Degradation Feature - NEC N8100-1220F User Manual

2-22 General Description

Degradation Feature

The degradation feature automatically isolates a failed DIMM, processor, or cooling fans to assure
continuous operation of the server when the POST (Power On Self-Test, self-diagnosis program
after power on) detects such a DIMM, processor, or cooling fans.
Failed DIMMs, processors, and cooling fan may be identified on the screen that the POST displays,
or with the BIOS setup utility, "SETUP." They may also be identified on the system that has the
NEC ESMPRO installed.
Remote Power-On Feature (Wake On LAN/PME)
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/PME" in the Advanced
Chipset Control of the Advanced menu of 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.)
NOTE:
TX/1000BASE-T adapter on the I/O board.
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. AC-LINK feature can be enabled or disabled with "AC-LINK" in the Server menu
of the BIOS setup utility, "SETUP." (See Chapter 4.)
Wake On LAN feature is supported in 100BASE-
