Technical specifications
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 SFP ports operate at Gigabit
speeds; four of these ports are dual-purposed with four 10/100/1000 ports. Expansion
module slot offers additional Gigabit or 10-Gigabit Ethernet connectivity.
Ports: 24 Gigabit SFP ports, 4 of which are dual-personality operating as SFP or auto-
negotiating 10BASE-T/100BASE-TX/1000BASE-T; RPS power port (-48 VDC); RJ-45
console port; 2 dedicated stacking ports; 1 optional module slot
- Last two combo SFP ports support up to two dual-mode Fast Ethernet SFPs
- Performance: 192.0 Gbps switching capacity, 136.9 Mpps forwarding rate, maximum
(with 2-port 10-Gigabit module); 107.1 Mpps forwarding rate, maximum (with no
optional modules)
- Stacking: Up to 8 switch units, 448 Gigabit ports, with 16 10-Gigabit ports; 3Com
XRN® Stacking linked in active/active load-sharing configuration via built-in dedicated
48 Gbps stacking ports 96 Gbps full duplex)

routing, RIPv1/v2, OSPF, ASIC Layer 3 forwarding, PIM-DM, PIM-SM, IGMP v1/v2
snooping, DHCP Relay
- Resiliency: IEEE 802.3ad LACP, hot-swappable switch units, DC RPS provides N+1
power redundancy, seamless failover between AC and DC modes
- Convergence: Weighted Round Robin/Fair/Strict Priority Queuing, IEEE 802.1p Class
of Service/Quality of Service (CoS/QoS), IPv6 classification, prioritization and filtering,
ingress/egress rate limiting, webcache-based bandwidth management

accounting; SSH; Access Control Lists; packet filtering; SNMP v3 encryption, IEEE
802.1X Network Login; authentication, VLAN autoinitiation and QoS profiling; multilevel
access privileges; administrative password recovery; management activity logs
- Operating system: 3Com Operating System; shared with 3Com Switch 8800, 7700
and Router 6000
- 3Com management: Intelligent Management Center (IMC)
- Other management: Web-based GUI, SNMP v1/2/3, telnet, CLI, SSH, RMON-1
(statistics, history, alarms, events), multiple software images, bank swap, statistics
gathering and reporting, remote polling/ping (unicast mode only), software
