Wake on LAN from S5

Posted on 2014-02-19

In the BIOS of an NEC server - we have under the power setting, the option to "wake on LAN from S5" which is set to power on.

We wish to minimize the power consumption and have the server switch to a low power mode when not being utilized (which mostly happens often).

Being a file server which is occasionally used from time to time.

How does the "wake on LAN from S5 take its input? Is it from the LAN?

With the setting on - will it wake up the server when we do a file request?

S5 is fully off state, not hibernation or sleep.  This means it is powered down or turned off.   See

From the network.

A special packet - the term magic packet is used - needs to be sent to the computer to wake it up and boot.  See for the details.
