ESD Caution:

Circuit boards and drives contain electronic components that are extremely sensitive to 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 along their connector edges.
Use a Antistatic Wrist strap. Attach one end of the strap to your wrist and the other end to the chassis, depending on what type of strap you use, with the adhesive end or the metal plug.
Use an Antistatic Mat. Place ESD-sensitive components such as motherboards, memory, and other PCBs on an antistatic mat.

Contamination Caution:

Dust particles of packaging material are number one cause of datacenter contamination. Make sure to remove all packaging material, up to the ESD safe packaging material, while still being outside the datacenter.

NOTICE: The component specified for replacement in this action plan requires a Genie Lift. The lift is required not only for the safety of the servicing engineer, but also for the successful implementation of the replacement procedure. Any of the following parts may be ordered to satisfy the Genie Lift requirement:

370-4286 Genie Lift w/straddle base
371-4170 Genie Lift w/Cntr-weight Base Adj
370-6889 Genie Lift w/counter-weight base
370-6888 Genie Lift w/standard base

Depending on the region/country, the order lead-time for the Genie Lift may be longer than other parts.

DO NOT ATTEMPT THE REPLACEMENT PROCEDURE WITHOUT THE REQUIRED GENIE LIFT.
