Premium Stackable Gigabit Ethernet Switching for Advanced Edge Applications
The 3Com Switch 5500G-EI 24-Port is a premium stackable 10/100/1000 switch with Enhanced Image (EI) software for businesses running the most demanding network applications requiring the highest "five 9s" network uptime.

24 ports operate at 10/100/1000; four of these ports are dual-purposed with four SFP-based Gigabit ports. Expansion module slot offers additional Gigabit or 10-Gigabit Ethernet connectivity. The 10/100/1000 ports also provide Power over Ethernet (PoE), for distribution of power to other devices over the same cabling used for data.

The Switch 5500G-EI supports distributed, resilient 3Com XRN Stacking Technology with 48 Gbps stacking bandwidth (96 Gbps full duplex) and advanced Layer 3 (RIP / OSPF) routing, Layer 2-4 QoS, and rate limiting features.

This switch provides extensive security featuresSNMP v3, SSH, network loginand resilient hot-swap stacking for simplified management and monitoring.

All 3Com Switch 5500 products share the same operating system as our premium modular switches and routers, including the 3Com Switch 8800 and 7700. This permits you to manage an entire distributed switching and routing infrastructure from a single CLI or SNMP management platform such as 3Com Enterprise Management Suite or 3Com Network Director.

  • 20 in-line power 10/100/1000 ports; 4 dual-personality in-line power 10/100/1000 or SFP Gigabit ports; 1 expansion module slot.
  • Scalable stackable design with resilient stacking up to eight units high, or up to 448 Gigabit Ethernet ports (when outfitted with optional 8-port SFP-based expansion module).
  • 10-Gigabit Ethernet modules available, for interconnecting core and distribution switches.
  • Up to 192.0 Gbps switching capacity, 136.9 Mpps forwarding rate, maximum.
  • 48 Gbps stacking bandwidth (96 Gbps full duplex).
  • Multi-layer operation with static routes, RIP-based Layer 3 functionality, OSPF, and PIM-DM and PIM-SM.
  • 3Com XRN Stacking Technology provides for the creation of eight-unit stacks that offer chassis-like availability and resiliency over traditional aggregated-trunk configurations. The entire stack is managed as a single-IP management entity, with "masterless" sharing of critical routing information across all units for fast failure recovery.
  • Load-sharing and cross-stack trunking features help eliminate dropped packets, clear up traffic bottlenecks, and improve server availability.
  • Integrated distributed security enforcement.

  • Advanced, time-based Access Control Lists (ACLs) help safeguard key network resources from unauthorized access and data corruption.
  • User-based authentication and DES 56-bit or 168-bit encryption help secure Layer 3 protocols and management controls.
  • For flexible fiber connectivity, this switch supports up to two dual-mode Fast Ethernet SFPs 100BASE-FX and 100BASE-LX10 in the last two combo SFP ports of the switch; up to eight of these dual-mode SFPs are supported in the Switch 5500G 8-Port SFP module
  • Shared 3Com Operating System consolidates administrative control over the entire switching infrastructurecontributing to a more unified network environment and providing unparalleled edge-to-core visibility and control.
  • Built-in support for AC- and DC-powered operations enables you to leverage existing power schemes and cost-effectively extend power to the edge of the network.
