NEC 140Rc-4 manual Degradation Feature, Remote Power-On Feature Wake On LAN, AC-LINK Feature

General Description 2-21

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)

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 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: Wake On LAN feature is supported in 100BASE-TX adapter on the baseboard. It is also supported in PCI slot #1 and #2 if the adapter which applies to Wake On LAN is installed.

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.)
