Features & Benefits

High-Performance, Secure Voice-Ready Gigabit Power over Ethernet Connectivity
The 3Com® Switch 4500G is a stackable 10/100/1000 Ethernet switch that provides secure, flexible LAN connectivity and advanced voice-optimized features such as auto-voice VLAN and QoS. Optional 10-Gigabit uplinks via local connection modules or XFP transceivers supply highest-speed connections to other similarly-equipped devices.

The Switch 4500G offers Layer 2 switching and dynamic Layer 3 IPv4/IPv6 routing, as well as robust security, Quality of Service (QoS) and management features to deliver intelligent edge connectivity for essential business applications. This switch offers stackable scalability with single IP address management. This makes the Switch 4500G ideal for medium businesses and small enterprises seeking to build a secure converged network.

This switch comes with a limited lifetime warranty. Also provided is Advance Hardware Replacement, with next business day shipment available in most regions.

Power over Ethernet
Power over Ethernet (PoE) provides electrical power and data connectivity over a single Ethernet cable—resulting in significant cost savings when deploying devices like IP phones, wireless access points and IP security cameras.

Advanced Security
Enterprise-class security features include IEEE 802.1X network login, SSH/SSL encrypted device login, Access Control Lists and RADIUS Authenticated Device Access (RADA), protecting mission-critical business applications.

Voice-Ready Networking
Minimize the cost and complexity associated with adding or moving IP telephones: the Switch 4500 detects the presence of IP phones and dynamically assigns switch ports to the voice VLAN, enabling automated configuration and prioritization of Voice over IP (VoIP) traffic.
