Redundant power supply

The Avaya Ethernet Routing Switch 4500 Series Power over Ethernet (PoE) switches, Avaya
Ethernet Routing Switch 4548GT-PWR, and Avaya Ethernet Routing Switch 4550T-PWR, can
use an optional 470-Watt (W) Avaya Ethernet Routing Switch RPS 15 redundant power supply.
The RPS 15 power supply chassis is two units high and can accommodate up to three RPS
modules, each supporting up to four devices, to provide redundant power and uninterrupted
operation in power failure. One RPS module connected to a PoE switch can provide up to 15.4
W for each port on all 48 ports. The RPS modules fit into the rear of the RPS 15 chassis. The
UPS and associated battery pack module fit into the front of the chassis.
The non-PoE switches, Avaya Ethernet Routing Switch 4548GT, 4550T, and 4526FX, can use
an optional 150W Avaya Ethernet Switch Power Supply Unit 10 and require the DC-DC
Converter Module. The Avaya Ethernet Switch Power Supply Unit 10 provides scalable power
redundancy and protection to low-wattage networking equipment. The PSU modules slide into
the front of the Avaya Ethernet Routing Switch RPS 15 chassis.
