Safety Precautions
Make sure the cabinet protection earth ground cable and subrack protection earth ground cable
are well grounded before powering on the equipment. Check and ensure that the insulation
resistance and ground resistance meet the specification.
Grounding Requirements
Caution
Different types of cables on the installation site should be laid out independently and bound
separately. Please note that optical fibers should be bound with dedicated fiber binding straps.
Exercise care if you must bend fibers. If bends are necessary, the fiber bending radius should
not be smaller than 10 D (“D” refers to the fiber diameter) and should not be smaller than 30
mm.
Cables are bound with appropriate tightness and even distance between cable ties. The cable
ties are arranged in good order, and the extra parts of ties are cut from the root without leaving
sharp points.
Binding Cables
Caution
Prior to equipment installation, inspect the equipment room, cabinets, power supplies, cables
(especially earth ground cables), and supporting facilities. After confirming that the conditions for
installation are satisfactory, start the work following project design documents.

Carpets or other materials that easily generate static electricity should not be used on the floor of
the equipment room.
Do not touch any components or wires on cards, or metal conductors in sockets. ESD protection
measures should be taken if it is necessary to touch the card during maintenance.

Caution
To prevent laser radiation from injuring eyes, do not look into the
end face of a fiber or fiber connector directly with naked eyes.
