US Robotics USR4503 overview

  • 1Description

Monitor both TX and RX data streams using the 10/100/1000 Copper Aggregation Tap from US Robotics. With this network tap you can help avoid SPAN contention which occurs when too many monitoring devices are being utilized simultaneously. The Copper Aggregation Tap also helps to prevent oversubscription in which ingress bandwidth is greater than egress bandwidth. To accomplish this the tap has the ability to combine both TX and RX streams into a single data stream for full duplex monitoring. Data streams can also be divided using half duplex monitoring allowing two ports to see full line rate traffic.

With fault tolerance and the removal of mirror degradation users benefit from improved network stability. Additionally, this tap has the ability to improve network troubleshooting allowing admins to see both sides of the full duplex conversation while combining both streams into a single trace file. With plug-and-play support and auto negotiation this Copper Aggregation Tap can be installed into various network configurations with little to no setup required.

Monitoring & Analysis

Full duplex monitoring, even with single interface monitoring tools
Half duplex monitoring allows two monitoring ports to see full line rate traffic
Regeneration to multiple tools provides access to the same links for system redundancy, testing and advanced monitoring applications
Improved visibility into the network - including VLAN tags
Ideal for Intrusion Detection System (IDS) applications

Aggregating Data

Monitor all network traffic from two different sources
Improve network troubleshooting by viewing both sides of a full duplex conversation
Combine both directions of a full duplex data stream in a single trace file
Allows flexibility of monitoring devices, including the option to revert to traditional full duplex dual channel data capture, utilizing single NIC probes for advanced monitoring or hardware reduction

Network Stability

Ideal for 24x7 permanent access - Deploy tools or utilize tap ports immediately without network traffic interruptions or the need for maintenance windows
Eliminate SPAN port contention, oversubscription, and configuration errors
Improve overall switch performance by removing port mirror degradation while freeing valuable ports

Simple Installation

Plug and play means simple and fast deployments
Auto negotiates settings for 10/100/1000 Mbps network speeds
Single network break for permanent installation
Comes with convenient attached rack mount bracket for use with the optional 1U rack mount kit for up to 3 devices


Unidirectional and invisible to other devices on the network making it impossible to access or infiltrate connected monitoring and analysis tools


Redundant power supply option ensures seamless monitoring even if the main power source is unavailable

To eliminate power as a single point of failure two power supplies must be used. The second power supply must be connected to a different external power source circuit than the first power supply. Additional power supplies may be sourced using the specifications provided
Inline design allows network connectivity in the event of a power failure
