wearing a grounded wrist strap) may reset the processor or damage
electronic components, resulting in interrupted operations.
When working on units located in a hazardous area (where explosive
gases may be present), make sure the area is in a non-hazardous state
before performing procedures. Performing these procedures in a
hazardous area could result in personal injury or property damage.
To remove the CPU module:
1.
Perform the backup procedure described in
Preserving
