consumption can be reduced since signal attenuation is proportional
to cable length. When power-savings mode is enabled, the switch
analyzes cable length to determine whether or not it can reduce the
signal amplitude used on a particular link.

OTE
:
Power savings can only be implemented on Gigabit Ethernet ports
when using twisted-pair cabling. Power-savings mode on a active link only
works when connection speed is 1 Gbps, and line length is less than 60
meters.

These parameters are displayed:
•
Port – Power saving mode only applies to the Gigabit Ethernet ports
using copper media.
•
Power Saving Status – Adjusts the power provided to ports based on
the length of the cable used to connect to other devices. Only sufficient
power is used to maintain connection requirements. (Default: Enabled
on Gigabit Ethernet RJ-45 ports)
