Premium Stackable Fast Ethernet Switching
for Advanced Edge Applications
The 3Com Switch 5500-SI 28-Port is a premium stackable 10/100 switch
with Standard Image (SI) 3Com OS software for businesses looking for
enhanced network security, performance and reliability.
24-ports operate at 10/100 speeds while an additional four active ports
can be customized using SFP modules for copper or fiber Gigabit uplinks
or integrated stacking.
SI models have dynamic Layer 3 (RIP) routing, Layer 2-4 QoS, and rate
limiting features. This switch provides extensive security features—SNMP
v3, SSH, network login—and 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.

|
Features |
- 24 10/100 ports, with 4 SFP slots.
- Scalable stackable design with
resilient stacking up to eight units high, or 384 Fast Ethernet
ports using 2 Gbps stacking bandwidth (4 Gbps full duplex).
- 12.8 Gbps switching capacity, 9.5
Mpps forwarding rate, maximum.
- 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 and RIP-based Layer 3 functionality.
- Integrated distributed security
enforcement.
- User-based authentication and DES
56-bit or 168-bit encryption help secure Layer 3 protocols and
management controls.
- Shared 3Com Operating System
consolidates administrative control over the entire switching
infrastructure—contributing 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.
- Available DC Redundant Power
Supply (RPS), designed by Eaton Powerware Corporation, a leading
provider of integrated power systems.
