Scalability
Enhanced Layer 2 10/100/1000 LAN
switching solution delivers scalable
wirespeed Gigabit performance, with
integrated stacking up to eight units high,
or 384 Gigabit ports, with high-bandwidth
40Gbps stacking. Stack-wide link
aggregation enables high-performance
connectivity to the core of the network,
with up to eight ports from different units
aggregated together to improve resiliency
and uptime.

Performance
24 or 48 built-in copper Gigabit ports,
including four dual-purpose ports
supporting copper links or SFP adapters
for easy, flexible connection to fiber-based
Gigabit media.

Port-based rate-limiting enables the
bandwidth on each port to be restricted, so
power users can receive the full bandwidth
available while non-key users can be
throttled down, preserving network
bandwidth and allowing maximum control
of network resources. Built-in packet
prioritization gives optimal performance
to real-time applications such as voice and
video.

Future Protection
Gigabit to the desk prepares your network
for the future at prices comparable to those
of some 10/100 switches. Tri-speed operation
at 10-, 100-, and 1000Mbps allows easy
migration to Gigabit speeds.

Investment protection is further enhanced
with switching silicon designed to support
multilayer switching, and a module slot
that supports a single-port 10Gigabit
Ethernet module, with CX-4, LR, or ER
XENPAK ports that can be used to connect
back to the network core.

Ease of Use
Automatic selection of the optimal speed
and duplex mode of cables connected to it
prevent mis-configuration of the network.
The switches also detect and adjust to
cross-over or straight-through cable
connections—a feature called auto
MDI/MDIX—eliminating the need for
specific cables.

Security
IEEE 802.1X network login helps enable
intrusion prevention on the network,
requiring users to authenticate with a
central standards-based RADIUS server for
ease of management; unauthorized users
are kept off the network.

Management of the switch can be
implemented using Secure Shell (SSH)
and Secure Sockets Layer (SSL / HTTPS)
encryption, preventing unauthorized
remote access to the switch over IP
networks or from a web browser.

Powerful Management
Comprehensive support within the 3Com
management application software suite,
including the standalone package 3Com
Network Director or 3Com Network
Administrator for HP OpenView-based
management. 3Com Network Supervisor
may also be used in smaller networks.
