SW5 and SW6: Link Modes “Mode 1” and “Mode 2”

These DIP-switches congure the link mode settings. It is recommended to have link modes DOWN

“Off” position (default) during the initial installation. After the circuit has been tested and operational,

congure the module for the desired mode.

Link Segment

In Link Segment mode, all ports operate independently. A loss of a receive link signal will only affect

the port detecting the loss of signal. All the other ports will continue to generate a link signal.

Link Propagate

In Link Propagate mode, the loss of a receive link signal will continue to propagate through to the

next port in the network causing the port to drop link.

Asymmetrical Link Propagate

In Asymmetrical Link Propagate mode, faults are propagated based on the port notation. Port 1 to Port

2 notation indicates the direction the loss of link signal will propagate. A loss of receive link on the ber

optic Port 1 causes the UTP Port 2 to drop its link due to the propagated state (Port 1 to Port 2). The

loss of link on the in the Port 1 to Port 2 direction. See Figure 5 for valid Link Mode congurations.

SW7: Pause “Off/On”

The Pause DIP-switch sets the ow control functionality for all ports on the module, including pause

mode advertisement, pause functionality, and half duplex back pressure. When the DIP-switch is in

the Pause “On” position, ow control functionality is enabled. When this DIP-switch is in the Pause

“Off” position (factory default), ow control functionality is disabled.

If Pause is On and the port is in half duplex, then half duplex ow control is enabled. When a port is

in half duplex ow control it generates a back pressure signal when internal buffer resources are low.

If Pause is On and the port is in full duplex, then full duplex ow control is enabled. When a port is in

full duplex ow control and internal buffering resources are low, a pause frame is generated to slow

down the trafc ow to the port.

SW8: MAC Learning “On/Off”

When this DIP-switch is in the “On” position (factory default), all ports on the module will learn the

source MAC address of each received packet and store the address so packets destined for the stored

addresses can be forwarded to the appropriate interface on the module. When the DIP-switch is in

the “Off” position, learning is turned off and all received packets are forwarded to all ports.

2) INSTALL STANDALONE MODULE AND CONNECT CABLES

Caution: Use proper ESD protection to reduce the risk of damage to your equipment.

a. The GX/T2 is available as a standalone module with integrated wall-mount brackets. Attach

the unit to a wall, backboard or other at surfaces. Make sure the unit is placed in a safe, dry

and secure location.

To power the unit using the AC/DC adapter, connect the AC/DC adapter to the AC outlet. Then

connect the barrel plug at the end of the wire on the AC/DC adapter to the 2.5mm DC barrel

connector (center-positive) on the chassis. Conrm that the unit has powered up properly by

checking the power status LED located on the front of the unit.

To power the unit using a DC power source, prepare a power cable using a two conductor

insulated wire (not supplied) with a 14 AWG gauge minimum. Cut the power cable to the length

required. Strip approximately 3/8 of an inch of insulation from the power cable wires. Connect

the power cables to the unit by fastening the stripped ends to the DC power connector. Connect

the power wires to the DC power source. The Power LED should indicate the presence of

power.

NOTE: If mounting with a safety ground attachment, use the safety ground screw at the

rear of the unit.

b. When using a GX/T2 SFP model, insert the SFP ber transceiver into the Port 1 SFP receptacle

on the GX/T2.

NOTE: The release latch of the SFP Fiber transceiver must be in the closed position

before insertion.

c. Connect the UTP port via a Category 5 or better cable to a 10BASE-T, 100BASE-TX or

1000BASE-T Ethernet device.

d. Connect an appropriate multimode or single-mode ber cable to the ber port of the installed

module. It is important to ensure that the transmit (TX) is attached to the receive side of the

device at the other end and the receive (RX) is attached to the transmit side. Single-ber (SF)

media converter models operate in pairs. The TX wavelength must match the RX wavelength

at the other end and the RX wavelength must match the TX wavelength at the other end.

3) VERIFY OPERATION

Verify the correct LED is illuminated based on the conguration of the port. Figure 6 and 7 on the next

page indicates the operation of the port based on the illuminated LEDs. If the 100 LED is illuminated,

the port is operating at 100Mbps. If the 1000 LED is illuminated, the port is operating at 1000Mbps

and if the 100 and 1000 LEDs are illuminated, the port is operating at 10Mbps.
