AMP Sleep
APM (Advanced Power Management) is a standard in power management developed by Intel and Microsoft, which allows the operating system to control the amount of power sent to devices. Select EMAC products allow for APM Sleep, a command that puts the device into a lower power "deep sleep" state and minimizes the device's power consumption.
From the command line, use command:
sleep [N]..
where [N].. is time equal to the total of the args given, where each arg can
have an optional suffix of (s)econds, (m)inutes, (h)ours, or (d)ays
After the given time, the device will resume normal operation and power consumption.
