Cabling and Power Up

Core I/O Connections

Each server can have up to two core I/O board sets installed which allows for two partitions to operate, or MP
core I/O redundancy in a single or dual partition configuration. Each 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 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
and LAN/SCSI boards, only the top two internal disks can be accessed.
MP/SCSI I/O Connections
The MP/SCSI board is required to update firmware, access the console, turn partition power on or off, access
one of the HDDs and one of the removable media devices, and utilize other features of the system. For
systems running a single partition, one MP/SCSI board is required. A second MP/SCSI board is required for a
dual-partition configuration, or if you want to enable primary or secondary MP failover for the server.
Connections to the MP/SCSI board include the following:
• DB9 connector for Local Console
• 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 320 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
• Two LVD Ultra 320 SCSI channel controllers: one for internal connection to one of the HDD devices, and
the other is available for connection to an external device
• Two 10/100/1000 Base-T LAN RJ45 connectors
The primary LAN interface is located on the LAN/SCSI board installed in the right-most slot when viewing
the system from the back.
Management Processor Access
NOTE The primary MP/SCSI board is located in the lower MP/SCSI board slot.

Setting Up the Customer Engineer Tool (PC)

The CE Tool is usually a laptop. It allows communication with the Management Processor (MP) in the server.
The MP monitors the activity of either a one-partition or a multiple-partition configuration.
During installation, communicating with the MP enables such tasks as:
• Verifying that the components are present and installed correctly
