2.3 ERS 4000 Series

The Avaya Ethernet Routing Switch 4000 Series contains 4500 and 4800 series models and is designed
for enterprise wiring closets and other network edge deployments. This stackable chassis system
provides Layer 2 switching and dynamic Layer 3 routing, convergence features, high performance, and
secure and resilient Ethernet switching connectivity. The Avaya Ethernet Routing Switch 4500/4800
Series switch models support 10/100 and 10/100/1000 switching and routing, PoE, PoE+, and 10 GbE
uplink options.
The ERS4000 series models designated with ―PWR‖ provide IEEE 802.3af-compliant (PoE, 15.4W), while
models designated with ―PWR+‖ provide both 802.3af (PoE) or 802.3at-compliant (PoE+, 32W) power on
all ports, and are contained within a RED (PoE models) or ORANGE (PoE+ models) line surrounding the
PoE ports.
ERS4000 series PoE model switches support the following maximum power budget per switch:
Switch Model
4526T-PWR
4550T-PWR
4524GT-PWR
4548GT-PWR
4526GTX-PWR
4526T-PWR+
4550T-PWR+
4826GTS-PWR+
4850GTS-PWR+
Note: ERS4500 ―PWR‖ (PoE) models support a Redundant Power Supply 15 (RPS15) connection at the
rear for DC power redundancy, or, for power load sharing which provides additional PoE power if
required. Newer model ERS4500/4800 ―PWR+‖ (PoE+) models use separate pluggable power supply
modules at the rear and do not support RPS15 connection. 300W and 1000W removable power supply
modules are available for these models.
When you use ERS 4500 PWR and 4500/4800 PWR+ units, you can plug any powered device into a
compliant front-panel port and receive power in that port. All ERS 4000 series PoE switches support the
Avaya Energy Saver (AES) feature.
