FLEXIBLE, SECURE FIBER CONNECTIONS
The Switch 5500-EI FX is ideally suited for applications
where security is of paramount importance, or where
long cable runs are required. This switch provides
connections on fiber infrastructures that are almost
impervious to electronic eavesdropping because they
use optical transmission. The switch uses 100BASE-X
SFP transceivers for its 24 100 MB connections,
providing the flexibility of running any mix of
100BASE-FX multimode fiber (up to 2 km/1.2 miles)
or 100BASE-LX10 single-mode fiber (up to 10 km/6.2
miles).

PRIORITY FOR CONVERGED BUSINESS TRAFFIC
Next-generation traffic prioritization features—
including advanced policy-based Class of Service/
Quality of Service (CoS/QoS), eight priority queues,
committed access rates, bandwidth limiting and
filtering and more—identify and optimize delay-
sensitive traffic such as voice and video. To help
assure this optimization, switches can be configured
to automatically isolate voice traffic from 3Com and
other IP telephony systems within a voice-dedicated
VLAN.

UNIQUE AC/DC POWERED OPERATION
3Com Switch 5500 products are the first stackable
switches to support multiple power schemes right out
of the box, with a choice of AC, AC and DC, or DC
operation. Select models also support IEEE 802.3af
PoE, enabling power to be injected out to the edge of
the network without the need to install additional
wires or upgrade existing power supplies.

REDUNDANT POWER SYSTEM SUPPORT
All 3Com Switch 5500 models support a redundant

power system (RPS) connection.
RPS units provide these benefits:
› For PWR switches, an RPS can deliver more power
budget for IEEE 802.3af Power over Ethernet than
what the switches alone can provide. For example,
the Switch 5500G PWR 52-port switch has a PoE
power budget of 300 Watts, which means that less
than half of the ports can provide the full 802.3af PoE
power of 15.4 Watts. With an RPS providing power, all
48-ports can provide a full 15.4 Watts of PoE power.
