browser or SNMP management software, and is fully supported
when using 3Com Network Supervisor and Network Director.
Enhanced Browser-Based User Interface

Simplify Voice over IP (VoIP)
Automate configuration,
detect IP phones, dynamically assign switch ports to the Voice VLAN
and prioritize VoIP traffic using the unique Voice VLAN feature.
Effectively minimize the cost and complexity associated with adding
or moving IP phones.
Cost Effective
With PWR modules, delivering Power over Ethernet means electricity
and data are provided over a single Ethernet cable, resulting in significant
cost savings when deploying devices such as IP phones, wireless
access points and IP security cameras.
Scalable Switching Solution
Flexible in design, the switches have dual-personality Gigabit
Ethernet interfaces for copper or fiber connections. Manage clusters
of 3Com Enterprise switches together as a single entity with a single
IP address — Switch 4500 units together with other fully managed
3Com devices including Gigabit models.
