OVERVIEW
The 3Com
®
Switch 4500G Gigabit Family 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.

CONNECTIVITY
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.

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