Racking precautions for the MediaStore 7200
Follow the necessary precautions when racking the MediaStore 7200.
• The rack design should take into consideration the maximum operating ambient temperature, which is
35°C.
• Disconnect power cords from your system before rack mounting.
• The MediaStore 7200 weighs approximately 29 kg (64 lb) without disk drives installed. The design
should incorporate stabilizing features suitable to prevent the rack from tipping or being pushed over
during installation or in normal use.
• Do not open the system’s top cover. If opening the cover for maintenance is a must, only a trained
technician should do so.
• The openings on the enclosure are for air convection to protect the equipment from overheating. DO
NOT COVER THE OPENINGS.
• The MediaStore 7200 must only be operated from a power supply input voltage range of 100 to 240
VAC, 47 to 63 Hz. Make sure the voltage of the power source is within the specification on the label
when connecting the equipment to the power outlet.
• Place power cords out of the way of foot traffic. Do not place anything over the power cord.
• Make sure the voltage of the power source is within the specification on the label when connecting
the equipment to the power outlet. The current load and output power of loads shall be within the
specification.
IMPORTANT:
• Use only the power cables provided by Harmonic.
• The MediaStore must be connected to reliable grounding before applying power.
• The MediaStore will not receive sufficient airflow or cooling if it is operated with any of
the front or rear modules missing. It is essential that every module bay is filled either
with a module or a blank module.
