US Robotics USR4504 overview

  • 1Description

Accessing and monitoring network traffic is essential to keep the network operating smoothly and the 1G Variable 4-Port Aggregator & Regenerator from US Robotics is equipped to expand an existing SPAN (Port Mirror) or TAP port monitoring capabilities. This network aggregator and regenerator can be attached to a SPAN port to analyze network traffic or admins can utilize the TAP (Test Access Point) method to analyze network traffic and gain access to both send and receive data streams simultaneously.

This network device comes equipped with a single Gigabit Ethernet unidirectional input port, a single Gigabit Ethernet unidirectional output port, dual Gigabit Ethernet input or output ports, and two power inputs. Network administrators can also take advantage of dedicated LED indicators to see power and port status of the aggregator/regenerator.

Monitoring & Analysis

View entire full duplex conversations using single interface monitoring tools
Improve visibility into the network - including VLAN tags
Decrease reliance on switch resources for network management visibility
Eliminate SPAN port contention, oversubscription, and configuration errors
Easily share monitor ports for improved monitoring without maintenance windows
Ideal for Intrusion Detection System (IDS) applications

Aggregating Data (3:1 Mode)

Combine multiple network links or channels from TAP, SPAN, or mirror ports into one stream
Monitor network traffic from up to three different sources through a single-interface monitoring tool
Visibility into complete network conversations, including full-duplex conversations
Provide security or analysis to a larger part of the network by allowing single port device access to traffic from multiple points in the network

Regenerating Data (3:1 Mode)

Duplicate traffic from a single Tap or SPAN port to up to 3 monitoring tools
Access to the same links for system redundancy, testing and advanced monitoring applications
Expand access to data across company assets and provide a wider variety of data to each department
Improve overall switch performance by removing port mirror degradation while freeing valuable ports


No MAC or IP settings on the traffic ports makes the device invisible to the network
Unidirectional passive traffic makes 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

Simple Installation

Simple DIP switch configuration setting
Plug and play (no configuration or management settings after switch is set) means simple and fast installation
Deploy tools immediately without impacting production network
Auto negotiates settings for 10/100/1000 Mbps network speeds
All ports support Power over Ethernet (PoE) for spaces that may have limited power
Comes with convenient attached rack mount bracket for use with the optional 1U rack mount kit for solutions of up to 3 devices
