7420 Electrical Specifications
The following list shows the electrical specifications for 7420 controllers.
Note -
The power dissipation numbers listed are the maximum rated for the power supply and
are not a rating of the actual power consumption of the appliance.
Input
■
Nominal frequencies: 50/60Hz
■
AC operating range: 100-127 VAC for 2 CPUs and 200-240 VAC for 2 or 4 CPUs
■
Maximum current AC RMS: 12A @ 100 VAC / 12A @ 200 VAC
Power Dissipation
■
Max power consumption: 1800 W
■
Max heat output: 6143 BTU/hr
■
Volt-Ampere rating: 1837 VA @ 240 VAC, 0.98 P.F.
7420 Internal Boards
The 7420 controller chassis has the following boards installed. Field-replaceable units (FRUs)
should only be replaced by trained Oracle service technicians.
■
Motherboard:
The motherboard is a FRU and includes CPU modules, slots for eight
DIMM risers, memory control subsystems, and the service processor (SP) subsystem.
The SP subsystem controls the host power and monitors host system events (power and
environmental). The SP controller draws power from the host's 3.3V standby supply rail,
which is available whenever the system is receiving AC input power, even when the system
is turned off.
■
Power Distribution Board:
The power distribution board is a FRU and distributes main
12V power from the power supplies to the rest of the system. It is directly connected to
the Vertical PDB card, and to the motherboard through a bus bar and ribbon cable. It also
supports a top cover interlock ("kill") switch. In the storage controller, the power supplies
connect to the power supply backplane which connects to the power distribution board.
