Network-Level Availability
XRN (eXpandable Resilient Networking)
technology is a 3Com innovation that enables
multiple interconnected and stackable Layer 3
switches to behave as a single management
entity.

Automated stack and fabric setup delivers
high resiliency and continuous availability
without adding to network complexity.
Once configured, all switches actively share
network loads and routing intelligence and
support ultra-fast failover recovery for lost
or disconnected switches.

Multilayered Security
These advanced enterprise switches integrate
distributed security enforcement and
centralized network management features.
Access Control Lists (ACLs) help safeguard
access to key network resources from
unauthorized access and data corruption.
User-based authentication and DES 56-bit
encryption help secure Layer 3 protocols and
management controls, such as SSH and SNMP.
IEEE 802.1X RADIUS Network Login and
RADIUS Authenticated Device Access (RADA)
enforce access control at the network’s edge.

Priority for Converged and
Business-Critical Traffic
Next-generation features—advanced,
policy-based Class of Service/Quality of
Service (CoS/QoS), eight priority queues,
committed access rates, bandwidth limiting
and filtering, and more—identify and
prioritize time-sensitive traffic, including
voice over IP (VoIP). For assured privacy,
switches can be configured to isolate 3Com

Unique AC-/DC-Powered Operation
Support for AC- and direct DC-powered
operation leverages your existing power
schemes in data centers and switching
infrastructures. The state-of-the-art
Redundant Power System (RPS) is
designed to work with the 3Com Switch
5500. This RPS can provide supplemental
N+1 power across all PoE ports in the
switch, provisioning up to 384 ports with
a full 15.4W.

Powerful, Unified Management
Switches are powered by the 3Com Operating
System, the same proven software shared
across our premium enterprise products
including the 3Com Switch 8800 and 7700
modular families. This consolidates
administrative control over the entire
switching infrastructure when using 3Com
management application software such as
3Com Enterprise Management Suite and
3Com Network Director.
