The 3Com 3CR17250-91-US is a stackable 5500G-EI Gigabit Ethernet Switchg for customers Edge Applications .  The 3Com Switch 5500G-EI 24-Port 10/100/1000 switch comes with Enhanced Image software for guaranteed business uptime.  The 3Com 3CR17250-91-US has 24 ports that operate at 10/100/1000; 4 of these ports are dual-purposed with 4 SFP Gigabit ports. The switch has additional expansion module slots offering additional Gigabit or 10-Gigabit Ethernet connectivity.  The 3Com 3CR17250-91-US supports distributed 3Com XRN Stacking Technology supporting 48 Gbps stacking bandwidth (96 Gbps full duplex) and advanced Layer 3 (RIP / OSPF) routing, Layer 2-4 QoS, and rate limiting features.

The 3Com 5500G-EI switch provides security features e.g. SNMP v3, SSH, network login and resilient hot-swap stacking making network management and monitoring easy.

All 3Com 3CR17250-91-US 5500G-EI Switch uses the same OS as the premium modular switches and routers, including the 3Com Switch 8800 and 7700. The cross hardware OS allows network administrators to manage an entire distributed switching and routing campus using a single CLI or SNMP administrator management utility such as 3Com Enterprise Management Suite or 3Com Network Director.

3Com 3CR17250-91-US 5500G-EI Overview and specifications

• 20 10/100/1000 ports; 4 dual-personality 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).
• Wirespeed performance across all ports within a stack delivers optimal throughputs and bandwidth for business-critical data and high-speed communications.
• 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.
• Upgradeable to Power over Ethernet (PoE) capabilities with a field replaceable PoE-enabled power supply.
