Static-Sensitive Devices
CAUTION:
Electrostatic discharge (ESD) can damage electronic components.To prevent damage to any
printed circuit boards, it is important to handle them very carefully. The following measures are
generally sufficient to protect your equipment from ESD damage.
■
Be sure that the appliance chassis is properly grounded through the AC power cord or enclosure
frame.
■
Touch a grounded metal object before removing the power supply from the anti-static bag.
■
Put on the grounding wrist strap, handle the power supply by its edges only, and do not touch
components on the bottom.
Single Power Supply Replacement
1. Ensure that the power cord is unplugged from the failed power supply module. Then, while
holding onto the handle, press the green locking tab on the bottom right of the power supply
in toward the handle.This will disengage the power supply.
2. Pull the power supply module straight out. Check to make sure that the replacement power
supply module is the same type as the one previously removed.
