Avaya Energy Saver - Avaya 3500 Series Getting Started

Getting started fundamentals
Important:
In order for AAUR to function properly, the new unit must be running release 5.1 software (or
later).

Avaya Energy Saver

You can use Avaya Energy Saver (AES) to reduce network infrastructure power consumption
without impacting network connectivity. AES uses intelligent switching capacity reduction in off-peak
mode to reduce direct power consumption by up to 40%. AES can also use Power over Ethernet
(PoE) port power priority levels to shut down low priority PoE ports and provide more power savings.
The power consumption savings of each switch is determined by the number of ports with AES
enabled and by the power consumption of PoE ports that are powered off. If AES for a port is set to
disabled, the port is not powered off, irrespective of the PoE configuration. AES turns off the power
to a port only when PoE is enabled globally, the port AES is enabled, and the PoE priority for the
port is configured to low.
You can schedule AES to enter lower power states during multiple specific time periods. These time
periods (a maximum of 42) can be as short as one minute, or last a complete week, complete
weekend, or individual days.
Important:
If a switch is reset while energy-saver is activated, the PoE power saving calculation might not
accurately reflect the power saving, and in some cases might display zero savings. This is
because the switch did not have sufficient time to record PoE usage between the reset of the
switch and energy-saver being reactivated. When energy saver is next activated, the PoE power
saving calculation is correctly updated.
When AES is active and you replace a unit, that unit will not be in energy save mode. At the
next deactivate/activate cycle, the unit will be in the correct state. You can issue the energy-
saver deactivate and activate command directly after replacing a unit to place the unit into the
appropriate energy savings mode.
