OVERVIEW
The "smart" voice-ready 3Com
®
Baseline Plus Switch
2900 Gigabit Family delivers Layer 2 enterprise-class
Gigabit switching solutions along with layer 3 static
routes, customized and priced for small and mid-sized
organizations.
These managed switches offer tremendous value to
small and medium businesses looking for a low cost
solution who need a level of control over their network
not offered by unmanaged switching products, without
sacrificing the advanced functionality normally found
on higher-end managed switching products.
KEY BENEFITS
LAYER 2 SWITCHING WITH ADVANCED FEATURES
The Baseline Plus Switch 2900 Gigabit Family helps
build a voice ready network—with 3Com’s unique
auto-voice VLAN, advanced voice QoS, SNMP-based
management, Power over Ethernet (PoE) and other
features.
To ensure optimal use of the network bandwidth and
deliver maximum voice and data quality, traffic flow
can be directed according to the needs of the business
using Spanning Tree and Rapid Spanning Tree, traffic
prioritization, priority queuing and VLANs.
Link aggregation can be done via IEEE 802.3ad LACP
or manually, allowing ports to be grouped together to
form an ultra-high-bandwidth connection that greatly
expands bandwidth capacity to the network core or
other parts of the network.
Baseline Plus Switch 2900 models are available with
20, 28, and 52 ports; two 28 port PoE models (one with
170W budget and the other with 365W power budget)
deliver data and power over the same cabling. Each
switch also has four dedicated SFP ports for fiber
uplinks over longer distances.
ENTERPRISE-QUALITY SECURITY
Enterprise-quality security is provided with IEEE
802.1X network login and advanced Access Control
Lists (ACLs), which enable usage policies via the
switch at each point of access to the network. Time
based policies can also be configured on these
switches. All management communications are
encrypted with HTTPS.
POWER OVER ETHERNET
The Baseline Plus Switch 2928 PWR and 2928 HPWR
provides 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. These switches also support
pre-std PoE plus functionality that will enable the switch
to deliver 30W of power on each port.
NO SWITCH SETUP REQUIRED
Baseline Plus Gigabit 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 switch can be configured using a web
browser, console port, or SNMP management software.
ENHANCED INTUITIVE MANAGEMENT OPTIONS
For networks that require more control, the switch
web management interface provides an intuitive,
menu-driven process for even novice users to quickly
