Installing the Hardware
Warning!
Risk of electrical shock. 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.
Warning!
Risk of electrical shock. 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. The system is
fully powered on after all power connections are made, it can cause shock if a
power cable is disconnected from the chassis.
Warning!
Risk of electrical shock. Disconnect all telecommunications network lines
before disconnecting the unit from the ground point. Safe operation of this
equipment requires connection to a ground point.
Warning!
Risk of electrical shock. This equipment uses –48 VDC power, which can
