4-Unit Rackmount Kit - MSRP $72.99

The USR TAP Rackmount Chassis holds up to four 4" TAPs in a standard 1U rack providing a space saving solution for multiple TAP installations.

Multi-purpose tap for aggregation, breakout, and span/regeneration.

The USR® Gigabit Ethernet Aggregation TAP eliminates SPAN port contention, oversubscription, and configuration errors with 3 different modes, simple installation, and reliable access to your gigabit ethernet segments.

In aggregation mode this TAP faultlessly combines and processes both the TX and RX streams of data into a single data stream. Improve visibility with two monitor ports sending identical copies of full-duplex data to separate network tools (analyzer, IDS, probe) for simultaneous monitoring and analyzing.

For dual-receive tools, breakout mode is available for individual TX and RX streams.

SPAN/Regenerate mode transmits 3 copies of incoming traffic for up to 3 tools. Ideal for security applications, including link failure propagation for HA designed networks, or anywhere you need non-intrusive dedicated access to your network links for advanced or consolidated monitoring.

USR4523 features | Monitoring and analysis

• Aggregation mode allows monitoring full-duplex traffic, even with single interface monitoring tools
• Breakout mode allows monitoring full-duplex traffic with RX and TX streams on separate monitoring ports
• SPAN/Regeneration mode sends copies to multiple tools to provide 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

• Fault-tolerant
• 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
• Link Failure propagation for High Availability designed networks ensures instant switch to the secondary link to maintain 100% uptime

The USR Gigabit Fiber TAPs provide an easy method to rapidly and effectively deploy analysis tools to observe and monitor traffic non-intrusively between two devices on a fiber network up to 100G. By design, fiber TAPs are totally passive, fault-tolerant, invisible to the network, with no power requirements so they will not affect network performance or integrity and can be trusted for permanent installations on a fiber network. These rock solid devices are ideal for real-time monitoring and analysis of full-duplex traffic between critical network devices such as switches, routers and firewalls and continue to pass errors that aren't seen using SPAN ports. Topology independent, the TAPs can be used for ATM, Gigabit, OC3-OC48, or SONET protocols and are available for both OS1-2 Singlemode and OM1-4 Multi-mode fiber networks.

Permanent inline monitoring and analysis | Monitoring & Analysis

• Captures and delivers a copy of all traffic to any analysis tool
• 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 not seen when performing network monitoring using SPAN ports
• Full-duplex monitoring
• Best method to measure network link's performance
• Great for network analysis and troubleshooting, IDS and monitoring applications

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
• Minimize traffic delay
• Fault-tolerant design

Secure & Reliable

• Passive access means no interference of network traffic
• Invisible on the network - no IP address means additional security
• No single point of failure
• Network traffic will continue to pass uninterrupted

Excellent Compatibility

• 50/50 split ratio
• Multi-mode model supports 1G, 10G, and 25G
• Single-mode model supports 1G, 10G, 25G, 40G and 100G
• Supports multiple topologies: Gigabit Ethernet, ATM, OC3-48, and SONET

Simple installation

• Plug and play
• No power required
• Connectors on front for easy access and operation
• Comes with convenient mounting tabs for use with the optional USR4522-RMK 4 unit 1U rackmount.
