MP Core I/O Connections

Each HP 9000 rp7420 server can have up to two MP core I/O board sets installed. Which allows
two partitions to operate, or MP core I/O redundancy in a single partition configuration. Each
MP core I/O board set consists of two boards: the MP/SCSI board and the LAN/SCSI board. The
MP/SCSI board is oriented vertically and accessed from the back of the server. The LAN/SCSI is
accessed from the PCI/PCI-X expansion card bay. Only the primary MP core I/O board set
(MP/SCSI slot 1 and LAN/SCSI slot 8, chassis 1) is required for a single partition implementation.
The secondary MP/SCSI board is not necessary for full operation. However, without the secondary
MP/SCSI board, only two internal disks can be accessed.

MP/SCSI Connections

The MP/SCSI board is required to update firmware, access the console, turn partition power on
or off, access all but two of the internal peripherals, and use other features of the server.
Connections to the MP/SCSI board include the following:
There is a risk of shock hazard while testing primary power. Use properly
Do not set site AC circuit breakers serving the processor cabinets to On before
