Equipment and Personal Safety Warnings
DC Power Source Warnings
Warning
Risk of electrical shock. After the power cables are connected to the chassis and the fuse
panel, the system is fully powered on; there is no power switch. To reduce the risk, always
remove the fuses in the fuse panel for all power sources to the chassis power zones (A1 and
A2, B1 and B2) before connecting the power cables to the chassis.
Warning
Risk of electrical shock. Improper grounding can result in an electrical shock. To reduce the
risk, this equipment must be connected to a protective ground in accordance with the
instructions provided in this guide.
Warning
Risk of electrical shock. There are mechanical and electrical shock hazards present
throughout the system if one or more of the cards is removed. To reduce the risk, only
qualified personnel are allowed to service the system.
Laser
Risk of severe damage to your eyes. All versions of the optical cards are Class 1 products,
which use lasers to convert electrical signals to optical signals that can damage your eyes. To
reduce the risk when handling these optical cards, keep the connectors covered until you are
ready to connect the fiber-optic cables. When you remove a cover, do not stare into the
connector or directly view the laser beam emerging from the connector.
Warning
Risk of personal injury. This equipment does not provide safety isolation between any port
that is connected to a digital network termination point and any other port to which terminal
equipment may be connected. To reduce the risk, disconnect the telecommunications network
cables before removing the card to which they are connected.
Warning
Risk of electrical shock. Because a system is fully powered on after all power connections are
made, it can cause shock if a power cable is disconnected from the chassis. To reduce the risk,
a readily accessible disconnect device, such as a fuse in a fuse panel, must be provided in the
fixed wiring for each DC power source. It must be suitable for the rated voltage and current
specified.
Warning
Risk of electrical shock. Safe operation of this equipment requires connection to a ground
point. To prevent possible injury from voltages on the telecommunications network,
disconnect all telecommunications network lines before disconnecting the unit from the
ground point.
Warning
Risk of electrical shock. The system uses DC power sources, which can cause severe injury.
To reduce the risk, the DC power sources must be installed only in restricted access areas
(dedicated equipment rooms, equipment closets, or the like) in accordance with Articles
110-17, 110-26, and 110-27 of the National Electric Code, ANSI/NFPA 70. Connect the
chassis to a –48 VDC source that is reliably connected to earth.
