ESD Guidelines

Figure: Working in an ESD-Protected Environment

Observe the following electrostatic discharge (ESD) guidelines whenever servicing

electronic components:

Obtain an ESD protection kit and follow the directions that come with the kit. You can

purchase an ESD kit from HP (T99247-A00) or from a local electronics store. Ensure

that your ESD wriststrap has a built-in series resistor and that the kit includes an

antistatic table mat.

●

Before you unpack a replacement CRU or FRU, place the CRU or FRU package on

the antistatic table mat and attach the grounding clip on your wriststrap to the mat.

●

When you unpack the CRU or FRU, do not cut into the ESD protective bag

surrounding the CRU or FRU. The protective bag protects the CRU or FRU and can

be reused for storing the CRU or FRU that has been replaced.

●

Before you move the CRU or FRU from the antistatic table mat, attach the grounding

clip from your ESD wriststrap to any unpainted metal surface on the CRU or FRU

frame.

●

Before you bring a CRU or FRU in contact with a system enclosure, attach the

grounding clip on your ESD wriststrap to any unpainted metal surface on the

enclosure frame.

●

When you remove a CRU or FRU from a system enclosure, first pull the CRU or FRU

partway out of the slot and then attach the grounding clip on your ESD wriststrap to

any unpainted metal surface on the CRU or FRU frame.

●

Store CRUs or FRUs that require ESD protection in ESD protective bags.●

The figure Working in an ESD-Protected Environment illustrates how to use an ESD

kit when servicing CRUs or FRUs.
