Installation fundamentals

External power source only option

This module describes the external power source only option.

Using the Avaya Ethernet Routing Switch 5520-PWR switch and its external power source the

only option (Avaya Ethernet Redundant Power Supply Unit 15) you have is a total of 320 watts

of available power. You can power up to 48 ports at 6.6 W for each port with this configuration or

20 ports at the maximum power of 15.4 W for each port.

Power sharing option

This module describes the power sharing option.

Using the Avaya Ethernet Routing Switch 5520-PWR switch and the Avayal Ethernet 15 RPSU

as an external power source with the power sharing configuration supplies 740W to the Avaya

Ethernet Routing Switch 5520-PWR. This enables all 48 ports to supply the Max power of

15.4W for each port.

Power supply unit (PSU) option

This module describes the power supply unit option.

An external power source (Avaya Redundant Power Supply 15 (Avaya RPS 15)) can provide

redundant power to the Avaya Ethernet Routing Switch 5520. That is, the power fails over to

the Avaya RPS 15 in case there is a problem with the switch's internal power.

If the Avaya Ethernet Routing Switch 5520 is supplying 320 watts of power to Powered Devices

and the supply to the internal power source is interrupted, the power to all powered devices is

uninterrupted due to failover to the Avaya RPS 15.

By using the Avaya RPS 15, you have a total of 320W of PoE redundant power, which enables

up to 48 ports to be powered at 6.6W.
