Integrating Hardware
This section describes the hardware tasks required to attach devices to the Open SCSI
bus, and lists specifications for necessary hardware.
Electrostatic Discharge (ESD) Precautions
Observe these ESD guidelines whenever servicing electronic components:
•
Obtain an electrostatic discharge (ESD) protection kit and follow the directions that
come with the kit. Ensure that your ESD wriststrap has a built-in series resistor and
that the kit includes an antistatic table mat.
You can purchase an ESD kit from a local electronics store or from Hewlett-
Packard. For the part number of the ESD kit available from HP, refer to the
Himalaya S-Series Hardware Support Guide.
•
Before you unpack a CRU, place the CRU package on the antistatic table mat and
attach the grounding clip on your wriststrap to the mat.
•
When you unpack a CRU, do not cut into the ESD protective bag surrounding the
CRU. The bag protects the CRU and can be reused for storing a CRU.
•
Before you move the CRU from the antistatic table mat, attach the grounding clip
from your ESD wriststrap to any unpainted metal surface on the CRU frame.
•
Before you bring the CRU 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 from a system enclosure, first pull the CRU partway out
of the slot and then attach the grounding clip on your ESD wriststrap to any
unpainted metal surface on the CRU frame.
•
Store CRUs that require ESD protection in ESD-protective bags.
