Safety and environmental notices
This section contains information about:
v“Safety notices and labels”
v“Rack safety” on page xx
v“Environmental notices” on page xx
Safety notices and labels
When using this product, observe the danger, caution, and attention notices
contained in this guide. The notices are accompanied by symbols that represent the
severity of the safety condition. The danger and caution notices are listed in
numerical order based on their IDs, which are displayed in parentheses, for
example (D004), at the end of each notice. Use this ID to locate the translation of
these danger and caution notices in the Safety Notices publication that is shipped
with this product.
The following notices and statements are used in IBM documents. They are listed
below in order of increasing severity of potential hazards. Follow the links for
more detailed descriptions and examples of the danger, caution, and attention
notices in the sections that follow.
vNote: These notices provide important tips, guidance, or advice.
v“Attention notices” on page xx: These notices indicate potential damage to
programs, devices, or data.
v“Cautions”: These statements indicate situations that can be potentially
hazardous to you.
v“Danger notices” on page xv: These statements indicate situations that can be
potentially lethal or extremely hazardous to you. Safety labels are also attached
directly to products to warn of these situations.
vIn addition to these notices, “Safety labels” on page xviii may be attached to the
product to warn of potential hazards.
Cautions
A Caution statement alerts you to situations that can be potentially hazardous to
you or cause damage to hardware, firmware, software, or data.
General cautions
CAUTION:
Changes or modifications made to this device that are not expressly
approved by the party responsible for compliance could void the
user's authority to operate the equipment.
CAUTION:
Disassembling any part of the power supply and fan assembly voids
the warranty and regulatory certifications. There are no
user-serviceable parts inside the power supply and fan assembly.
© Copyright IBM Corp. 2017 xiii

CAUTION:
Make sure the airflow around the front, sides, and back of the device
is not restricted.
CAUTION:
Ensure that the airflow direction of the power supply unit matches
that of the installed fan tray. The power supplies and fan trays are
clearly labeled with either a green arrow with an "E", or an orange
arrow with an "I."
CAUTION:
To protect the serial port from damage, keep the cover on the port
when not in use.
CAUTION:
Never leave tools inside the chassis.
CAUTION:
Use the screws specified in the procedure. Using longer screws can
damage the device.
CAUTION:
To avoid damaging blade and chassis, do not push the blade into a
slot or pull the blade from a slot using the ejector handles.
CAUTION:
Remove the protective cover on the port side of chassis before
applying power. This cover is attached over the air vents. If not
removed, the chassis can overheat and will eventually shut down.
Electrical cautions
CAUTION:
Use a separate branch circuit for each power cord, which provides
redundancy in case one of the circuits fails.
CAUTION:
For the NEBS-compliant installation of a device with AC or DC
systems, use a ground wire of at least 2 AWG. The ground wire
should have an agency-approved crimped connector (provided with
the device) attached to one end, with the other end attached to
building ground. The connector must be crimped with the proper tool,
allowing it to be connected to both ground screws on the enclosure.
Before crimping the ground wire into the provided ground lug, ensure
that the bare copper wire has been cleaned and antioxidant is applied
to the bare wire. In addition, anti-rotation devices or lock washers
must be used with all screw connections for the grounding wire.
xiv SAN512B-6 Installation, Service, and User Guide

CAUTION:
All devices with AC power sources are intended for installation in
restricted access areas only. A restricted access area is a location where
access can be gained only by service personnel through the use of a
special tool, lock and key, or other means of security.
CAUTION:
Before plugging a cable into any port, be sure to discharge the voltage
stored on the cable by touching the electrical contacts to ground
surface.
CAUTION:
Static electricity can damage the chassis and other electronic devices.
To avoid damage, keep static-sensitive devices in their static-protective
packages until you are ready to install them.
CAUTION:
If you do not install a module or a power supply in a slot, you must
keep the slot filler panel in place. If you run the chassis with an
uncovered slot, the system will overheat.
Cautions related to equipment weight
18-32 kg (39.7-70.5 lbs)
svc00167
CAUTION:
Do not use the port cover tabs to lift the module. They are not
designed to support the weight of the module, which can fall and be
damaged.
18-32 kg (39.7-70.5 lbs)
svc00167
CAUTION:
To prevent damage to the chassis and components, never attempt to
lift the chassis using the fan or power supply handles. These handles
were not designed to support the weight of the chassis.
Danger notices
A Danger statement indicates conditions or situations that can be potentially lethal
or extremely hazardous to you. Safety labels are also attached directly to products
to warn of these conditions or situations.
General dangers
DANGER
The procedures in this manual are for qualified service personnel.
DANGER
Be careful not to accidently insert your fingers into the fan tray
while removing it from the chassis. The fan may still be spinning
at a high speed.
Safety and environmental notices xv

DANGER
This equipment is suitable for mounting on concrete or other
noncombustible surfaces only.
Dangers related to equipment weight
18-32 kg (39.7-70.5 lbs)
svc00167
DANGER
Use safe lifting practices when moving the product.
18-32 kg (39.7-70.5 lbs)
svc00167
DANGER
Make sure the rack housing the device is adequately secured to
prevent it from becoming unstable or falling over.
18-32 kg (39.7-70.5 lbs)
svc00167
DANGER
Mount the devices you install in a rack as low as possible. Place
the heaviest device at the bottom and progressively place lighter
devices above.
18-32 kg (39.7-70.5 lbs)
svc00167
DANGER
A completely empty chassis weighs approximately 35.61 kg (78.5 lb)
and requires a hydraulic or assisted lift to install it.
18-32 kg (39.7-70.5 lbs)
svc00167
DANGER
A fully populated chassis weighs approximately 145.83 kg (321.5
lbs) and requires a hydraulic or assisted lift to install it.
xvi SAN512B-6 Installation, Service, and User Guide

18-32 kg (39.7-70.5 lbs)
svc00167
DANGER
If a lift tool with a capacity of at least 350 lbs is not available, the
director chassis must be depopulated completely before installing
it into the rack. Remove the power supplies, fan modules, all of the
blades, the cable management comb, and the chassis door (if
equipped). Install the empty chassis into the rack following the
chassis installation instructions. The weight of the empty chassis is
78.5 lbs (35.6 kg) and must be lifted by minimum 3 people. After
securing the chassis to the rack, reinstall the power supplies, fan
modules, and the blades and proceed with the installation.
Electrical dangers
DANGER
Make sure that the power source circuits are properly grounded,
then use the power cord supplied with the device to connect it to
the power source.
DANGER
Before beginning the installation, see the precautions in “Power
precautions.”
DANGER
For safety reasons, the ESD wrist strap should contain a series 1
megaohm resistor.
DANGER
If the installation requires a different power cord than the one
supplied with the device, make sure you use a power cord
displaying the mark of the safety agency that defines the
regulations for power cords in your country. The mark is your
assurance that the power cord can be used safely with the device.
DANGER
Disconnect the power cord from all power sources to completely
remove power from the device.
Safety and environmental notices xvii

DANGER
High Touch Current. Earth connection essential before connecting
supply.
Laser dangers
DANGER
All fiber-optic interfaces use Class 1 lasers.
DANGER
Use only optical transceivers that are qualified by IBM and comply
with the FDA Class 1 radiation performance requirements defined
in 21 CFR Subchapter I, and with IEC 825 and EN60825. Optical
products that do not comply with these standards might emit light
that is hazardous to the eyes.
DANGER
Laser Radiation. Do Not View Directly with Optical Instruments.
Class 1M Laser Products.
Safety labels
As an added precaution, safety labels are often installed directly on products or
product components to warn of potential hazards. These can be either danger or
caution notices, depending upon the level of the hazard.
The actual product safety labels may differ from these sample safety labels:
DANGER
