components, attach an antistatic strap to your wrist and then to a bare metal area on the chassis.

How to Use an Antistatic Mat
Prepare an antistatic surface to set parts on during the removal, installation, or replacement
process.
Place static-sensitive components such as the printed circuit boards, memory modules, and
CPUs on the antistatic mat. The following items can be used as an antistatic mat:
■
Antistatic bag used to wrap an Oracle replacement part
■
Oracle antistatic mat, part number 250-1088
■
A disposable antistatic mat (shipped with some replacement parts or optional system
components)
Attach an antistatic wrist strap.
When servicing or removing server components, attach an antistatic strap to your wrist and
then to a bare metal area on the chassis.

Oracle Service Technician. A component designated as a CRU has safety and complexity levels
deemed to be suciently within the scope of a non-service personnel. However, if you feel that
servicing a component designated as a CRU exceeds your service capabilities, please contact
Oracle Service.
