(JPF)
Force-Power-On Enable/
Disable
Jumper JPF allows you to enable or
disable the function of Force-
Power-On. If enabled, the power
will always stay on automatically.
If this function disabled, the user
needs to press the power button to
power on the system.
3rd Power Supply Alarm
Enable/Disable
The system can notify you in the
event of the 3rd power supply fail-
ure. Use this feature when three
power supply units are installed in the
chassis with one acting as a backup.
If you only have one or two power
supply units installed, you should dis-
able this (the default setting) with
JP13 to prevent false alarms. See
the table on right for pin definitions.
