Attention:
Before the computer is powered on after FRU replace-
ment, make sure all screws, springs, and other small parts
are in place and are not loose inside the computer. Verify
this by shaking the computer gently and listening for rat-
tling sounds. Metallic parts or metal flakes can cause elec-
trical short circuits.
Attention:
The system board is sensitive, and can be damaged by
electrostatic discharge. Establish personal grounding by
touching a ground point with one hand before touching
these units.
You must use an electrostatic discharge (ESD) strap (P/N
6405959) to establish personal grounding.
