This section provides information on the test results for the compatibility of NSP Pro and UPS service software with Windows 2000.
The test results manifest whether or not the software can remotely control the functions of nonstop power supply from a Windows 2000 personal computer. 

Functional verification test result for NSP Pro (software for Windows NT 3.51/4.0)

The NSP Pro executed the shutdown control sequence from the power outage detection to OS shutdown, except for the "power supply shutdown" at the final step. The power supply stayed in the standby mode of operation without proceeding to complete shutdown (turning off all the outputs).

Note: It seems that the API could not function after OS shutdown in Windows 2000 whereas it could be effective in Windows NT4.0 environment.

ACPI (or APM) of Windows 2000 automatically makes the power supply stop its DC outputs after the OS ends. The problem arises in the next step. While the NSP Pro (running on Windows NT 3.5/4.0) transmits a shutdown signal to the power supply as Restart (Reboot) button is displayed, this function doesn't work on Windows 2000 system. As a result, +5 VSB (standby voltage) remains being outputted after the OS shutdown, though all the DC outputs (except for +5 VSB) are stopped.  

Note: The 5 VSB problem arises because Windows 2000 system performs only the Remote ON/OFF control using an output signal at pin 14 of 20-pin main connector. The shutdown control signal to make the power supply turn off is not used. Since the +5 VSB remains being outputted, backup battery continues to discharge until it ends unless the power supply is completely shut down otherwise.

Note: This problem depends on the model number of the power supply. The NSP3-150-D2S shuts down completely when Remote OFF control is performed in battery backup mode of operation. Therefore, the NSP3-150-D2S can be used in the Windows 2000 system environment.

Functional verification test result for UPS Control service of Windows 2000

Windows 2000 provides UPS control service which has more extensive functions than that of Windows NT 4.0. While the UPS control service of Windows NT 4.0 is supported with a "UPS" icon on Windows main screen, that of Windows 2000 is available from "Power Supply Option" icon on Windows main screen. 

Test result for the power monitoring and shutdown control operation using the UPS Control service function was the same as that of NSP Pro.

Initial setups and test conditions

Perform the following initial setups to start up the UPS control service function.

 

 

Click "Power supply option" icon to open the property.
Click "UPS" tag to open UPS status display page as shown below.
Click "Select" button to open UPS selection menu.

 "None" is initially selected and displayed in the UPS supplier list box. 
Click pull-down menu key to view the supplier list. 
Windows 2000 Professional RC2 displays only American Power Conversion in the supplier list. 
Select "Generic" to perform the setup for NSP series power supplies. 

Select "Custom" from the list in "Select Model" list box.
UPS Interface Configuration dialog box will be displayed. (See figure below.) 
Select the polarity of UPS signals as follows:
(1) Check off Power interruption/Battery backup. Click "Negative" option button to set the polarity of this signal to Negative.
(2) Remove check from Battery Low. (or set the polarity to Negative.)
(3) Check off UPS Shutdown. Click "Positive" option button to set the polarity of this signal to Positive.
Confirm that all the polarities of UPS signals are correctly set as shown below: 
 

After all the setups are finished, close the property of Power Supply Option.
The UPS control service function will be initiated.

Besides, alarm display time on the occasion of power outage, a program to run automatically and affirmation/denial for UPS shutdown can be set up by using "Configuration of UPS" dialog box on the Details setup display window. For the functional verification test, the configuration of UPS was defined as shown in the above figure.


Test result:

The functional verification test lets the personal computer perform the power monitoring and shutdown control operation using the UPS Control service function after a nonstop power supply is connected to the PC system.
The test result was as follows:

The UPS Control service function executed the shutdown control sequence from the power outage detection to OS shutdown, except for "power supply shutdown" at the final step. 
Like the NSP Pro for Windows NT, the power supply stayed in the standby mode of operation without proceeding to complete shutdown (turning off all the outputs).
