Give special consideration to the effect of a lightning strike in your vicinity,
especially if the wiring exceeds the recommended distances, or if it passes
between buildings. The electromagnetic pulse (EMP) caused by lightning or other
high-energy phenomena can easily induce enough energy into unshielded
conductors to destroy electronic devices. If you have experienced EMP problems
in the past, you may want to consult experts in electrical surge suppression and
shielding.
Most data centers cannot resolve infrequent but potentially catastrophic problems
without pulse meters and other special equipment. In addition, these problems can
take a great deal of time to identify and resolve. We recommend that you take the
necessary precautions to avoid these problems by providing a properly grounded
and shielded environment, with special attention to issues of electrical surge
suppression.
The following sections contain detailed cabling and signal information for all
interface and port connections to the GRP. It also provides information for
Ethernet routing and equipment.
Ports labeled Ethernet, 10BASE-T, Token Ring, Console, and AUX are safety
extra-low voltage (SELV) circuits. Only connect SELV circuits to other SELV
circuits.
