2.1.1.2 Handle Retention
The power supply has a handle to assist extraction. The module is able to be inserted and
extracted without the assistance of tools. The power supply has a latch which retains the power
supply into the system and prevents the power supply from being inserted or extracted from the
system when the AC power cord is pulled into the power supply.
The handle protects the operator from any burn hazard.
2.1.1.3 LED Marking and Identification
The power supply uses a bi-color LED: Amber and Green. Below are table showing the LED
states for each power supply operating state and the LED’s wavelength characteristics. Refer to
the Intel
®
LED Wavelength and Intensity Specification for more details.
