Configuring the Deep Power Saving Mode

Configuring the Deep Power Saving Mode


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.
  • The sleeping time range expires (if a time range is configured).
  • A user presses the mode switching button.

The S5700S-28P-LI-AC and S5700S-52P-LI-AC in the S5700S-LI series and S5700-28P-LI-AC, S5700-28P-LI-DC, S5700-52P-LI-AC, S5700-52P-LI-DC in the S5700LI series restart before they enter the sleeping mode. After the switches awake, unsaved configurations are lost, and the configurations that require a restart to take effect automatically take effect. Save configurations before a switch enters the sleeping mode.

After a switch enters the sleeping mode, you can log in to the switch through its serial port and press Ctrl+\ to check the remaining sleeping time.
