Using electrostatic discharge prevention procedures
Always follow the electrostatic discharge (ESD) prevention procedure when you remove and replace
cards. Failure to follow the ESD prevention procedure can result in permanent or intermittent card
failures.
CAUTION
Observe all precautions for electrostatic discharge.
WARNING!
To avoid electrical shock, never wear the ESD wrist strap while working on the power system or at the back of the
cabinet.
To perform ESD prevention procedures:
1 Check the ESD wrist strap weekly to ensure proper ESD protection (refer to
wrist strap" on page 85
2 Attach the ESD wrist strap to your bare wrist. Ensure that the inside of the strap makes good contact
with your skin (see Figure 7-2).
3 Attach one end of the coiled wire to the wrist strap and the other end to the alligator clip, if
necessary.
4 Connect the alligator clip to an unpainted portion of the cabinet frame. This safely channels
electrostatic charges to ground.
