Special caution and safety notices
This information describes special safety notices that apply to the FlashSystem
A9000R. These notices are in addition to the standard safety notices supplied and
address specific issues relevant to the equipment provided.
Laser safety
When using an NVRAM5 or NVRAM6 cluster media converter, the storage system
must be installed in a restricted access location.
CAUTION:
This product contains a Class 1M laser. Do not view directly with optical
instruments. (C028)
This equipment contains Class 1 laser products, and complies with FDA radiation
regulations 21 CFR Subchapter J, international laser safety standard IEC 60825
parts -1 and -2, and relevant national standards based on these.
CAUTION:

links with laser modules that operate at greater than Class 1 power levels. For
this reason, never look into the end of an optical fiber cable or open receptacle.
(C027)
Attention: In the United States, use only SFP or GBIC optical transceivers that
comply with the FDA laser registration, reporting and accessions per the Center for
Devices and Radiological Health (CDRH) according to 21 CFR Subchapter J.
Internationally, use only SFP or GBIC optical transceivers that comply with IEC
standard 60825–1. Optical products that do not comply with these standards might
produce light that is hazardous to the eyes.
xii IBM FlashSystem A9000R Models 9835-415 and 9837-415 Deployment Guide

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.
Note: For power cables outside of the U.S., IBM provides power cables with no
connector. It is the client's responsibility to install the correct power plug with the
aide of a certified electrician. For power requirements, see “Power requirements”
on page 26.
Safety and environmental notices xiii

Sound pressure
Hearing protection must be worn while you service the FlashSystem A9000R
system.
Attention: Depending upon local conditions, the sound pressure might exceed 85
dB(A) during service operations. When working on the FlashSystem A9000R
system while either the front or rear door is in the open position, hearing
protection must be worn.
CAUTION:
Depending upon local conditions, the sound pressure might exceed 85
dB(A) during service operations. Hearing protection must be worn when you are
in a room that has an FlashSystem A9000R system while either the front or rear
door is open or when the front and rear doors are not installed.
Leakage current
The FlashSystem A9000R system incorporates 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.
For the most reliable operation, do not use Ground Fault Circuit Interrupter
(GFCI), Earth Leakage Circuit Breaker (ELCB), and Residual Current Circuit
Breaker (RCCB) type circuit breakers with a FlashSystem A9000R system. The
FlashSystem A9000R system is certified for safe operation and is compliant with
IEC, EN, UL, CSA 60950-1 standards. However, if leakage detection circuit breakers
are required by local electrical practice, the breakers must be sized for a
leakage-current rating of 300 mA or greater to reduce the risk of server outage
caused by erroneous and spurious tripping.
Site preparation
The IBM service representative can only minimally reposition the rack at the
installation site, as needed to service the FlashSystem A9000R system. The
customer is responsible for using professional movers or riggers in the case of
equipment relocation or disposal.
xiv IBM FlashSystem A9000R Models 9835-415 and 9837-415 Deployment Guide

Attention: Do not tilt the FlashSystem A9000R system rack more than 10 degrees.
10
fsa9k071
If more clearance is needed for FlashSystem A9000R or racks the height-reduced
shipping (feature code AFR2) should be ordered to reduce the height of the rack.
When the height-reduced feature is ordered, the top cover is removed before the
IBM FlashSystem®A9000R is moved to its final location by professional movers.
The top cover must be installed during the IBM FlashSystem A9000R installation.
If tilting or weight-reduction is needed for IBM FlashSystem A9000R or rack
shipment, the weight-reduced shipping (feature code AFR3) should be ordered to
reduce the weight of the rack.
When the weight-reduced feature is ordered grid controllers and flash enclosures
are shipped separately: this allows the rack to be tilted as much as necessary in
order to fit under low doorways. As a result, these components must be installed
during IBM FlashSystem A9000R installation.
IBM FlashSystem A9000R arrives fully assembled with all components in place,
unless the weight or height reduced shipping options is ordered.
If the site does not meet the delivery clearances and the height-reduced shipping is
ordered, the doors, side panels, and rack top cover of the rack must be removed
before moving to the final location.
Safety and environmental notices xv

DANGER
Heavy equipment - personal injury or equipment damage might result if
mishandled. Use only professional movers.
