Switch 4500G 10/100/1000 Family

DATA SHEET

High-Performance,

Secure Voice-Ready

Gigabit Power over

Ethernet Connectivity,

Ideal for Medium

Businesses and Small

Enterprises

OVERVIEW

The 3Com ® Switch 4500G delivers flexible quad-speed performance–

10/100/1000 and 10-Gigabit–and advanced voice-optimized features such as Power over Ethernet (PoE) and auto-voice VLAN and QoS.

This makes the Switch 4500G ideal for medium businesses and small enterprises seeking to build a secure converged network.

KEY BENEFITS

MANAGED LAYER 2 AND LAYER 3 GIGABIT CONNECTIVITY

Wirespeed Layer 2 Gigabit switching with dynamic Layer 3 Gigabit routing make the Switch 4500G ideal for wiring closet, workgroup and small core connectivity requirements. In addition, four of the ports are dual-personality, operating either as 10/100/1000 or SFP-based fiber providing greater flexibility. These switches also accommodate up to four extra optional 10-Gigabit high-speed links, enabling connectivity to a core network or to high-performance servers.

SECURE

Enterprise-class security features include IEEE 802.1X network login,

SSH/SSL encrypted device login, and Access Control Lists, protecting mission-critical business applications.

VOICE-READY

Minimize the cost and complexity associated with adding or moving IP telephones: the Switch 4500G 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. Optional

PoE models provide electrical power and data connectivity over a single

Ethernet cable—resulting in significant cost savings when deploying these phones.

INVESTMENT PROTECTION

These switches come with a limited lifetime warranty covering the unit, power supply and fan. Also provided is Advanced Hardware

Replacement, with next business day shipment available in most regions.
