IBM XIV Gen3 Series, Руководство по планированию

Страница: 13 / 126

Usage restrictions: The optical ports of the modules must be terminated with an
optical connector or with a dust plug.
Ladder usage
A step or platform ladder might be necessary to service higher modules.
Use an OSHA/CSA approved non-conductive step or platform ladder specified for
at least a 136.4 kg (300 lb.) load capacity.
Fire suppression systems
A fire suppression system is the responsibility of the customer. The insurance
underwriter, local fire marshal, or a local building inspector, or all three, must be
consulted in selecting a fire suppression system that provides the correct level of
coverage and protection.
IBM designs and manufactures equipment to internal and external standards that
require certain environments for reliable operation. Because IBM does not test any
equipment for compatibility with fire suppression systems, IBM does not make
compatibility claims of any kind nor does IBM provide recommendations on fire
suppression systems.
Power cables
Use only IBM approved UL power cables.
For your safety, IBM provides a power cable with a grounded attachment plug to
use with this IBM product. To avoid electrical shock, always use the power cable
and plug with a correctly grounded outlet. IBM power cables used in the United
States and Canada are listed by Underwriters Laboratories (UL) and certified by
the Canadian Standards Association (CSA). For units intended to be operated at
115 volts: Use a UL-listed and CSA-certified cable set consisting of a minimum 18
AWG, Type SVT or SJT, three-conductor cable, a maximum of 15 feet in length and
a parallel blade, grounding-type attachment plug rated 15 amperes, 125 volts. For
units intended to be operated at 230 volts (U.S. use), use a UL-listed and
CSA-certified cable set consisting of a minimum 18 AWG, Type SVT or SJT,
three-conductor cable, a maximum of 15 feet in length and a tandem blade,
grounding-type attachment plug rated 15 amperes, 250 volts. For units intended to
be operated at 230 volts (outside the U.S.), use a cable set with a grounding type
attachment plug. The cable set must have the appropriate safety approvals for the
country in which the equipment is to be installed. IBM power cables for a specific
country or region are usually available only in that country or region.
Connect all power cables to a correctly wired and grounded electrical outlet.
Ensure that the outlets supplies correct voltage and phase rotation according to the
system rating plate. Ensure that all customer facility outlets are protected with
circuit breakers rated at maximum for 30 Amps. The power cable plugs operate as
the system main-disconnection method.
Leakage current
XIV systems incorporate electromagnetic-interference filter capacitors that are
required to prevent electrical noise from penetrating the power grid. A
characteristic of filter capacitors, during normal operation, is a high amount of
leakage current.
Depending on the storage configuration, this leakage current can reach 100 mA.
