OVERVIEW

The “smart” voice-ready 3Com®Baseline Switch 2900 Plus Family
delivers Layer 2 enterprise-class Gigabit switching solutions, 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 Switch 2900 Plus helps build a voice ready network—
with 3Com’s unique auto-voice VLAN, advanced voice QoS, SNMP­based 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 Switch 2900 models are available with 16, 24 and 48 ports; a
24-port PoE version delivers data and power over the same cabling. Each
switch also has four dual-purpose ports (configurable as 10/100/1000
copper or SFP-based fiber) to connect to high-performance computers,
servers, or network backbones.

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. All management
communications are encrypted with HTTPS.

POWER OVER ETHERNET

The Baseline Switch 2924-PWR Plus 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.

KEY BENEFITS

(CONTINUED)

NO SWITCH SETUP REQUIRED

Baseline Plus switches are operational straight out-of-the-box; as long as default settings are acceptable, there
i

s 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

F

or networks that require more control, the switch web management interface provides an intuitive, menu­driven process for even novice users to quickly and confidently configure the switch during initial setup
and manage it during normal operation. Graphical switch and port views provide a clear understanding of
s

witch status and configuration.

In addition, the web interface features individual port-traffic monitoring (port mirroring) and MAC address
port mapping tables. A cable diagnostic tool lets users troubleshoot basic connectivity problems via the web
management interface further simplifying network installation.

The Baseline Switch 2900 family is also supported by 3Com Network Supervisor (3NS) and 3Com Network
Director (3ND) management software. 3NS and 3ND can be used to map the network topology, indicating
what devices are connected, and on what ports. Switch management and software upgrades can be easily
done. Other SNMP-based management tools may also be used.

The Switch family also supports a compact Command Line Interface (CLI) that is accessed via the front panel
console port. Using the CLI, major switch management options can be quickly configured.

Feature Description

Performance

VLANs Segment the network by grouping users based on their data or traffic exchange requirements. This ensures

optimal use of available bandwidth as traffic flow is directed according to the needs of the business.

Advanced QoS and traffic shaping Traffic prioritization, using IEEE 802.1p Quality of Service (QoS) and Type of Service (TOS) with Differentiated

Services Code Point (DSCP), and ingress/egress rate shaping help ensure that critical time-sensitive traffic
like voice gets the priority needed for quality communications.

Link aggregation (trunking) Group together any number of ports automatically using Link Aggregation Control Protocol (LACP), or manually,

to form an ultra-high-bandwidth connection to the network backbone; help prevent traffic bottlenecks.

Rapid Spanning Tree Protocol support Improves network compatibility, scalability and availability.

IGMP snooping Multicast filtering optimizes network performance, instead of flooding traffic to all ports.

Unique voice features Automatic assignment of voice traffic to separate VLANs (“auto-voice VLAN”), advanced voice QoS, traffic shaping,

multicast filtering and PoE support delivers the support necessary for quality voice communications.

Flexible Gigabit uplinks Daisychain multiple units together via the built-in copper Gigabit uplink ports or connect to a network backbone

via SFP-based fiber modules.

PoE support (PWR model only) Provides power for IP phones, wireless LAN access points, and other IEEE 802.3af-compliant devices over the

same cable used for data; lowers total cost of ownership since there is no need to run additional electrical wiring.

Security

IEEE 802.1X network access control Provides standards-based security combined with local authentication.

Advanced Access Control Lists (ACLs) MAC- and IP-based ACLs enable network traffic filtering and enhance network control.

Traffic monitoring (port mirroring) Administrators can examine suspect data streams received on any port by mirroring the data stream to a

monitoring port.

Configuration and management

Enhanced browser-based interface Graphical user interface allows even the most novice users to configure the switch during initial setup and

monitor it during normal operation.

SNMP support Switch can be managed with 3Com Network Supervisor, Network Director and other SNMP-compatible tools.

PoE configuration PoE power can be enabled or disabled per unit and per port; power can also be limited per port.

Cable diagnostics Remotely detect copper cable issues using a browser-based tool.
