When you install equipment in a rack, load heavier devices in the lower half of the rack
•
first to avoid making the rack top-heavy.
Only use tools and equipment that are in perfect condition. Do not use equipment with
•
visible damage.
Route cables in a manner that prevents possible damage to the cables and avoids
•
causing accidents, such as tripping.
Installing Power Supply Units
For the ratings and power requirements of each power supply unit, see
Technical Specifications
WARNING!
Be sure that the requirements listed in this section are satisfied
when installing all power supplies.
When you install power supplies:
Plug power supplies only into properly grounded electrical outlets to help prevent
•
electrical shock and comply with international safety standards.
Use only power cords that are certified for use within the country of use. Do not attempt to
•
modify AC power cords.
Make sure the wall outlet is installed near the equipment and is easily accessible for quick
•
disconnect.
Make sure the voltage and frequency of your power outlet match the system electrical
•
ratings for the equipment. The building and/or power source has to provide overload
protection.
Use a surge suppressor, line conditioner, or uninterruptible power supply to protect the
•
system from momentary increases or decreases in electrical power.
When inserting a hot-swappable power supply into the bay, do not use excessive force.
•
When you install multiple power supplies, connect each power supply to a different,
•
independent over-current protection device, such as a circuit breaker. If a single power
source fails, it will affect only that power supply to which it is connected. If all the power
supplies on a single switch are connected to the same power source, the entire switch is
vulnerable to a power failure.
WARNING!
The power supplies do not have switches for turning the unit on
and off. Remove the wall plug from the electrical outlet to
disconnect the power from an AC power supply. Make sure that
this connection is easily accessible.
