Intended Uses

This product was evaluated as Information Technology Equipment (ITE), which may be installed in
central offices, telecommunication centers, network telecommunication facilities, offices, schools,
computer rooms, and similar commercial type locations where the National Electric Code (NEC)
applies. The suitability of this product for other product categories and environments (medical,
industrial, telecommunications, residential, alarm systems, test equipment, and so on), other than an ITE
application, may require further evaluation.
Although CDEs accept both AC and DC power modules, the system does not allow mixing of AC and
Caution
DC power modules in one system.

If AC Power Supplies Are Installed

Source AC power disconnect: The AC power cord is considered the source disconnect for the CDE and
must be readily accessible when installed. If the individual CDE power cords are not readily accessible
for disconnection, you must install an AC power disconnect for the entire rack unit. This main disconnect
must be readily accessible, and it must be labeled as controlling power to the entire rack, not just to the
CDEs.
Use the correct external power source. Operate the product only from the type of power source
indicated on the electrical ratings label. If you are not sure of the type of power source required,
consult your service representative or local power company.
Use only approved power cables. If you have not been provided with a power cable for your system
or for any AC-powered option intended for your system, purchase a power cable that is approved for
use in your country. The power cable must be rated for the product and for the voltage and current
marked on the electrical ratings label of the product. 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.
