2-20 General Description
Degradation Feature
The degradation feature automatically isolates a failed DIMM or processor to assure continuous operation of the server when
the POST (Power On Self-Test, self-diagnosis program after power on) detects such a DIMM or processor.
NOTE:
The degradation feature is only available when at least two DIMMs or processors are
installed.
Failed DIMMs and processors may be identified on the screen that the POST displays, or with the BIOS setup utility of the
server, "SETUP." They may also be identified on the system that has the NEC ESMPRO installed.
Memory RAS Features
Your server board has the memory mirroring and LockStep features. For detail explanation, refer to Chapter 9.
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, use the BIOS setup utility, "SETUP." (See Chapter 4.)
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 4.)
