7120 Internal Boards
The chassis has the following boards installed.
Note - Field-replaceable units (FRU) should only be replaced by trained Oracle service
technicians.
■
PCIe Risers: Each riser supports two PCIe cards that are customer-replaceable. There are
two risers per system, each attached to the rear of the motherboard.
■
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 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 storage controller. It is directly
connected to the connector break out board and to the motherboard through a bus bar and
ribbon cable. It also supports a top cover interlock kill switch. The power supplies connect
directly to the power distribution board.
■
Connector Break Out Board: The connector break out board is FRU and serves as the
interconnect between the power distribution board and the fan power boards, storage drive
backplane, and I/O board. It also contains the top-cover interlock "kill" switch.
