Introduction
The
3Com Switch 5500-EI 28-Port is a premium stackable
10/100 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 while four additional SFP-based
ports operate at Gigabit speeds. The 10/100
ports also provide Power over Ethernet (PoE),
for distribution of power to other devices
over the same cabling used for data.
The
Switch 5500-EI supports distributed, resilient
3Com XRN® Stacking Technology and advanced
Layer 3 (RIP / OSPF) 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 in-line power 10/100 ports, for data switching
and PoE distribution using the same cabling;
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,
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.
#
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.
