■
Power saving when there is a link partner:
Traditional Ethernet connections typically operate with enough
power to support at least 100 meters of cable even though average
network cable length is shorter. When cable length is shorter, power
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.
N 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.
PARAMETERS
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)
