Chapter 2 Preparing to Install the WAVE-574
Safety Guidelines
The power cable must be rated for the product and for the voltage and current
marked on the product’s electrical ratings label. The voltage and current
rating of the cable should be greater than the ratings marked on the product.
•
To help prevent electric shock, plug the system components 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.
•
Observe power strip ratings. Make sure that the total ampere rating of all
products plugged into the power strip does not exceed 80 percent of the power
strip ampere ratings limit.
•
Do not use appliance or voltage converters or kits sold for appliances with
your product.
•
To help protect your system components from sudden, transient increases and
decreases in electrical power, use a surge suppressor, line conditioner, or
uninterruptible power supply (UPS).
•
Position cables and power cords carefully; route cables and the power cord
and plug so that they cannot be stepped on or tripped over. Be sure that
nothing rests on your system components’ cables or power cord.
•
Do not modify power cables or plugs. Consult a licensed electrician or your
power company for site modifications. Always follow your local or national
wiring rules.
System Reliability Considerations
To help ensure proper cooling and system reliability, make sure that the following
occurs:
•
Each of the drive bays has either a drive or a filler panel installed.
•
For rack configurations, make sure that space is available around the
appliance to enable the cooling system to work properly. See the
documentation that comes with the rack for additional information.
•
A removed hot-swappable drive is replaced within 2 minutes of removal.
•
Cables for optional adapters are routed according to the instructions provided
with the adapters.
•
A failed fan is replaced within 48 hours.
