General Safety Precautions
Follow these guidelines:
Do not try to lift objects that you think are too heavy for you.
When you install equipment in a rack, load heavier devices in the lower half of the rack first to avoid making the rack top-heavy.
Use only tools and equipment that are in perfect condition. Do not use equipment with visible damage.
Route cables in a manner that prevents possible damage to the cables and avoids causing accidents, such as tripping.
Do not place a monitor or other objects on top of the equipment. The chassis cover is not designed to support weight.
To reduce the risk of fire, use only #26 AWG or larger telecommunications line cord. Use only copper conductors.
Do not work on the system or connect or disconnect cables during periods of lightning activity.
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor.
