To help prevent electric shock, plug the system and peripheral power cables into properly grounded
electrical outlets. These cables are equipped with three-prong plugs to help ensure proper grounding. Do
not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cable,
use a 3-wire cable with properly grounded plugs.
•
Observe extension cable and power strip ratings. Make sure that the total ampere rating of all products
plugged into the extension cable or power strip does not exceed 80 percent of the ampere ratings limit
for the extension cable or power strip.
•
To help protect your system from sudden, transient increases and decreases in electrical power, use a
surge suppressor, line conditioner, or uninterruptible power supply (UPS).
•
Position system cables and power cables carefully; route cables so that they cannot be stepped on or
tripped over. Be sure that nothing rests on any cables.
•
Do not modify power cables or plugs. Consult a licensed electrician or your power company for site
modifications. Always follow your local/national wiring rules.
•
When connecting or disconnecting power to hot-pluggable power supplies, if offered with your system,
observe the following guidelines:
– Install the power supply before connecting the power cable to the power supply.
– Unplug the power cable before removing the power supply.
– If the system has multiple sources of power, disconnect power from the system by
unplugging
all
power cables from the power supplies.
•
Move products with care; ensure that all casters and/or stabilizers are firmly connected to the system.
Avoid sudden stops and uneven surfaces.
General Precautions for Rack-Mountable Products
Observe the following precautions for rack stability and safety. Also refer to the rack installation documentation
accompanying the system and the rack for specific caution statements and procedures.
Systems are considered to be components in a rack. Thus, "component" refers to any system as well as to various
peripherals or supporting hardware.
CAUTION:
Installing systems in a rack without the front and side stabilizers
installed could cause the rack to tip over, potentially resulting in bodily injury under
certain circumstances. Therefore, always install the stabilizers before installing
components in the rack.
After installing system/components in a rack, never pull more than one component
out of the rack on its slide assemblies at one time. The weight of more than one
extended component could cause the rack to tip over and may result in serious
injury.
•
Before working on the rack, make sure that the stabilizers are secured to the rack, extended to the floor,
and that the full weight of the rack rests on the floor. Install front and side stabilizers on a single rack or
front stabilizers for joined multiple racks before working on the rack.
Always load the rack from the bottom up, and load the heaviest item in the rack first.
Make sure that the rack is level and stable before extending a component from the rack.
