Oracle ZFS Storage Appliance Service Manual page 237

Motherboard: The motherboard is a FRU and includes CPU modules, slots for 18 DIMMs,
■
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 3.3V standby supply rail, which is available
whenever the system is receiving AC input power, even when the appliance 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 storage controller. It is directly
connected to the paddle board and to the motherboard through a bus bar and ribbon cable. It
also supports a top cover interlock kill switch.
Paddle Board: The paddle board is a FRU and serves as the interconnect between the
■
power distribution board and the fan power boards, hard drive backplane, and I/O board.
Fan Board: The fan boards are FRUs and carry power to the storage controller fan
■
modules. In addition, they contain fan module status LEDs and transfer I2C data for the fan
modules.
Disk Backplane: The hard drive backplane is a FRU and includes the connectors for the
■
hard disk drives, as well as the interconnect for the I/O board, Power and Locator buttons,
and system/component status LEDs. The storage controller has an eight-disk backplane.
Each drive has an LED indicator for Power/Activity, Fault, and OK-to-Remove (not
supported).
The following list contains the replaceable system boards for the 7320 storage controller.
