Optimized OSM

The 3Com Switch 5500G Open Services Module (OSM) provides up to 56 gigabit layer 2/3/4 switched ports per switch and up to 448 gigabit ports per stack. The OSM is equipped with four dual-purpose ports on each switch providing either 10/100/1000 or small form-factor pluggable (SFP) fast/gigabit Ethernet connectivity. In addition, the 5500G: offers optional 1- and 2-port 10-Gigabit and 8-port SFP Gigabit modules for links to the network core; can be stacked eight units high and managed as a single-IP entity; delivers wirespeed and line-rate performance on all ports; and, offers OSPF and multicast routing, 3Com XRN stacking technology, and IEEE 802.3af Power over Ethernet. The module prioritizes converged network traffic with advanced CoS/QoS and other features to ensure high levels of service for latency-sensitive applications, consolidates administrative control, and enhances core-to-edge visibility with an operating system shared with 3Com modular switches and routers. 3Com Corp., Marlborough, Mass.
