Protection against sources of electrical interference
Protect the disk array from sources of electrical interference:
Table 15. Sources of electrical interference
Potential source Description
Wall outlets Convenience power outlets for building maintenance
equipment (such as vacuum cleaners and floor buffers)
must be wired from circuit breakers on a power panel
separate from the computer system panel. The ground
wires from these outlets must be connected to the
normal building distribution panel and not to the
system ground.
If a separate power source and separate ground are not
provided, operation of janitorial equipment can induce
electrical noise and cause abnormal operation of the
computer system. Your electrician can verify whether
maintenance outlets are on separate panels.
Lightning In geographical areas subject to lightning storms, it
may by advisable to install lightning protection for
both personnel and computer systems. The principles
of lightning protection and personnel safety are
outlined in detail in the lightning protection code
contained in the National Fire Protection Association
(NFPA) Handbook.
Electromagnetic
interference
The disk array is specifically designed to reduce its
susceptibility to radiated and conducted interference.
Electromagnetic interference can cause a variety of
system problems. An HP representative can advise you
about the most common causes of electromagnetic
interference.
