Cost Effective
Delivering Power over Ethernet means
electricity and data are provided over a single Ethernet cable, resulting
in significant cost savings when deploying devices such as IP phones,

3Com Baseline Plus Switch 2900 Family
The voice-ready 3Com Baseline Plus Switch 2900 Family are web-
managed Gigabit switches that deliver enterprise-class features,
customized and priced for small- and mid-sized organizations. With
an easy-to-use switch interface, advanced features (VLANs, Access
Control Lists, IEEE 802.1X authentication and Rapid Spanning Tree),
20, 28 or 48 10/100/1000 ports, and available PoE support, these
switches are a cost-effective way to provide a converged network.

Traffic Prioritization and Auto-Voice VLAN
Traffic prioritization and automatic assignment of VoIP traffic to
dedicated VLANs help ensure that critical time-sensitive traffic gets
the priority needed for quality communications.

Power over Ethernet
Baseline Plus Switch 2900 PWR models provide inline power to
attached devices—access points, Voice over IP (VoIP) phones, IP security
cameras, etc.—via industry-standard IEEE 802.3af PoE over a single
Ethernet cable, resulting in significant deployment cost savings.

No Switch Setup Required
These switches are operational straight out-of-the-box; as long as
default settings are acceptable, there is no need to configure the
switch. If desired, the switches can be configured using a web
browser or SNMP management software, and are fully supported
when using 3Com Network Supervisor and Network Director.
