Configuring the Deep Power Saving Mode
Context
The device enters the sleeping
mode when the following conditions are met:
- The device works in deep mode. By default, the standard energy-saving mode is used.
- A time range applies to the device in sleeping mode.
- During the period for continuously detecting awakening port status,
the terminals (switches or PCs) connected to awakening ports are shut
down.
If the terminal is a PC, the device can enter the dormancy state only when the PC is shut down and its network adapter is powered off (this can be set in the power management module of BIOS).
The device is awakened when either of the following
conditions is met:
- A user logs in to the device through the serial port and presses Ctrl+W.
- The terminals (switches or PCs) connected to awakening ports are started up.
