Huawei AR Series - 2.2 Checking the Installation Site

Electrical Safety
DANGER
l Direct contact with a high-voltage power source or indirect contact through damp objects
can be fatal. Misoperations on high-voltage facilities may result in fire, electric shock, or
other accidents.
l Never install or remove the equipment or power cables while the power is on. The electric
arc or spark generated between a power cable and conductor may cause fire or eye
damage.
l To protect personal and equipment safety, ground the equipment before powering it on.
Laser Safety
CAUTION
l Invisible laser beams will cause eye damage. Do not look into bores of optical modules or
connectors of optical fibers without eye protection.
l After unplugging an optical fiber, cover the fiber connectors with dust caps.
Mechanical Safety
CAUTION
l Before carrying a heavy object, use appropriate tools to protect yourself from bruise or
sprain.
l Before pulling the equipment out of the cabinet/rack, check whether there are any unstable
or heavy objects on the cabinet/rack. Be careful not to make the objects fall, which may
cause body injuries.
l Do not drill holes on a cabinet without permission. Unqualified holes on a cabinet affect
the electromagnetic filter performance of the cabinet and cause damages to the cables in
the cabinet. In addition, metal scraps may fall into the cabinet when you are drilling holes,
causing short circuit on printed circuit boards (PCBs).
2.2 Checking the Installation Site
Before installing the equipment, ensure that the environment in the installation site meet
equipment operation requirements.
Heat Dissipation
There must be more than 100 mm clearance around the equipment for heat dissipation.
