Introduction
Net Optics 8x1 Regeneration Taps solve the key physical layer challenges of
multi-device network monitoring. For a better picture of network health, these
Taps connect up to eight different network management and security devices
at any single network location or two switch Span ports.
One Tap, No Idle Resources
Keep your intrusion detection and prevention systems, forensic trafc
recorders, protocol analyzers, RMON probes, and other security and
performance monitoring devices productive with a single Regeneration
Tap. Maximize resources and save on access points when multiple devices
can monitor link trafc simultaneously through a single Regeneration Tap.
Secure, passive access for multiple devices simply means a better return on
monitoring investments.
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.
Reliability
For superior uptime protection, Net Optics 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.
8x1 Regeneration Taps
Any Media
The RG-800 family of Regeneration Taps includes models for any network
media: 10G, 1G, and 110/100/1000; copper and ber; singlemode (SM) and
multimode (MM); inline and Span.
SFP Monitor Ports
All ber models have SFP (1G) or SFP+ (10G) cages for monitor ports,
enabling tools with any type of ber or copper media to be attached to the
Regeneration Tap outputs. (10G models support only 10G SFP+ transceiver
modules; they do not perform data rate conversion to 1G SFP transceivers.)
1
Inline or Span Ports
Models are available for either inline or Span deployments. Inline models
tap one link and create eight copies of the trafc traveling in one direction
on the link, plus eight copies of the trafc traveling in the other direction. A
monitoring tool with two NICs has visibility of the full duplex trafc at full
link bandwidth.
Span models act as two independent regeneration functions, with eight copies
created for the trafc from two separate Span ports or external taps.

Note: ________________________________________________________________
Each AC or DC power source should be independent of the other in order to
have power redundancy. If you do not require power redundancy, the unit can
be operated with a single power cord connected to a single AC or DC power
source. In this case, either AC or DC power connector on the rear of the unit
can be used for the connection.

LED Indicators
• Power LEDs: Each LED illuminates to show that power is being sourced
by one of the power supples.
• Link LEDs: For copper models, a LED on the right corner of each RJ45
illuminates when a link is established. The Link LEDs for ber network
ports are located in the top two positions in the stack of four LEDs to the
left of the network ports.
• SFP Present LEDs: The left side LED above each SFP/SFP+ cage
illuminates when a module is properly plugged in. The right side LED
about the cage is not used.
• Activity LEDs: For copper models, a LED on the left corner of each RJ45
connector ashes when there is activity on the port.
• Link Speed Indication: For 10/100/1000 copper ports, the color of the
Link LED is amber if the link speed is 10 Mbps, yellow for 100 Mbps, and
green for 1000 Mbps. On the ber models, bottom two LEDs in the stack of
four LEDs to the left of the network ports indicate whether the model is for
10 Gbps (second-from-bottom LED) or 1 Gbps (bottom LED) link speed.
Link Speed Setting
For 10/100/1000 copper interface models, the link speed and duplex mode
are set by pressing the mode change button. The button is recessed to prevent
accidental activation; use a pen tip or straightened paper clip so press it. Each
time you press the button, the mode changes. Press it repeatedly until you
reach your desired operating mode as indicated in the speed and duplex LEDs.
The modes and LED indications are illustrated below.

Connecting Power
Use the following procedures to safely connect AC or DC power to the unit.
Caution: ____________________________________________________________
For AC models, use the AC power cords supplied with the product. If you
use other AC power cords, they should have a wire gauge of at least 20 and
a 230VAC 1A rating. Be sure to use a three-prong cords and connect them to
sockets with good earth grounds.
For DC models, you must supply your own power cables. DC power cables
should have a wire gauge of at least 18 and a 72VDC 2A rating. Always
connect the earth grounds rst, and keep the earth grounds connected
whenever you are working on the device. When disconnecting the device from
DC power, remove the earth ground connections last.
______________________________________________________________________
To connect AC input power on AC models:
1. Connect the ground stud near the center of the rear panel to a good earth
ground. Usually this will be the same as the equipment rack ground.
2. Connect one of the AC power cords to one of the AC power connectors on
the rear panel.
3. Install a power supply clip over the head of the AC power cord to keep it
from accidently being unplugged from the AC power connector.
4. Plug the other end of the cord into an AC power source.
5. Push the "1" side of the power switch immediately above the power
connector to activate power.
6. Repeat Steps 2 to 5 for the other AC power source. Be sure to plug it into
an independent power circuit for power redundancy.
7
8x1 Regeneration Taps
To connect DC input power on DC models:
1. If you have not already done so, unpack the Regeneration Tap and verify
that you have appropriate DC power cables. You also need a Phillips
screwdriver to complete the installation.
2. If present, remove the protective covers from the DC power terminal
blocks.
3. Connect an earth ground lead to the terminal labeled with the ground symbol
(
), which is the left-most terminal, on both DC power terminal blocks on
the rear of the chassis. Use the screwdriver to tighten the connections. Also
connect the earth ground to the ground stud near the center of the rear panel.
4. Connect one of the DC power cables to one of the DC power terminal
blocks on the rear panel. Connect the negative (-48VDC) side of the cable
to the terminal labeled with the minus symbol (—) and the positive (0V)
side of the cable to the terminal labeled with the plus symbol (+). The
minus terminal is in the center and the plus terminal is on the right. Use
the screwdriver to tighten the connections.
5. Repeat Step 4 for the other DC power cable, connecting it to the remaining
DC power terminal block on the rear panel.
6. Carefully connect the other ends of the DC power cables to two -48VDC
power sources. If possible, turn off the power to the power source while
you are making these connections. Be sure to connect the positive sides
of the cables to the positive (plus) sides of the power sources, and the
negative sides of the power cables to the negative (minus) sides of the
power sources.
Installation in a Restricted Access Location in Finland
and Norway
Because of concerns about unreliable earthing in Finland and Norway,
this equipment must be installed in a Restricted Access Location (RAL) in
these countries. An RAL is dened as an access that can be gained only by
trained service personnel who have been instructed about the reasons for the
restricted access and any safety precautions that must be taken. In these cases,
the use of a tool (such as lock and key) or other means of security is required
for access to this equipment.
8
Connecting to the Network
1. Connect Network Port A to the appropriate switch Network or Span port
using a an appropriate cable.
2. Connect Network Port B to the appropriate switch Network or Span port
using an appropriate cable.
3. Check the Link and Activity LEDs to verify that the Regeneration Tap
is receiving trafc into the Network ports. For inline models, verify that
trafc is passing between the devices on both sides of the Regeneration Tap.

Connecting to the Monitoring Devices
1. If you have a ber model, install the appropriate SFP or SFP+ transceiver
modules in the Monitor ports. (You need to install modules only in ports to
which you will be connecting monitoring tools). Push each module in until
you hear a click and see the SFP Present LED above the port illuminate.
2. Connect any Monitor A port to the appropriate monitoring device using an
appropriate cable. The device will monitor Network trafc being received
at Network A port over this cable.
3. Connect any Monitor B port to another NIC on the same monitoring device
using an appropriate cable. The device will monitor Network trafc being
received at Network B port over this cable.
4. Connect other monitor devices to the remaining monitor ports as desired.
All of the Monitor A ports mirror the trafc being received at Network
A, and all of the Monitor B ports mirror the trafc being received at
Network B.

Note: _______________________________________________________________
On inline models, if trafc is passing between the devices on both sides of
the Network ports but no trafc can be seen on the monitoring ports, the
cables plugged into the Network ports may have TX and RX reversed. To x
this condition, reverse the TX and RX connections on BOTH Network A and
Network B ports. If you reverse the connections on only one of the ports,
trafc will not be able to pass between the devices.
