HANDLING PRECAUTIONS
FOR
STATIC-SENSITIVE DEVICES
This product is designed to protect
sensitive components from damage
due to electrostatic discharge (ESD)
during normal operation. When
performing installation procedures,
however, take proper static control
precautions to prevent damage to
equipment. If you are not sure of the
proper static control precautions,
contact your nearest sales or service
representative.
One 72-inch cabinet can hold up to six carriers;
however, a cabinet does not need to be fully populated.
Follow these rules during installation.
• Install carriers from the bottom of the cabinet and
work up. This provides the following:
— Proper alignment for subsequent carriers.
— Easier installation since the carriers can be
lowered onto the mounting screws from above.
— Convenient connection of the DTE interface.
— Proper cabinet balance. Bottom-up installation
keeps the cabinet from becoming top heavy.
• Install empty carriers in the cabinet.
