The metal sleeve must be removed for the following operations:
· Fitment of additional RAM cards
· Selection of communication standard for ports A, B and C.

Caution
The module contains static sensitive components and care must be
taken to ensure that the surface onto which the printed circuit board
assemblies are to be placed and the user are at the same potential.
Standard anti-static precautions should be observed.
If full anti-static precautions cannot be observed, personal grounding
may be achieved by touching an earthed metal chassis or component
prior to handling the module.
