Racking Precautions
CAUTION: Read the following precautions before racking the Harmonic MediaGrid system.
IMPORTANT: For precautions specific to the ContentStore 5840, see Racking Precautions for the
ContentStore 5840 .

Safe handling of this system requires at least TWO people. Harmonic recommends that you
use THREE people to rack mount a system; two to lift and one to help guide the system onto
the rack rails.

When lifting the system, two people at either end should lift slowly with their feet spread out
to distribute the weight. When lifting, always keep your back straight and lift with your legs.

Ensure that the leveling jacks on the bottom of the rack are fully extended to the floor with the
full weight of the rack resting on them.

In single rack installation, stabilizers should be attached to the rack. In multiple rack
installations, the racks should be coupled together.

Load the rack from the bottom to the top, with the heaviest component at the bottom of the
rack.

Always make sure the rack is stable before extending a component from the rack.

You should extend only one component at a time--extending two or more simultaneously
may cause the rack to become unstable.

To eliminate any possibility of tipping over, ensure that the equipment rack is securely
fastened to the floor or wall.
Additional Racking Precautions for the ContentServer and ContentStore 4000 Series

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.

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 ContentServer 4000 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.
