70-1 config power_saving mode
Description
This command is used to set the power saving state.
For link detection and length detection function, they apply to the ports with copper media. If the power
saving length detection function is enabled, the power is saved by the following mechanism:
5. When a link is detected on the port, for a shorter cable, the power consumption will
be reduced by lowering the signal amplitude, since the signal attenuation is
proportional to the cable length. The port will adjust the power based on the cable
length and still maintain error free applications from both sides of the link. This
mechanism is only available using the hardware support cable diagnostics function.
If the power saving state of port is disabled, all power saving schedules of port will not take effect.
If the power saving state of port LED is disabled, all power saving schedules of port LED will not take
effect.
If the power saving state of system hibernation is disabled, all power saving schedules of system
hibernation will not take effect.
