Installation Guide

Follow the simple steps outlined in this section of the guide to install and start
using the Metrobility 10/100 AutoTwister.

Unpack the AutoTwister and Accessories

Check that the following components have been included:

1

• 10/100 AutoTwister

• Power supply

• Power cord

• Four (4) rubber feet

Your order has been provided with the safest possible packaging, but ship­ping damage does occasionally occur. Inspect your order carefully. If you
discover any shipping damage, notify your carrier and follow their instruc­tions for damage and claims. Save the original shipping carton if return or
storage of the unit is necessary.

Choose an Appropriate Location

The 10/100 AutoTwister is intended for use in either ofce or industrial

2

environments. 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.

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

Set the Switches

MDI-II to MDI-X Switch

3

To eliminate the need for crossover cables, the 10/100 AutoTwister includes
an MDI-II to MDI-X switch for the twisted-pair port. This push-button
switch is located in the center of the front panel and allows setup in either

straight-through or crossover congurations. (See Figure 1.)

When setting the switch, observe the positioning of the following symbols:

• The parallel symbol (II) indicates a straight through or parallel connec-

tion. Switch is out. (default)

• The cross symbol (X) indicates a crossover connection. Switch is in.

Use the tables below as a guide.

DIP Switches

The 10/100 AutoTwister includes a set of six DIP switches located on the
back of the unit. (See Figure 2.) These switches allow you to select the

operational mode best suited to your network’s conguration.

When setting DIP switches, the ON position is when the DIP switch is

6 Installation Guide

pushed up toward the top of the unit. The OFF position is when the DIP
switch is pushed down toward the bottom.

Figure 2.

Auto-Negotiation Switch (AN1)

*

Switch AN1 controls the use of auto-negotiation on the copper port. To
enable auto-negotiation, set the switch ON. To disable this function, set the
switch OFF. By default, auto-negotiation is enabled.

When the copper port has auto-negotiation enabled, it advertises 100Mbps
full duplex capabilities. When auto-negotiation is disabled, the port’s duplex
is determined by the FD1 switch, and its speed is set by the 100M1 switch.

10/100Mbps Switch (100M1)

*

Switch 100M1 controls the speed setting for the copper port. If auto-ne­gotiation is disabled, the port speed will be the same as this switch setting,
where ON is 100Mbps and OFF is 10Mbps. The default speed setting is
100Mbps. When auto-negotiation is enabled, the 100M1 switch setting is
ignored.

Half/Full Duplex Switch (FD1, FD2)

Switch FD1 determines the duplex mode for the copper port if auto-negoti­ation is disabled. When auto-negotiation is enabled, the FD1 switch setting

is ignored. Switch FD2 determines the duplex mode on the ber optic port.

A port operates at full duplex when its FD switch is ON. It operates at half
duplex when its FD switch is OFF. The default is full duplex enabled.

*

*Changes to switches AN1, 100M1, FD1 and FD2 only come into effect after the power-cycle initialization.

Metrobility 10/100 AutoTwister 7

Link Loss Return Switch (LLR2)

The 10/100 AutoTwister incorporates Link Loss Return (LLR) functional-

ity as an aid in troubleshooting remote connections on its ber optic port.

When LLR is enabled, the loss of the inbound link pulses on the port stops
the transmission of outbound link pulses on the same port. For example, if
LLR is enabled on port 2 and its receiver (RX) stops detecting link pulses,
then port 2’s transmitter (TX) will stop sending link pulses. LLR is not ap­plicable to the copper port.

Link Loss Return is enabled on Port 2 when switch LLR2 is ON. The unit
is shipped with LLR disabled. Refer to Link Loss Return in the User Guide
section of this manual for more information.

Link Loss Carry Forward Switch (LLCF)

In addition to LLR, the AutoTwister supports Link Loss Carry Forward
functionality to help with troubleshooting remote connections.

Unlike LLR, which only applies to the ber port, LLCF affects both ports

on the AutoTwister. When LLCF is enabled, the loss of inbound link pulses
on a port stops the transmission of outbound link pulses on the opposite
port. For example, if LLCF is enabled, the loss of incoming link pulses at

Port 1 will stop the transmission of link pulses out of Port 2. Conversely, if
Port 2 stops receiving link pulses, Port 1 will not transmit link 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.

Use the following table to set the DIP switches to obtain specic modes of
operation. The conguration column lists the speed and duplex options for

Port 1 on the left and Port 2 on the right. “Auto” denotes that auto-negotia­tion is enabled.

Once power is applied to the unit, correct connectivity can be veried via

the link (LK) LEDs if a device is connected to the remote end of the cable.

Apply Power

Power is applied to the AutoTwister from the desktop power supply. The

5

power supply is equipped with an S760 hollow-type plug for insertion into
the DC jack located on the back panel and the standard IEC 320-type AC
power receptacle. All standalone AutoTwister standalone units use a 90­260V universal desktop power supply.

Connect the DC input jack located on the back of the AutoTwister before
connecting to the AC outlet.

Upon receiving power, the AutoTwister goes into normal operation mode
and automatically provides the appropriate signal translation between the
connected network segments.

Verify valid connections via the link (LK) LEDs on the AutoTwister’s front
panel.

Figure 4.

Metrobility 10/100 AutoTwister 11

If an additional extension cord is used to connect the power supply to the
outlet, follow the guidelines below.

While one end of the AC power cord can be tted with a plug standard for

the country of operation, the end that connects to the AutoTwister’s power

supply must have a female plug that ts this type of AC receptacle.

• AC 115V (North American): Use a UL-listed and CSA-certied

cord set consisting of a minimum No. 18 AWG, type SVT or SJT
three-conductor cord (15 ft. maximum length) and a parallel blade,
grounding-type attachment plug rated 15A, 125V.

• AC 230V (USA): Use a UL-listed cord set consisting of a mini-

mum No. 18 AWG, type SVT three-conductor cord (15 ft. maxi­mum length) and a Tandem blade grounding-type attachment plug
rated 15A, 250V.

• 240V (outside USA): Use a cord set consisting of a minimum No.

18 AWG cord and grounding-type attachment plug rated 15A,
250V. The cord set should have the appropriate safety approvals
for the country in which the AutoTwister is installed and marked

HAR.

LED Indicators

The Metrobility 10/100 AutoTwister provides several LEDs for the visible verica­tion of unit status and proper functionality. The LEDs can assist in troubleshooting
and with overall network diagnosis and management. There are separate transmit,
receive and link indicators for each port. The twisted-pair port also has a speed LED
and a duplex LED.

After power is applied to the AutoTwister, verify correct connectivity via the link
LEDs.

Factory Settings

This section describes the preset features on the 10/100 AutoTwister. These settings
cannot be changed.

Full-Duplex Flow Control

The AutoTwister supports ow control on each port in full duplex only. Full-duplex
ow control is provided to avoid dropping packets during network congestion. If

there is no buffer space available for incoming packets, the AutoTwister will issue

a PAUSE frame. Full-duplex ow control is only applicable to ports operating in

full duplex with auto-negotiation enabled. Additionally, during auto-negotiation, the
port’s link partner must advertise that it supports PAUSE frames.

For ports operating at half duplex, the AutoTwister does not support any type of ow

control. If there are not enough buffers available, incoming packets will be dropped.

Auto-Recovery

The AutoTwister includes an auto-recovery circuit that allows you to transparently
connect a pair of AutoTwister units between two network devices. This enables you
to design a redundant path between 10Mbps and 100Mbps devices, allowing both
end devices to lose link if any part of the connection is broken.

To activate auto-recovery, all of the following conditions must be met:

• Auto-negotiation is disabled.

• LLR is enabled.

• LLCF is enabled.

When auto-recovery is enabled, the AutoTwister attempts to establish the ber link

between two back-to-back units. Because LLR is enabled on both AutoTwister stand-

alone units, auto-recovery is needed to prevent the two ber ports from ending up in
a deadlock situation with each ber port waiting for the other to transmit rst. Auto-

recovery allows the deadlock to be broken by periodically sending out pulses from

the ber port allowing the AutoTwister to reestablish its ber link if the line is intact.

LLR is OFF LLR is ON

The ber optic ports of the Metrobility AutoTwister have been designed with LLR*

functionality for troubleshooting a remote connection.

When LLR is enabled, the ber port’s transmitter shuts down when its receiver fails

to detect a valid receive link. LLR is normally enabled on one end of the link and is
typically enabled on either the unmanaged or remote device. Setting LLR on both
ends of the link necessitates auto-recovery. See Auto-Recovery on page 17.

The diagram below shows a typical network conguration with good link status us­ing AutoTwister standalone units for remote connectivity.

If one of the optical conductors is bad (as shown in the diagram box below), the
AutoTwister with LLR enabled will return a no-link condition to its link partner. This
aids the administrator in determining the source of the loss.

*Units are shipped with the LLR function disabled (OFF).

The AutoTwister incorporates LLCF for troubleshooting remote connections. When
LLCF is enabled, the ports do not transmit a link signal until they receive a link
signal from the opposite port.

The diagram below shows a typical network conguration with good link status

using Metrobility AutoTwister standalone units for remote connectivity. Note that
LLCF is enabled as indicated in the diagram below.

If a connection breaks, the AutoTwister standalone units carry that link loss forward
to the switch/hubs which generate a trap to the management stations. A network
administrator can then determine the source of the problem.

A typical application of the 10/100 AutoTwister is to use it in pairs to extend a net­work’s reach between two distant devices.

In this back-to-back setup, it may be desirable to see the entire link down if any of
the connecting segments fails. This means that both copper ports must relay a no link
condition to the switch/hub when any of the cables is broken.

For proper operation in this conguration, auto-recovery must be enabled. In the

standalone AutoTwister, auto-recovery is enabled only when all of the following
switches are set as indicated:
AN1 = disabled (OFF) LLR2 = enabled (ON) LLCF = enabled (ON)

Because LLR is enabled on both units, auto-recovery is required to prevent the two

ber ports from ending up in a deadlock situation, with each waiting for the other to
transmit rst. Auto-recovery allows the deadlock to be broken by periodically send­ing out pulses from the ber port forcing the AutoTwister to establish its ber link if

the line is intact.

The diagrams below show how the two switch/hubs are alerted to a broken ber

cable. Notice that both LLR and LLCF must be enabled under this condition.

A set of four AutoTwister standalone units can be used to provide the redundancy
necessary to ensure that data from a 100Mbps device reaches its destination in a
10Mbps device, as illustrated in the diagram below. In this example, the main link,
which includes the AutoTwister standalones A1 and A2, must be seen as a single
connection. If any of the cables in the main link fails, both switch/hubs must be noti-

ed of the failure so they can activate the backup link, which includes AutoTwister

units B1 and B2.

Since the entire main link must appear
down if any of its connecting seg­ments fails, the copper ports of Auto­Twister standalone A1 and A2 must
be able to indicate a no-link condition
to their corresponding switch/hubs.
To do this, auto-recovery must be
enabled on both AutoTwister units.

To enable auto-recovery on the
AutoTwister standalone units, make sure that on each unit AN1 is disabled, LLR2 is
enabled, and LLCF is enabled.

The diagram below illustrates how the two switch/hubs are alerted to a broken ber

cable in the main link, thus activating the backup link with AutoTwister standalones
B1 and B2.

Sequence of events:

• AutoTwister A1 stops transmitting

data to AutoTwister A2.

• AutoTwister A2 senses the loss

of link and stops transmitting link
pulses to AutoTwister A1 and the
10Mbps switch/hub.

• AutoTwister A1 receives the no

link condition and stops transmit­ting link pulses to the 100Mbps
switch.

• The 100Mbps and 10Mbps switch/hubs detect that the main link is down and

switch trafc to the backup link.

• Trafc resumes via the backup path with AutoTwister standalone units B1 and B2.

• Because auto-recovery is enabled, AutoTwister standalone units A1 and A2 try to

reestablish the ber link by periodically sending out pulses from their ber ports.
