6.6
AC Inlet Connector
The AC input connector shall be an IEC 320 C-14 power inlet. This inlet is rated for 15A /
250VAC.
6.7
Marking and Identification
The power supply module marking supports the following requirements, safety agency
requirements, government requirements (if required, e.g. point of manufacturing), power supply
vendor requirements, and Intel manufacturing and field support requirements.
6.8
AC Input Voltage
The power supply operates within all specified limits over the following input voltage range,
shown in below table. Harmonic distortion of up to 10% THD must not cause the power supply
to go out of specified limits. The power supply shall power off if the AC input is less than
75VAC +/-5VAC range. The power supply shall start up if the AC input is greater than 85VAC
+/-4VAC. Application of an input voltage below 85VAC shall not cause damage to the power
supply, including a fuse blow.

AC Line Transient Specification
AC line transient conditions are defined as "sag" and "surge" conditions. "Sag" conditions are
also commonly referred to as "brownout", these conditions will be defined as the AC line voltage
dropping below nominal voltage conditions. "Surge" is defined to refer to conditions when the
AC line voltage rises above nominal voltage.
The power supply meets the requirements under the following AC line sag and surge conditions.
