Laser Safety
● Laser beams will cause eye damage. Do not look into bores of optical modules
or optical bers without eye protection.
● Cover ber connectors with dust caps when they are not connected.
Mechanical Safety
● Wear protective gloves when you are moving the device.
● Use safe lifting practices when moving the equipment. Never attempt to lift
objects that are too heavy for one person to handle. Instead, seek help or use
appropriate tools.
● Before installing the chassis into or removing it from a cabinet, ensure there are
no objects that could fall from the cabinet and cause injury.
● If main control boards, service boards, and power modules have been installed
on the chassis, you are advised to remove them before moving the chassis to
prevent them from falling
o and causing injury.
● Do not drill unapproved holes into a cabinet, as doing so may impair its
electromagnetic shielding and damage cables inside. In addition, drilling holes
produces metal shavings that may enter the cabinet and cause short circuits on
printed circuit boards (PCBs).
