Server Technology PP02 - Manual (Page 47)

Appendix C - Windows NT/2000/XP ShutDown
Introduction
Windows NT, Windows 2000 and Windows XP must be shut down prior to turning off power. When a user is at the
computer, the user can perform the necessary shutdown manually. With Remote Power On/Off, the user is not at the
computer, and consequently may not be able to perform the necessary shutdown prior to the power being turned off.
To solve this problem, Server Technology introduced the Power On/Off +Aux S HUT D OWN / RE BOOT for Windows NT,
model #PPNT. This version contains modified firmware, an IPM/ShutDown signal Y-cable, and a serial port adapter.
Working with the UPS Service that exists in Windows NT/XP/2000, these items allow Remote Power On/Off to signal
Windows to shut down prior to turning power off. The Y-cable connects the Remote Power On/Off to the IPM and also
to a serial port on the Windows NT/2000/XP system. The UPS Service for Windows then monitors the serial port for the
signal from the Remote Power On/Off to shutdown the operating system. The Power On/Off +Aux ShutDown/
RE BOOT
unit will signal a shutdown to occur 3 minutes and 30 seconds before power is turned off or a RE BOOT cycle is started.
This appendix describes the cabling, the functional changes to the Remote Power On/Off, the configuration of the UPS
Service built into Windows NT 3.51+, and also the configuration of the newer UPS Service specific to Windows 2000
and XP. Also, this appendix identifies how to obtain information from Microsoft for enabling the AutoAdminLogon
feature of Windows NT in order to bypass the <Ctrl><Alt><Del> key sequence that is normally required to log on.
IPM/ShutDown Signal Y-cable
A custom Y-cable accompanies the Windows NT/2000/XP ShutDown version of the Power On/Off +Aux. This cable
replaces the "IPM Signal Cable" described on page 10 and shown on page 14.
This Y-cable serves two purposes - 1), to signal the IPM to turn power on or off, and 2) to signal the UPS Service of
Windows NT/2000/XP to shut down the operating system. The cable has a Y-configuration, meaning one end of the
cable splits off to two other ends, like the lines of the letter "Y". This Y-cable connects to the back of the Power On/Off
+Aux unit into the IPM Port, and then splits off with one end going to the Intelligent Power Module and the other end
going to the ShutDown adapter attached to a serial port on the Windows system.
Because it is very important that the correct ends of the Y-cable go to the IPM and to the ShutDown adapter, the Y-cable
is color keyed on the two individual ends. The blue end connects into the side of the IPM, while the red end connects
into the serial port ShutDown adapter.
