Using the Remote
Power-On Pins
The remote power-on pins (pins 5 and 18) of the Diagnostic Connector allow
you to turn the mainframe on and off without using the front panel On/Stdby
switch. With the On/Stdby switch in the Stdby (off) position, connecting pin
5 to pin 18 on the diagnostic connector turns the mainframe on.
Disconnecting pin 5 from pin 18 turns the mainframe off.
Note
Pin 18 is ground in the HP E8402 and E8404 mainframes. Therefore,
you only need to ground pin 5 to turn the mainframe on.
