Caution notices
A caution notice calls attention to a situation that is potentially hazardous to
people because of some existing condition. A caution notice can be accompanied
by different symbols, as in the examples below:
If the symbol is... It means....
A hazardous electrical condition with less severity than
electrical danger.
A generally hazardous condition not represented by other
safety symbols.
A hazardous condition due to the use of a laser in the
product. Laser symbols are always accompanied by the
classification of the laser as defined by the U. S.
Department of Health and Human Services (for example,
Class I, Class II, and so forth).
Attention notices
An attention notice indicates the possibility of damage to a program, device, or
system, or to data. An exclamation point symbol may accompany an attention
notice, but is not required. A sample attention notice follows:
Attention: Do not bend a fibre cable to a radius less than 5 cm (2 in.);
you can damage the cable. Tie wraps are not recommended for optical
cables because they can be easily overtightened, causing damage to the
cable.
Safety notices v

Rack safety
Rack installation
About this task
DANGER
Observe the following precautions when working on or around
your IT rack system:
vHeavy equipment - personal injury or equipment damage might
result if mishandled.
vAlways lower the leveling pads on the rack cabinet.
vAlways install stabilizer brackets on the rack cabinet.
vTo avoid hazardous conditions due to uneven mechanical
loading, always install the heaviest devices in the bottom of the
rack cabinet. Always install servers and optional devices starting
from the bottom of the rack cabinet.
vRack-mounted devices are not to be used as shelves or work
spaces. Do not place objects on top of rack-mounted devices.
vEach rack cabinet might have more than one power cord. Be
sure to disconnect all power cords in the rack cabinet when
directed to disconnect power during servicing.
vConnect all devices installed in a rack cabinet to power devices
installed in the same rack cabinet. Do not plug a power cord
from a device installed in one rack cabinet into a power device
installed in a different rack cabinet.
vAn electrical outlet that is not correctly wired could place
hazardous voltage on the metal parts of the system or the
devices that attach to the system. It is the responsibility of the
customer to ensure that the outlet is correctly wired and
grounded to prevent an electrical shock.
(R001 part 1 of 2)
Safety notices vii

CAUTION:
vDo not install a unit in a rack where the internal rack ambient temperatures
will exceed the manufacturer's recommended ambient temperature for all your
rack-mounted devices.
vDo not install a unit in a rack where the air flow is compromised. Ensure that
air flow is not blocked or reduced on any side, front, or back of a unit used
for air flow through the unit.
vConsideration should be given to the connection of the equipment to the
supply circuit so that overloading of the circuits does not compromise the
supply wiring or overcurrent protection. To provide the correct power
connection to a rack, refer to the rating labels located on the equipment in the
rack to determine the total power requirement of the supply circuit.
v(For sliding drawers.) Do not pull out or install any drawer or feature if the rack
stabilizer brackets are not attached to the rack. Do not pull out more than one
drawer at a time. The rack might become unstable if you pull out more than
one drawer at a time.
v(For fixed drawers) This drawer is a fixed drawer and should not be moved for
servicing unless specified by manufacturer. Attempting to move the drawer
partially or completely out of the rack may cause the rack to become unstable
or cause the drawer to fall out of the rack.
(R001 part 2 of 2)
viii IBM System Storage: N7000 Series Hardware and Service Guide

Rack relocation (19" rack)
About this task
CAUTION:
Removing components from the upper positions in the rack cabinet improves
rack stability during relocation. Follow these general guidelines whenever you
relocate a populated rack cabinet within a room or building:
vReduce the weight of the rack cabinet by removing equipment starting at the
top of the rack cabinet. When possible, restore the rack cabinet to the
configuration of the rack cabinet as you received it. If this configuration is not
known, you must do the following:
– Remove all devices in the 32U position and above.
– Ensure that the heaviest devices are installed in the bottom of the rack
cabinet.
– Ensure that there are no empty U-levels between devices installed in the
rack cabinet below the 32U level.
– If the rack cabinet you are relocating is part of a suite of rack cabinets,
detach the rack cabinet from the suite.
– Inspect the route that you plan to take when moving the rack to eliminate
potential hazards.
– Verify that the route that you choose can support the weight of the loaded
rack cabinet. Refer to the documentation that came with your rack cabinet
for the weight of a loaded rack cabinet.
– Verify that all door openings are at least 760 x 2030 mm (30 x 80 in.).
– Ensure that all devices, shelves, drawers, doors, and cables are secure.
– Ensure that the four leveling pads are raised to their highest position.
– Ensure that there is no stabilizer bracket installed on the rack cabinet
during movement.
– Do not use a ramp inclined at more than ten degrees.
– Once the rack cabinet is in the new location, do the following:
- Lower the four leveling pads.
- Install stabilizer brackets on the rack cabinet.
- If you removed any devices from the rack cabinet, repopulate the rack
cabinet from the lowest position to the highest position.
– If a long distance relocation is required, restore the rack cabinet to the
configuration of the rack cabinet as you received it. Pack the rack cabinet in
the original packaging material, or equivalent. Also, lower the leveling
pads to raise the casters off of the pallet and bolt the rack cabinet to the
pallet.
(R002)
Fire suppression systems
A fire suppression system is the responsibility of the customer. The customer's own
insurance underwriter, local fire marshal, or a local building inspector, or both,
should 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.
