Electrical Equipment Guidelines
Follow these basic guidelines when working with any electrical equipment:
Know where the emergency power-off switch is located for the room in which you are working.
Disconnect all power and external cables before moving the chassis.
Do not work alone if potentially hazardous conditions exist.
Never assume that power has been disconnected; always check.
Do not perform any action that makes the equipment unsafe or might create a potential danger to people.
Examine your work area for possible hazards such as ungrounded power extension cables, missing safety grounds, or
wet floors.
CAUTION: Be sure to connect the chassis to protective earth ground before applying power or inserting modules. An
ungrounded chassis may damage components.
CAUTION: The ports of the C4/C4c CMTS chassis are suitable for connection to intra-building or unexposed wiring or
cabling only. The ports of the chassis MUST NOT be metallically connected to interfaces which connect to outside plant
(OSP) or its wiring. These interfaces are designed for use as intra-building interfaces only, requiring isolation from the
exposed OSP cabling. They are Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4. Finally, the addition of
Primary Protectors is not sufficient protection from electrical shock in order to connect these interfaces metallically to OSP
wiring.
Electrostatic Discharge (ESD)
Electrostatic Discharge (ESD) can damage equipment and impair electrical circuitry. ESD occurs when printed circuit
modules are improperly handled. It may result in module failure or intermittent problems.
