5.5.4 Notes on Advanced Uninterruptible Power Supply
(UPS)
Note the following points when using an advanced uninterruptible power supply (referred to as UPS
afterward).
■ UPS Shutdown Time Setting
Specify enough time for the UPS power-off time (time from the shutdown direction to the actual power-
off). If this time is set insufficiently, the power will be cut off before system shutdown, which may result
in destruction of data. For more details, refer to the manuals for UPS and UPS management software.
■ Power Supply Control by UPS
Change BIOS settings as follows to power the server on automatically using the UPS management
software (PowerChute Network Shutdown, PowerChute Business Editon) at power recovery or during
scheduled operation. For details on how to set the BIOS Setup Utility, refer to "8.2 BIOS Setup Utility"
(
pg.223).
1 Start the BIOS Setup Utility.
2 From the [Advanced] menu, select the [Power On/Off] submenu and press the
[Enter] key.
The [Power On/Off] submenu window appears.
3 Set the [Power Failure Recovery] to [Always On].

5.5.5 Turning the Power On via a LAN
You can turn the power on the server from a client (via a LAN) by utilizing the Wakeup on LAN (WOL)
function.
Be sure to install ServerView to control the power supply via a LAN.
When the power cable is disconnected from the server or the server is powered off due to power
interruption, restart the server. Unless the server is restarted, the WOL function will be disabled.
