Chapter 2      Preparing to Install the CDE465 
Site Requirements
  •
When unpacking a static-sensitive component from its shipping carton, do not remove the 
component from the antistatic packing material until you are ready to install the component in your 
system. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from 
your body.
  •
When transporting a sensitive component, first place it in an antistatic container or packaging.
  •
Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and 
workbench pads.
Caution
For safety, periodically check the resistance value of the antistatic strap. The measurement should be 
between 1 and 10 megohms (Mohm).
