Overview

Sleek, compact, and rich in features, Metrobility’s 100Mbps Delta Class “twister” looks as impressive as it operates. Designed for desktop use in any modern office, the durable “twister” meets strict US and international EMC regulations. This innovative device allows you to convert from copper to fiber, extend copper-based network distances up to 100km, and test the integrity of the fiber line using remote loopback on the fiber port. New features include a wall mounting option, automatic MDI-X/MDIII capability, highly visible LEDs on the top, and built-in cable management and protection.

To optimize your Fast Ethernet network, the “twister” provides seamless operation in full- and half-duplex environments. Full signal restoration ensures accurate data transmission throughout the network. The “twister” incorporates both Far End Fault and Link Loss Carry Forward, two troubleshooting functions to help identify the loss of a remote network connection.

On select models, bidirectional wavelength division multiplexing (BWDM) offers an interface that carries two separate channels in different directions through a single strand of fiber. BWDM eliminates the need to install a second fiber and effectively doubles the fiber capacity on existing fiber cables.

Installation Guide

Follow the simple steps outlined in this section to install and start using the Metrobility 100Mbps Delta Class “twister” media converter.

Unpack the “twister” and Accessories

Check that the following parts are included in your box:

• 100Mbps Delta Class “twister”

• Power supply

• Power supply cord (North American shipments only)

• Four (4) rubber feet Your order has been provided with the safest possible packaging, but

shipping damage occasionally does occur. Inspect your order carefully. If you discover any shipping damage, notify your carrier and follow instructions for damage and claims. Save the original shipping carton if return or storage of the unit is necessary.

Attach the Rubber Feet

The “twister” is shipped with four rubber feet located on the black adhesive strip. To install the rubber feet, first turn the “twister” upsidedown. Peel the feet from the adhesive strip, then attach one foot to each circular indentation on the unit. This provides an air gap which helps to cool the unit, and also adds stability for desktop operation.

If you are stacking the “twister” on top of another unit, the rubber feet must be attached to the bottom of the “twister”.

Choose an Appropriate Location

The “twister” is intended for use in either an office or a residential environment. The unit must be located within six (6) feet of the AC power source being used and placed as far away as possible from electrical noise generating equipment such as copiers, electrostatic printers, and other motorized equipment. If exposed twisted-pair wiring is used nearby, the wiring should be routed as far away as possible from power cords and data cables to minimize interference.

Installation Guide 5

The unit may be oriented in any manner which allows you to make the physical connection to the power supply and leaves a minimum of six (6) inches of space for proper ventilation.

Wall Mounting

The “twister” requires no additional hardware for wall mounting. After selecting an appropriate place for installation, simply align the 1/4" keyhole opening on the bottom of the unit to a screw (6-32 maximum head size) or wall anchor. Once you have it positioned properly, make sure the device is attached securely.

Set the Switches

The “twister” provides a set of six DIP switches located on the back panel. These switches allow you to select from several modes of operation. The default settings are shown below.

Link Loss Carry Forward Switch (LLCF)

The “twister” incorporates Link Loss Carry Forward (LLCF) functionality as an aid in troubleshooting remote connections. When LLCF is enabled, the loss of inbound link pulses on a port stops the transmission of outbound link pulses on the enabled, the loss of incoming link pulses at sion of link pulses out of pulses,

Link Loss Carry Forward is enabled on both ports when switch LLCF is ON. The unit is shipped with LLCF disabled. Refer to Link Loss Carry

Forward in the User Guide section of this manual for further details.

Far End Fault Switch (FEF)

The “twister” supports Far End Fault functionality to detect the loss of link by the remote unit’s fiber port receiver.

FEF is only applicable to the fiber port. When FEF is enabled on a port, the loss of the inbound link pulses on that port generates an alarm, which is sent out the port’s transmitter. FEF also enables a port to read the alarm. To function properly, the FEF setting on both the local and remote “twister” must be the same.

6 Metrobility 100Mbps Delta Class “twister”

For example, if FEF is enabled on both units and the remote unit’s fiber receiver (RX) stops detecting link pulses, then its fiber transmitter (TX) will send an alarm. The local “twister” will receive the alarm and report it through its fiber port FEF LED, which will turn amber. No alarm will be issued if FEF is disabled on the remote unit. The FEF LED will not turn amber if FEF is disabled on the local “twister” because it will not be able to detect the alarm.

Far End Fault is enabled on Port 2 when switch FEF is ON. The unit is shipped with FEF disabled. Refer to Far End Fault in the User Guide section of this manual for more information.

Auto-Negotiation Switch (AN1)

Switch AN1 controls the use of auto-negotiation on the copper port. Autonegotiation determines whether the port operates at half or full duplex. When AN1 is enabled, the copper port will advertise full duplex capabilities to its connected device, if the duplex switch, FD1, is enabled. The port will advertise half duplex capabilities if FD1 is disabled. If AN1 is disabled, the duplex switch will determine the port’s duplex mode. By default, auto-negotiation is enabled.

Duplex Switch (FD1)

Switch FD1 sets the duplex mode for the copper port when auto-negotiation is disabled. The copper port operates at full duplex when FD1 is enabled; and it operates at half duplex when FD1 is disabled. If autonegotiation is enabled, the FD1 switch setting will determine whether the port advertises full or half duplex (refer to Auto-Negotiation above). The default is set to full duplex enabled.

Copper Port Configuration Table

Use the table below to set the duplex and auto-negotiation DIP switches to obtain specific modes of operation for the copper port.

Disable Loopback Switch (DSLB)

This switch determines the response of the fiber port when it receives the remote loopback command. If the DSLB switch is enabled, the port will ignore all remote loopback commands. When the switch is disabled, the port will permit remote loopback to occur. By default, the response switch is disabled, which allows remote loopback.

Installation Guide 7

Remote Loopback Switch (RLBK)

The remote loopback switch allows you to test the fiber connection between a Metrobility Delta Class “twister” and a remote Metrobility x133 unit. Enabling the switch sends a loopback request to the remote fiber port. To run the loopback test properly , the following conditions must be met:

• The remote unit must be a Metrobility x133 standalone converter or line card.

• The DSLB switch on the remote unit must be disabled.

If the conditions are satisfied, the remote loopback sequence will begin. The remote fiber port will go into loopback mode. Next, the local “twister” will generate a test pattern that is sent to the remote unit and then looped back. The local “twister” will read the returned data to verify proper transmission. The LB LED on the local “twister” will indicate whether the test passed (green) or failed (amber). Refer to Remote Loopback for further information.

If the two conditions for remote loopback are not met, the remote loopback test will always fail. By default, remote loopback is disabled.

Connect to the Network

The Metrobility 100Mbps Delta Class “twister” offers the ease of plugand-play installation. The overhang extension provides built-in protection for the two cable connectors.

When making network connections with the Metrobility “twister”, grasp the end of the cable with your index finger on the top of the connector and your thumb on the bottom, as shown in the illustration below. For easier installation, insert the copper cable to the “twister” before connecting the fiber.
