The Ethernet Routing Switch 4500
Series (ERS 4500) provides genuine
resilient Stacking, Layer 2 switching
and Layer 3 routing, and advanced
convergence features. This enables the
ERS 4500 Series to deliver the scal-
ability and resiliency required by today’s
application-driven Enterprise networks
while reducing total operational costs.
Indeed, ERS 4500 models are up to
40% more energy efficient than compet-
itive products, ensuring superior total
cost of ownership.

Convergence-ready
For Businesses looking to bring together
their major forms of communication —
data, voice and video — onto a single
infrastructure, the Ethernet Routing
Switch 4500 delivers the functionality
that makes converging these technolo-
gies simple.

Through support for standards-
based Power-over-Ethernet (IEEE
802.3af PoE), power can be delivered
to IP-based Phones, Wireless Access
Points, CCTV Cameras and other
powered devices. This eliminates the
need to have separate power supplies for
each unit, thereby reducing cabling and
management costs when there are adds,
moves or changes. Additionally, with
Nortel’s auto-discovery and configura-
tion capability (ADAC), the ERS 4500
based Power-over-Ethernet (IEEE
802.3af PoE), power can be delivered
to IP-based Phones, Wireless Access
Points, CCTV Cameras and other
