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 a 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 may
not accurately reflect the power saving, and in some cases may 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 will be correctly updated.

¹The power consumption values in this table can vary by up to 10%. Power consumption
values can differ if a switch operates at different voltages. Power supplies operating at higher
voltages are generally more efficient.
