Introduction
Thank you for choosing the most versatile monitoring Tap available today.
Net Optics Link Aggregator Taps are an efciency breakthrough for passively
monitoring multiple full-duplex links. Whether you are a novice or an expert,
this installation guide is designed to help answer any questions and to provide
a quick set-up reference.
Net Optics Link Aggregator Tap provides superior monitoring coverage while
leveraging monitoring resources. Providing trafc from multiple network
links, the Link Aggregator Tap combines up to four full-duplex 10/100BaseT
links (eight half-duplex data streams) into one, two or four GigaBit monitor
ports.
Installing a monitoring device in each segment of the network is often time
consuming and expensive. Restricted by tight budgets, security managers must
make compromises that leave portions of the network exposed to attacks.
Net Optics’ Link Aggregator addresses this challenge by increasing the number of links covered by monitoring devices already installed.
No Packets Left Behind
The Link Aggregator Tap buffers and scans incoming trafc from the network
ports on a round-robin basis. Buffer size and scan rate is optimized to ensure
that no packets are dropped and there is no bandwidth limitation on incoming
data streams. The buffers and the high bandwidth of GigaBit monitor ports
guarantee that no data is lost during trafc surges.
10/100 In-Line Link Aggregator Tap
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 extra 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 source.

Zero DelayTM - A Net Optics Breakthrough
Highly sensitive network locations can improve monitoring performance via
the innovative features of Net Optics Taps. If power is lost to other 10/100
Taps, the connected devices may introduce delays as they detect the power
loss and try to re-establish their link. Net Optics’ pioneering design ensures
that any loss of power to the Tap is transparent to the network and does not
affect the ow of trafc through the Tap – eliminating packet delay and loss as
potential security issues.
Cabling Guidelines
If connecting to Switches or Hubs, use CAT5e RJ45 cross-over cabling•
If connecting to routers or NICs, use CAT5e RJ45 straight-through cabling•

PWR 1/ PWR 2• : Main and Redundant Power. If the Tap is deployed with
both power supplies, both LEDs illuminate when the Tap is plugged in. If
an LED is off, this indicates that the corresponding power supply is not
connected or not functioning.
Activity Indicator• : When there is activity on the link, LED ashes green.
Link Indicator• : When a good link is established, the LED is a solid green.
Connecting to the Network
To connect to the network:
1. Connect Network Port 1 to the appropriate switch, server or router device
using a CAT5e RJ45 cable.
2. Connect Network Port 2 to the appropriate switch, server or router device
using a CAT5e RJ45 cable.

3. Repeat Steps 1 and 2 for the rest of the network ports of the Link
Aggregator Tap.
4. Verify that the Link Aggregator Tap Network Ports are cabled in-line
between two devices.
Note: ______________________________________________________________
The second power supply is available to support the ow of trafc to the
monitoring device should the rst power supply fail. If the rst power supply
is unavailable, the second power supply supplies all power for the Tap.

NOTE: _____________________________________________________________
At 10Mbps, if any of the network links are unplugged during operation, it
will be necessary to restart trafc from the connected network devices upon
re-connecting to the Link Aggregator. This is to ensure that trafc is properly
copied to the monitor ports and only applies to networks running at 10Mbps.
____________________________________________________________________
Connecting Monitoring Devices
1. Supply power to the Tap using the power supply adapter included
with the unit. Verify that the power LED illuminates.
2. Remove the SFP from its protective packaging.
3. Remove the temporary plug from Monitor Port 1.

4. Insert the SFP in the Monitor 1 Port until you hear it click into place.
5. Connect Monitoring Port 1 to the appropriate port on the monitoring
device. This will monitor all aggregated links connected to the network
ports.
6. If you are installing multiple SFPs, repeat Steps 1 through 4 for Monitor
Port 2.

Note: ______________________________________________________________
The 10/100 Link Aggregator is shipped with the following default dip-switch
settings. It is strongly recommended that you do not make any changes to
these settings, except when needed, and only to switches 2,4,5 and 6. If Switch
3, for example, is toggled to "on," the Link Aggregator will not get a valid
link. In the event that the aforementioned occurs, it will be necessary to return
the dip-switches to the default states and to power-cycle the unit.
