Installation Guide for Gigabit TX/SX Tap
Introduction
Net Optics GigaBit TX to SX Tap simplifies connecting FX fiber monitoring
and.security.devices.to.GigaBit.copper.network.links .Convert.TX.to.SX.and.
tap.into.the.link.with.one.device,.reducing.cost.and.complexity.at.the.same.
time .GigaBit.TX.to.SX.Taps.support.passive.monitoring.of.GigaBit.links.at.
speeds.at.1000.Mbps
Transparent Access
GigaBit.TX.to.SX.Taps.establish.permanent.passive.access.ports.without.
introducing.a.point.of.failure.or.disturbing.other.network.connections .These.
passive.Taps.deliver.full-duplex.monitoring.with.zero.impact.on.network.traf-
fic around the clock.
Security and Visibility
Without.an.IP.address,.monitoring.devices.are.isolated.from.the.network,.
dramatically.reducing.their.exposure.to.attacks .However,.the.monitoring.
device connected to the Tap still sees all full-duplex traffic as if it were in-line,
including.Layer.1.and.Layer.2.errors
Simply Plug It In
Full-duplex.monitoring.is.a.snap.with.supplied.cables .All.networking.and.
monitoring.cables.necessary.for.plug.and.play.deployment.are.included.with.
the.Tap
Reliability
For.extra.uptime.protection,.Net.Optics.GigaBit.TX.to.SX.Taps.offer...
redundant.power.connections .Should.the.primary.power.source.fail,.the.Tap.
automatically.switches.to.the.backup.power.source .Power.LEDs.on.the.front.
of.the.Tap.indicate.the.current.power.source.–.even.if.power.is.lost.and.reap-
plied, there is always zero delay to network traffic.
Key Features
Passive, Secure Technology
•. Provides.passive.access.at.speeds.at.1000.Mbps.without.data.stream.
. interference.or.introducing.a.point.of.failure
• Access GigaBit copper links with SX fiber devices without a separate
converter
•. Permanent.in-line.installation.without.affecting.network.performance

Connecting a GigaBit TX to SX Tap to the Network
.
1 .Unpack.the.Tap.and.verify.that.you.have.all.components,.and.obtain.the.
required.cables.needed.to.successfully.install.the.unit
2 .Connect.Network.Port.A.to.the.appropriate.switch,.server.or.router.using.a.
CAT5E RJ45 straight-thru cable. This will act as your DCE interface.
3 .Connect.Network.Port.B.to.the.appropriate.switch,.server.or.router.using.a.
CAT5E RJ45 straight-thru cable. This will act as your DTE interface.
4. Verify that the Tap Network Ports are cabled in-line between two devices.
Link Fault Signaling
. The.Tap.negotiates.separately.with.each.side.of.the.full-duplex.link,..
detecting.if.either.side.fails .In.the.event.of.a.failure,.the.Tap.ceases.nego-
tiation.with.the.remaining.side,.enabling.a.clean.fail-over.to.a.redundant.
network connection (if one is available).

Connecting a GigaBit TX to SX Tap to the Monitoring
Device
1 .Supply.power.to.the.Tap.using.the.2.redundant.power.supplies.included.
with the unit. Verify that the Power LED illuminates.
2 .Using.a.Net.Optics.Custom.Monitor.Cable,.connect.the.single-duplex.end.
to.the.Tap.Monitor.Port.A/B
3 .Connect.the.twin-duplex.end.of.the.cable.labeled.DCE.into.the.appropriate.
monitoring.device.port.to.monitor.the.DCE.link .
4. Connect the other twin-duplex end to the appropriate monitoring device
port.to.monitor.the.DTE.link .
5 .Compare.the.LEDs.on.the.Tap.to.the.chart.below.to.verify.correct.setup:.
PWR1: Power 1. This LED illuminates (Green) when device is powered
up
PWR2: Power 2. This LED illuminates (Green) when redundancy is .
powered.up
LK: Link. This LED illuminates (Green) when link is established with
another.device.
Tx: Transmit. This LED illuminates (Green) when UTP port is transmitting
a.signal .
Rx: Receive. This LED illuminates (Green) when UTP port is receiving a
signal .
Additional GigaBit TX/SX Tap LEDs are located in the upper left and
right hand corners of the RJ45 connectors for Port A and Port B
•. Link Indicator: Located.in.the.upper.right.hand.corner .If.a.good.link.is.
established,.the.LED.illuminates.a.steady.green .If.there.is.current.activity.
on this link, the LED flashes.
Note: The SC connectors on the Custom Analyzer Cable contain
RX connections only.
