Introduction
Net Optics GigaBit TX to SX Tap simplies connecting FX ber 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-
c 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 trafc 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
Installation Guide for Gigabit TX/SX 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 trafc.
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 ber 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 negotiation 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 ashes.
Note: The SC connectors on the Custom Analyzer Cable contain
RX connections only.
