Power Supply And Input Power Requirements; Motherboard Jumpers - HPE AlphaServer 300 User Manual

Power Supply and Input Power Requirements

Your system comes with a 180-watt or a 210-watt power supply; either of these power
supplies fully meets your system's requirements. Both provide five DC voltages: +12 volt,
-12 volt, +5 volt, -5 volt, and +3.3 volt DC. These voltages are used by the various
components within the system. Table A-5 lists the input power requirements.

Rated Voltage Range
100 volt AC – 120 volt AC
220 volt AC– 240 volt AC
¹ Includes outlet current.

Motherboard Jumpers

Jumper pins allow you to set specific system parameters. Do this by changing the pin
location of jumpers (the small, plastic-encased shorting plug that slips over the pins). To
change a jumper setting, use your fingers or a pair of needle-nose pliers to remove the
jumper from its current location. Place the jumper over the two pins designated for the
desired setting. Press the jumper evenly onto the pins. Be careful not to bend the pins.
Jumpers J2, J3, and J27 may be of interest to the user; all others should remain at factory
default. Figure A-1 shows the locations of the motherboard jumper pins. Table A-6 lists
the motherboard jumpers and factory-default settings. Notice that the square pin of each
jumper block is pin 1.
________________________ CAUTION ___________________________
Do not touch any electronic component unless you are safely grounded. Wear a
grounded wrist strap or touch an exposed metal part of the system unit chassis.
A static discharge from your fingers can permanently damage electronic
components.
