Safety and environmental notices ix

DANGER
Main Protective Earth (Ground):
This symbol is marked on the frame of the rack.
The PROTECTIVE EARTHING CONDUCTORS should be terminated at that
point. A recognized or certified closed loop connector (ring terminal) should
be used and secured to the frame with a lock washer using a bolt or stud.
The connector should be properly sized to be suitable for the bold or stud,
the locking washer, the rating for the conducting wire used, and the
considered rating of the breaker. The intent is to ensure the frame is
electrically bonded to the PROTECTIVE EARTHING CONDUCTORS. The
hole that the bolt or stud goes into where the terminal conductor and the lock
washer contact should be free of any non-conductive material to allow for
metal to metal contact. All PROTECTIVE EARTHING CONDUCTORS
should terminate at this main protective earthing terminal or at points
marked with . (R010)
Special caution and safety notices
This information describes special safety notices that apply to the Storwize V7000
Unified. These notices are in addition to the standard safety notices supplied and
address specific issues relevant to the equipment provided.
General safety
When you service the Storwize V7000 Unified, follow general safety guidelines.
Use the following general rules to ensure safety to yourself and others:
vObserve good housekeeping in the area where the devices are kept during and
after maintenance.
vFollow the guidelines when lifting any heavy object:
1. Ensure that you can stand safely without slipping.
2. Distribute the weight of the object equally between your feet.
3. Use a slow lifting force. Never move suddenly or twist when you attempt to
lift.
4. Lift by standing or by pushing up with your leg muscles; this action removes
the strain from the muscles in your back. Do not attempt to lift any objects that
weigh more than 18 kg (40 lb) or objects that you think are too heavy for you.
vDo not perform any action that causes a hazard or that makes the equipment
unsafe.
vBefore you start the device, ensure that other personnel are not in a hazardous
position.
vPlace removed covers and other parts in a safe place, away from all personnel,
while you are servicing the unit.
vKeep your tool case away from walk areas so that other people will not trip over
it.
xStorwize V7000 Unified: Problem Determination Guide 2073-720

vDo not wear loose clothing that can be trapped in the moving parts of a device.
Ensure that your sleeves are fastened or rolled up above your elbows. If your
hair is long, fasten it.
vInsert the ends of your necktie or scarf inside clothing or fasten it with a
nonconducting clip, approximately 8 cm (3 in.) from the end.
vDo not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your
clothing.
Remember: Metal objects are good electrical conductors.
vWear safety glasses when you are: hammering, drilling, soldering, cutting wire,
attaching springs, using solvents, or working in any other conditions that might
be hazardous to your eyes.
vAfter service, reinstall all safety shields, guards, labels, and ground wires.
Replace any safety device that is worn or defective.
vReinstall all covers correctly after you have finished servicing the unit.
Handling static-sensitive devices
Ensure that you understand how to handle devices that are sensitive to static
electricity.
Attention: Static electricity can damage electronic devices and your system. To
avoid damage, keep static-sensitive devices in their static-protective bags until you
are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following
precautions:
vLimit your movement. Movement can cause static electricity to build up around
you.
vHandle the device carefully, holding it by its edges or frame.
vDo not touch solder joints, pins, or exposed printed circuitry.
vDo not leave the device where others can handle and possibly damage the
device.
vWhile the device is still in its antistatic bag, touch it to an unpainted metal part
of the system unit for at least two seconds. (This action removes static electricity
from the package and from your body.)
vRemove the device from its package and install it directly into your Storwize
V7000 Unified, without putting it down. If it is necessary to put the device
down, place it onto its static-protective bag. (If your device is an adapter, place it
component-side up.) Do not place the device onto the cover of the Storwize
V7000 Unified or onto a metal table.
vTake additional care when you handle devices during cold weather because
heating reduces indoor humidity and increases static electricity.
Sound pressure
Attention: Depending on local conditions, the sound pressure can exceed 85
dB(A) during service operations. In such cases, wear appropriate hearing
protection.
