Power Distribution Panel
A power distribution panel (PDP) may be installed in a Model S00 rack to distribute
-48 V DC power to the drawers and devices in the rack. The power distribution
panel provides circuit breakers that protect each drawer in the rack from excess
current and function as DC power switches for switching off power to the devices
and drawers before servicing.
Note: The power distribution panel configurations shown in this manual are for
example purposes only. The actual power distribution panel installed in the
rack you are servicing may vary in terms of circuit breaker ratings, circuit
breaker configurations, and connections to the customer's power source.
The PDP contains a connection location on the rear cover for attaching a customer
supplied circuit breaker alarm. This alarm indicates when any circuit breaker is
switched to the off position.
The circuit breaker switch is on when it is in the up position, and the switch is off
when it is in the down position.
