Nortel Ethernet Routing Switch 4548GT-PWR Specification Guide

Nortel Ethernet Routing Switch 4500 Series

The Nortel Ethernet Routing 
Switch 4500 Series is a Stackable 
system providing high-performance, 
convergence-ready, secure and resil-
ient Ethernet switching connectivity. 
Available as a range of 11 model variants 

supporting 10/100 and 10/100/1000 
switching, Power-over-Ethernet and 
10 Gigabit Ethernet uplink options, 
the Ethernet Routing Switch 4500 
Series is ideally suited for Enterprise 
wiring closet and other network edge 
deployments.

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.

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
