10/100 In-Line Link Aggregator Tap  
Introduction  
Thank you for choosing the most versatile monitoring Tap available today.  
Net Optics Link Aggregator Taps are an efficiency 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 traffic 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 num-  
ber of links covered by monitoring devices already installed.  
No Packets Left Behind  
The Link Aggregator Tap buffers and scans incoming traffic 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 traffic surges.  
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.  
Reliability  
For extra uptime protection, Net Optics Taps offer redundant power connec-  
tions. 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 flow of traffic 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

Carefully unpack the 10/100 In-Line Link Aggregator Tap and check for dam-  
aged or missing parts. The Link Aggregator Tap ships with the following:  
10/100 In-Line Link Aggregator Tap  
Two power cords  
Installation Guide  
In addition to the Port Aggregator, you should have ordered at least one SFP  
module. You may have also ordered an extended warranty. Carefully check the  
packing slip against parts received. If any part is missing or damaged, contact  
Net Optics' Customer Service immediately.

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 flashes 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 flow of traffic to the  
monitoring device should the first power supply fail. If the first 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 traffic from the connected network devices upon  
re-connecting to the Link Aggregator. This is to ensure that traffic 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.

10/100 In-Line Link Aggregator Tap  
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.
