Installation Precautions

CAUTION Before performing any of the following procedures, read and follow the safety instructions located in your Product Information Guide.

CAUTION Observe the following points before performing the procedures in this section:

•Ensure that the rack or cabinet housing the device is adequately secured to prevent it from becoming unstable and/or falling over.

•Ensure that the power source circuits are properly grounded.

•Observe and follow the service markings. Do not service any device except as explained in the system documentation. Opening or removing covers marked with a triangular symbol with a lighting bolt may cause electrical shock. These components are to be serviced by trained service technicians only.

•Ensure that the power cable, extension cable, and/or plug is not damaged.

•Ensure that the device is not exposed to water.

•Ensure that the device is not exposed to radiators and/or heat sources.

•Ensure that the cooling vents are not blocked.

•Do not push foreign objects into the device, as it may cause a fire or electric shock.

•Use the device only with approved equipment.

•Allow the device to cool before removing covers or touching internal equipment.

•Ensure that the device does not overload the power circuits, wiring, and over-current protection. To determine the possibility of overloading the supply circuits, add together the ampere ratings of all devices installed on the same circuit as the device. Compare this total with the rating limit for the circuit.

•Do not install the device in an environment where the operating ambient temperature might exceed 40ºC (104ºF).

•Ensure that the airflow around the front, sides, and back of the device is not restricted.
