Equipment Mounting Guidelines
Follow these guidelines when mounting equipment:
❖
Make sure there is adequate room for all devices and cabling.
❖
Calculate the total weight and the power requirements of the components prior to
installation.
❖
Mount equipment starting at the bottom of the rack moving upward. To increase
stability, mount the heaviest components as close to the bottom of the rack as
possible. Unused space should be at the top of the rack.
