Power saving with a Proliant server

We are going through a stage of power cost review and have decided to turn a number of servers off automatically overnight.
One such server is a HP ML350 G4P which is running Linux.  We power it off using a script.

Is there anyway we can get the server to turn itself back on at a specific time in the morning to save someone having to go and press the switch?

Thanks

Hello sheepfarmer,

Either use Power on LAN or turn it on with its inbuilt iLO card?

Can either method be automated (internally or from another machine)?

Also, how does Power on LAN actually work?

Thanks

WOL can be automated from a script on another machine http://www.depicus.com/wake-on-lan/wake-on-lan-cmd.aspx

Thanks PeteLong - All working now using WOL.

One interesting thing I found out was that the default installation of Fedora (Core 4 in my case) it not configured for WOL, which means when do you a shutdown -h now, the LAN card is actually turned off and not left in a state to accept future WOL magic packets.

The fix was to add
ETHTOOL_OPTS="wol g"

to
/etc/sysconfig/network-scripts/ifcfg-eth0

Thanks a lot for the info.
