MP Core I/O Connections
Each hp rp7405/rp7410 can have up to two MP Core I/O board sets installed. This allows for two partitions to
be operating, or allows for 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 & 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 one of the internal peripherals, and utilize other features of the system.
Connections to the MP/SCSI board include the following:
DB25 Connector; via 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 3 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 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
NOTE In order to access the Management Processor for the initial installation, the M cable must first
be 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.
