3.1.6 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 also 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 through the use of industrial designed
plastic handle or equivalent material.
3.1.7 LED Marking and Identification
The power supply is using a bi-color LED: Amber and Green for status indication. Below are
table showing the LED states for each power supply operating state.
