C17715 3Com SuperStack 3 Switch 4900 XRN Kit.
HP XRN Interconnect Kit (JE927A)
Features & Benefits
XRN Technology for Local Connections
The XRN Interconnect Kit provides what is needed to connect two switches supporting this technology to be locally connected, typically running side by side in a single rack.
It consists of two modules, one for each switch, and a cable to connect them. Also provided is the minimum software (Version 3.x or higher) required to ensure units you may have purchased include the firmware to run this flavor of XRN.
XRN Technology Summary
XRN™, which stands for eXpandable Resilient Networking. It is patented, innovative 3Com technology that allows IT managers to build affordable networks that are highly resilient and deliver exceptional performance and flexibility. With XRN technology, multiple interconnected Gigabit switches behave as a single management switching entity. The units actively share the load in normal operation yet one will near-instantly recover all connections should the other unit or its connections have a failure. XRN is supported by the 3Com SuperStack 3 Switch 4900 for server aggregation and by the 3Com Switch 40×0 for building core networking. It is high resiliency without complexity
Economically leverage existing 3Com equipment for greater return on investment
Design highly fault-tolerant network infrastructures without added complexity or compromise in performance
Dramatic increase of core performance in excess of 70 Mpps across 48 switched Gigabit ports using XRN™ technology
Supports standards-based Link Aggregation using 802.3ad and LACP, enabling 3Com and non-3Com devices to take advantage of the benefits of XRN™ technology
Feature rich Layer 2 functionality such as VLAN tagging, Multicast Filtering, Spanning Tree and Rapid Spanning Tree (802.1w), 802.3ad LACP
Layer 3 switching for IP networks and enhanced QoS
RADIUS Client, Routed Access Control Lists, and Application Filtering enhance network security
Resilient fabric management via a single IP address
Fabric-wide configuration of all management, system, and port features eases fabric configuration and management
Mix-and-match switches to meet specific port and media requirements
