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 .
