Racking Precautions
CAUTION:
Read the following precautions before racking the Harmonic MediaGrid system.
IMPORTANT:
For precautions specific to the ContentStore 5840, see
Rack Mounting the ContentStore
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.
Rack Mounting the Harmonic MediaGrid 3000 Series System
The following steps provide an overview of installing each of the Harmonic MediaGrid
components. A rack mounting kit is provided with each device, which includes the necessary
hardware along with detailed mounting instructions.
For each device, always follow the
instructions in the mounting kit and use the screws that are included with the mounting
hardware
.
IMPORTANT:
If the ContentStore 5840 is part of your system, rack mount this unit first. Refer to
Mounting the ContentStore 5840
for instructions.
NOTE:
Each device should be placed on the rack and then secured to the rails before mounting the next
device.
Rack Mounting the ContentServer 3000 and ContentStore 3160
1. Start at the bottom of the rack with a ContentServer if this is the first device you are mounting.
2. Install the inner rack rails as follows:
a. Extend the inner rail toward the front of the rail assembly as far as possible, then depress
the locking tab to pull it completely out.
b. Place the inner rail on the side of the chassis aligning the hooks of the chassis with the rail
extension holes.
c. Slide the extension toward the front of the chassis.
