Installation Overview
Standard Operating Practices
When you handle a customer-replaceable unit (CRU), follow standard operating
practices to minimize any potential damage to the equipment:
•
When handling CRUs, work in an environment protected from electrostatic
discharge (ESD). See Using ESD Protection on page 1-6.
•
Obtain an ESD protection kit and follow the directions that come with the kit. You
can purchase ESD kits from HP using the part number given in the NTL Support
and Service Library. See Support and Service Library on page xxiv.
•
Make sure any ESD wriststrap has a built-in series resistor and includes an
antistatic table mat.
•
Before unpacking CRUs, place the packing container on an antistatic table mat.
•
CRUs that require ESD protection are shipped in ESD protective bags. When
opening packing containers for these CRUs, do not cut the ESD protective bag.
•
Before moving a CRU from an antistatic table mat, attach the grounding clip from
your ESD wriststrap to any exposed unpainted metal surface on the CRU frame.
•
Before you bring the CRU in contact with the system enclosure, attach the
grounding clip to any exposed unpainted metal surface on the enclosure frame.
•
When removing a CRU from an enclosure, once you have pulled the CRU partway
out of the slot, attach the grounding clip from your ESD wriststrap to any exposed
unpainted metal surface on the CRU frame.
•
Before setting a CRU on an antistatic table mat, attach the grounding clip from your
ESD wriststrap to the antistatic table mat.
•
Store CRUs that require ESD protection in ESD protective bags.
•
Install or upgrade only hardware components that are designated
customer-replaceable units (CRUs) and for which this guide includes installation
procedures.
•
Before any installation procedure, inspect the CRU. Check connectors for bent or
broken pins and look for any other obvious damage.
•
When installing a CRU that is located on the appearance side of the enclosure,
work quickly to minimize the amount of time that the enclosure door is left open.
•
Before working with electrical equipment, remove all metal accessories, such as
rings, watches, and necklaces, that can damage the equipment.
•
Before working with electromechanical equipment, restrain items such as long hair
and sleeves that can get caught in the equipment.
