Some PDUs have a remote monitoring capability that allows monitoring the
current consumption locally using an operator accessible meter and function
switch or remotely through a network connection. The monitor measures
consumption on each phase or inlet circuit attached to the PDU.
Alternately, you can use a voltmeter to verify the voltage of the available power.
Customers of Not-Racked Oracle FS Systems are responsible for engineering the
PDU connections.
Routing Power
Rack-ready systems require you to install the Oracle FS System components,
cords, and PDUs manually. For rack-ready systems, power cords are shipped
along with the components inside the shipping cartons.
Routing power in an Oracle FS System involves the following steps:
•
First, connect the power cords from the Oracle FS System components
•
(Drive Enclosures, Controllers, and Pilots) to the PDU outlets inside the
rack. The power cords are C13 to C14 left angled, single-phase power cords
and are usually rated at 110V and carry relatively low amperage.
Then, connect the Oracle FS System to the main power supply in the data
•
center by using power cables. The power cables routed into a rack to
supply power to the PDUs are often rated at 220V and are larger than the
internal power cords. These multi-phase power cables might be connected
to special 220V or 440v outlets or, sometimes, to an electrical bus.
Connecting the power cables is a two stage process with the following steps:
Connecting the Oracle FS System components (Drive Enclosures,
•
Controllers, and Pilots) to the PDU outlets: The Drive Enclosure to PDU
connections uses 90 degree power cords. The Controllers and Pilots have
straight connectors.
Connecting the Oracle FS System to the main power supply in the data
•
center: The main power supply connections use two power cables that are
shipped with Oracle racks and enter into the PDU about mid-rack.
Caution: Be sure to maintain reliable grounding of all the components mounted
in the rack.
