24x7 Secure Access and Monitoring
The USRobotics 10/100 Copper Tap, an inline non-directional full duplex device, provides 
an easy method to rapidly and effectively deploy analysis tools to observe and monitor 
10/100 BaseT traffic between two network devices. By design taps are totally passive, 
non-intrusive and invisible to the network making it ideal for traffic between critical 
network devices such as switches, routers and firewalls for real-time monitoring and 
analysis with security analyzers or probes. Permanent installations eliminate the need 
for interrupting networking connectivity to reinstall, but also guarantees network traffic 
still flows if the device loses power.  Redundant power solutions ensure network uptime 
even when the main power source is unavailable.   
Monitoring & 
Analysis
• Captures all traffic and delivers a copy to a tool for analysis
• 100% visibility into the network - including VLAN tags
• View all traffic on both sides of full duplex links
• Reduces degradation of  switch performance due to port mirroring
• View Layer 1 and 2 errors such as runts and CRC errors
• Full duplex monitoring
• Best method to measure network link’s performance
Network Stability
• Ideal for 24x7 permanent access - eliminating the need to connect tools each time a link needs to be
monitored
• Non-intrusive way to connect a network tool
• Fault-tolerant
• Passes all pairs
• Non-directional totally passive inline tap
• Minimize traffic delay through the tap
Secure
• Invisible on the network
• No single point of  failure*
Simple installation
• Plug and play
• Comes with convenient built-in rackmount or use an optional 1U rack mount kit for up to 3 devices.
• 10/100 BaseT compatible
• Standard RJ45 connectors
Reliable Power
• Redundant power supplies insure seamless monitoring even if  the main power source is unavailable
• In the event of  a power failure, the tap will continue to pass network traffic uninterrupted
• Supports Power over Ethernet (PoE) on network Ports
