Improve performance across the network with this 24-port 10/100/1000 switch. This high-performance, compact, and affordable switching platform is ideal for a large server farm or for aggregating switches in a wiring closet. Its optional expansion module lets you deploy additional gigabit media such as 1000BASE-SX, 1000BASE-LX, and 1000BASE-LH70 (long-haul Gigabit Ethernet) in the same platform.
The SuperStack 3 Switch 4924 supports 3Com Gigabit Multilayer Switching software, which offers feature-rich Layer 2 functionality, Layer 3 switching for IP networks, and advanced traffic prioritization and security capabilities to accommodate the ever growing requirements of enterprise networks.

3Com XRN™ (eXpandable Resilient Networking) technology allows implementation of high availability configurations using two interconnected SuperStack 3 Switch 4900 family switches, scaling the connections to 48 wirespeed Gigabit Layer 3 switching ports (with purchase of optional 3Com XRN Interconnect Kit, or GBIC Fabric Interconnect with GMS Advanced Feature License)
Advanced Layer 2 and Layer 3 functionality—such as multicast filtering, enhanced QoS/CoS services, virtual LANs, and multilayer traffic classification and prioritization—provides network-wide traffic control
3Com-developed ASIC architecture delivers 56 Gbps multilayer switching capacity per unit, wire-speed performance across all ports, and a forwarding rate of more than 41 million pps
Layer 3 switching capabilities—such as OSPF, IP unicast using static routes, RIP/RIPv2, and CIDR—help enhance performance, provide network control and security, and enable routing between VLANs (OSPF available with purchase of GMS Advanced Feature License, 3C1770v4)
Support for high availability software features such as Link Aggregation using 802.3.ad, Resilient links, Spanning Tree and Rapid Spanning Tree (802.1w), seven groups of RMON, and e-mail alerts
Security features like RADIUS client support and Routed Access Control Lists protect sensitive network information and ensure that users have access to authorized resources
Optional 1000BASE-SX, 1000BASE-T, 1000BASE-LX and GBIC-based expansion modules deliver four ports of high-performance, feature-rich switching over copper or multimode fiber
