HP 6400.8400 Enterprise Virtual Array - Manual (Page 79)

Replacing the failed component
CAUTION: Components can be damaged by electrostatic discharge. Use proper anti-static
protection.
•
Always transport and store CRUs in an ESD protective enclosure.
•
Do not remove the CRU from the ESD protective enclosure until you are ready to install it.
•
Always use ESD precautions, such as a wrist strap, heel straps on conductive flooring, and
an ESD protective smock when handling ESD sensitive equipment.
•
Avoid touching the CRU connector pins, leads, or circuitry.
•
Do not place ESD generating material such as paper or non anti-static (pink) plastic in an ESD
protective enclosure with ESD sensitive equipment.
•
HP recommends waiting until periods of low storage system activity to replace a component.
•
When replacing components at the rear of the rack, cabling may obstruct access to the
component. Carefully move any cables out of the way to avoid loosening any connections.
In particular, avoid cable damage that may be caused by:
◦ Kinking or bending.
◦ Disconnecting cables without capping. If uncapped, cable performance may be impaired
by contact with dust, metal or other surfaces.
◦ Placing removed cables on the floor or other surfaces, where they may be walked on or
otherwise compressed.
