SWITCHI G
DATA SHEET
OVERVIEW
The 3Com®OfficeConnect®Managed Gigabit Switch
delivers Layer 2 enterprise-class Gigabit switching
solutions, customized and priced for small and mid-
sized organizations, in a compact and quiet desktop
enclosure.
This managed switch offers 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 OfficeConnect Managed Gigabit Switch helps build
a voice ready network—with advanced voice QoS,
S MP-based management, Radius authentication and
other features.
This switch has seven 10/100/1000 ports, and a dual-
purpose Gigabit port (configurable as 10/100/1000
copper or SFP-based fiber) to connect to high-
performance computers, servers, or network
backbones.
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 VLA s.
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.
ENTERPRISE-QUALITY SECURITY
Enterprise-quality security is provided with IEEE
802.1X network login, which enable usage policies via
the switch at each point of access to the network.
NO SWITCH SETUP REQUIRED
The OfficeConnect Managed Gigabit Switch is
operational straight out-of-the-box; as long as default
settings are acceptable, there is no need to configure
it. If desired, the switch can be configured using a web
browser, console port, or S MP 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
and confidently configure the switch during initial
setup and manage it during normal operation.
In addition, the web interface features individual port-
traffic monitoring (port mirroring) and MAC address
tables. A cable diagnostic tool lets users troubleshoot
basic connectivity problems via the web management
interface further simplifying network installation.

FEATURE HIGHLIGHTS
FEATURE DESCRIPTION
Performance
VLA s 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), 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.
Flexible Gigabit uplink Daisychain multiple units together via the built-in copper Gigabit uplink port or connect
to a network backbone via SFP-based fiber modules.
Fanless design Silent operation whether used in a rack or desktop situation.
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.
Confi uration and mana ement
Enhanced browser-based interface User interface allows even the most novice users to configure the switch during initial
setup and monitor it during normal operation.
S MP support Switch can be managed with S MP-compatible tools.
Cable diagnostics Remotely detect copper cable issues using a browser-based tool.
