MP Core I/O Connections

Each HP Integrity rx7620 Server can have up to two MP Core I/O board sets installed. This allows for two
partitions to be operating, or allows 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
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/off, access all
but two of the internal peripherals, and utilize other features of the system.
Connections to the MP/SCSI board include the following:
• DB25 Connector, by way of the M cable
This RS232 connector provides connections for a local console, external modem, and a UPS. The server
end of the M cable terminates in a DB25 connector. The opposite side of the cable terminates in three DB9
connectors labeled CONSOLE, UPS, and REMOTE.
• 10/100 Base-T LAN RJ45 connector (for LAN and Web Console access)
This LAN uses standby power and is active when AC is present and the front panel power switch is off.
• Internal LVD Ultra 160 SCSI channel for connections to internal mass storage
• Internal SE Ultra SCSI channel for connection to an internal removable media device.

LAN/SCSI Connections

The LAN/SCSI board is a PCI form factor card that provides the basic external I/O connectivity for the
system.
Connections to the LAN/SCSI board include the following:
• PCI-X to PCI-X bridge for multi-device compatibility
• Internal LVD Ultra 160 SCSI channel for connections to internal mass storage
• External LVD Ultra 160 SCSI channel connected to a 68-pin VHDCI connector
• 10/100/1000 Base-T LAN RJ45 connector.
The primary LAN interface is located on the LAN/SCSI board installed in the rightmost slot when viewing
the system from the back.

Management Processor Access

To access the Management Processor for the initial installation, the M cable must first be
NOTE
connected to the DB25 connector located on the primary MP/SCSI board. The primary
MP/SCSI board is located in the lower MP/SCSI board slot.
