASE-TX MDI/MDI-X switch is set correctly for site installation. .

•Set Switches according to site installation:

Switches 1-5: The transceiver is shipped with rocker switch 1 set to the default ON=UP and with switches 2-5 set to the default OFF=DOWN, setting the transceiver physical address to a value of “1”.

NOTE: Straight-through/crossover requirements are satisfied using the MDI/MDI-X switch with straight-through cable. Cable connections between a hub and the media converter require the MDI/MDI-X switch to be set to MDI. Cable connections between the media converter and a terminal, transceiver or NIC require the switch to be set to MDI-X

		and referring to label at front of media converter,

Troubleshooting the Transceiver

If the E-TX-MC01 transceiver fails, determine the answers to the following questions:

1.Is the power LED on the transceiver illuminated?

NO

•Verify that the transceiver is installed properly in the MII port and that the device is powered ON?

•Contact Technical Support at (800) 260-1312 or at (800) LAN-WANS.

YES

•Proceed to step 2.

2.Is the Link LED illuminated?

NO

•Check the copper cables for proper connection. (If possible, try a different cable.)

•Try setting a non-zero physical address.

•Contact Technical Support at (800) 260-1312 or at (800) LAN-WANS.

YES

•Proceed to step 3.

3.Is the copper cable connected properly?

NO

•Verify that straight-through copper cable is installed and that MDI-MDI-X switch is set correctly.

•Contact Technical Support at (800) 260-1312 or at (800) LAN-WANS.

YES

physical address to a site-specific value from 1 to 31.

Switch 6-7: The transceiver is shipped with rocker switches 6 and 7 set to the default OFF=DOWN, which sets the data-transfer mode to “auto- negotiation”..

•Set switch 6 to ON=UP when the transceiver is connected to a 100BASE-TX half-duplex device.

•Set switch 7 to ON=UP when the transceiver is connected to a 10BASE-T half-duplex device.

CABLE SPECIFICATIONS

The physical characteristics of the media cable must meet or exceed IEEE 802.3u 100BASE-TX specifications.

100BASE-TX CABLE SPECIFICATIONS

Category 5 wire or better is required. Either shielded twisted pair (STP) or unshielded twisted pair (UTP) can be used. Use a straight- through cable configuration (see back page).

Category 5:
Gauge	24 to 22 AWG
Attenuation	20 dB/1000’ @ 10 MHz
Impedance	100 Ω ±10% @ 10 MHz
Maximum Cable Distance:	100 meters (330 feet)Maximum
