System Overview 1-21
Online Spare Memory
Online spare memory is a new high-availability feature on your server.
Online spare memory allows the server to continue operation should a DIMM begin to fail. When a
pre-defined threshold for the maximum number of correctable ECC errors has been exceeded,
online spare memory initializes the bank in standby (spare bank) and takes over the failing memory
bank.
The memory bank that exceeds the error threshold can be replaced at the customer's convenience
during a scheduled shut down.
With online spare memory, degraded memory is automatically disengaged and a fresh set of
memory is used in its place. This brings the reliability of the system to the pre-failure level without
any service interruption and without compromising system availability.
Remote Power-On Feature
(Wake On LAN)
The remote power-on function turns on the server through a network. It sends a special packet
from the management computer to a remote server to turn it on if the server is off-powered.
To enable this feature, you must select "Enabled" for "Wake On LAN" in the Advanced Chipset
Control of the Advanced menu of the BIOS setup utility, "SETUP." (See Chapter 3)
The remote power-on feature is not available in the following cases. Press the POWER switch
once to start the OS, and turn off the server in an appropriate procedure.

Abnormal previous system shut-down
!
No power supply to the server (due to turned-off breaker, disconnected power cord, power
blackout, etc.)
AC-LINK Feature
When the power cord of the server is connected to an uninterruptible power supply (UPS) unit, the
server supports the power linkage feature that enables control over the power supply from the UPS
to the server. The AC-LINK feature can be enabled or disabled with the Server menu of the BIOS
setup utility, "SETUP." (See Chapter 3)
