2.1 ERS 2500 Series

Avaya Ethernet Routing Switch 2500 series includes a range of energy-efficient, Fast Ethernet switches
suitable for branch office and entry-level enterprise wiring closet deployments. ERS 2500 Series switches
offer intelligent stacking, virtual hot swap for in-service maintenance and restoration, and include
automatic QoS, Power over Ethernet (PoE), simple IP Phone deployments, and a wide range of flexible
security options.
The ERS 2550T-PWR and 2526T-PWR provide IEEE 802.3af-compliant (PoE, 15.4W) power on half the
ports, and are contained with a RED line surrounding the ports supporting PoE. These switch models
provide power discovery, power management, and power use statistics per port and per switch and do
not support Avaya Energy Saver. ERS2500 PoE model switches only support PoE on the lower-
numbered ports, and provide a total PoE budget of 168W per switch.
The ERS 2500 switches optimize power consumption. You can configure each port to a power priority
level of low, high, or critical, limiting the amount of power delivered to non-business-critical devices.
