static electricity. Ordinary amounts of static electricity from clothing or the work
environment can destroy the components located on these boards. Do not touch the
components without using antistatic precautions, especially along the connector edges.

Required Tools and Information

The following tools are needed to service the CRUs:
Antistatic wrist strap - Wear an antistatic wrist strap and use an antistatic mat when
■
handling components such as HDDs, LCCs, or PCI cards. When servicing or removing
storage controller components, attach an antistatic strap to your wrist and then to a metal
area on the chassis. Following this practice equalizes the electrical potentials between you
and the storage controller.
Antistatic mat - Place static-sensitive components on an antistatic mat.
