ESD Precautions

Wear an antistatic wrist strap at all times when handling any CRU.
■
Before handling any CRU, discharge any static electricity by touching a grounded

After removing a CRU from the cabinet, immediately place it on an antistatic mat.

Do not slide a CRU over any surface.

Limit body movement (which builds up static electricity) during the removal and
