3. Do not set the "Low Charge Shutdown Threshold" too low! The remaining
battery charge should be set to a level that will allow the UPS to support the
PC for the duration of the "Windows Shutdown Delay" plus the actual time it
will take your PC to shut down. Take into consideration that if the "Empty
Batt Level" setting of the UPS is other than zero, it will further reduces the
UPS holdup time.
4. For reliable operation it is advisable to leave at least a 25% of the
battery charge as a “safety margin” (to account for battery aging,
inaccuracy of the battery monitor, etc.)
3.4.3. "Run Custom Shutdown Program" – Checking this box and specifying the
full path to the program in the "Program Location" field (you may use the
"Browse..." button to select the program), will cause the Application to
execute a user’s program when the Shutdown Procedure is triggered.
Notes:
1. The Custom Program will be executed under SYSTEM user, meaning it has
very high privileges.
2. On Windows 7 and Windows 2008 - The Custom Program will be executed in
Session 0 so it can't directly interact with the user.
3.4.4. "Shutdown Window" – Checking this box will cause the Application
(when the Shutdown Procedure is triggered) to initiate a delayed Windows
Shutdown. The delay between the triggering of the Shutdown Procedure, to
Windows shutdown is specified in the "Windows Shutdown Delay" field.
During this delay a shutdown dialog box will be displayed, warning the user
to save their work. If you do not want the Application to shutdown
Windows, uncheck the "Shutdown Windows" checkbox.
3.4.5. "Shutdown UPS" – Checking this box will cause the Application (when the
Shutdown Procedure is triggered) to initiate a delayed UPS Shutdown. The
delay between the triggering of the Shutdown Procedure, to the UPS
shutdown is specified in the "UPS Shutdown Delay" field. If the PC is fed by
the UPS, the "UPS Shutdown Delay" should be set such that it will be longer
than the "Windows Shutdown Time" plus the time that it takes the PC to
actually shutdown. If you do not want the Shutdown Procedure to
shutdown the UPS, uncheck the "Shutdown UPS" checkbox.
Note:
If you check the “Shutdown the UPS” box, the SNMP User Name that you have
entered must have a “Write Permission”. If the SNMP User Name has a “Read Only”
permission, it won't be able to shutdown the UPS.
