Current Usage

120
The rest of this chapter consists of worksheets to record the settings you make when
configuring the system using the SSU, BIOS Setup, and the Symbios SCSI Utility. If
default values ever need to be restored to CMOS (e.g., after a CMOS-clear), you must
reconfigure the system. Referring to the filled-in worksheets could make your task easier.
Circle or write in your selections or the values that are displayed onscreen.
As all SGI 1400 servers come equipped with three power supplies standard, power usage
is not generally a critical consideration. The system administrator or service person may
wish to calculate system power usage for other reasons.
As an overall current usage limitation on the power supply, do not exceed a combined
power output of 195 watts for the +5 and +3.3 volt outputs.

Calculating Power Usage

The total combined wattage for the system configuration must be less than 400 watts.
Use the two worksheets in this section to calculate the total used by your system. For
current and voltage requirements of add-in boards and peripherals, see your vendor
documents.
