Core I/O Connections - HP rx5670 Hardware Installation Manual

Core I/O Connections

Each hp server rx5670 contains one Core I/O board set, consisting of an MP/SCSI board and a LAN/SCSI
board. The MP/SCSI board is located in PCI Slot 1. The LAN/SCSI board is located in PCI Slot 3.
MP/SCSI Connections
The MP/SCSI board is required to update firmware, access the console, 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 via the M cable (part number A6144-63001).
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, REMOTE, and UPS.
• 10/100 Base-T LAN RJ45 connector (for LAN access to the management processor).
This LAN connection is available whenever the system is connected to a power source, even if the hp
server rx5670 main power switch is in the off position.
• Internal Ultra SCSI (Wide) channel for two internal mass storage devices.
• Internal Ultra SCSI (Narrow) channel for connection to internal removable media device.
LAN/SCSI Connections
The LAN/SCSI board provides the basic external I/O connectivity for the system.
Connections to the LAN/SCSI board include the following:
• Internal Ultra SCSI (Wide) channel for two internal mass storage devices.
• External LVD Ultra 160 SCSI channel connected to a 68-pin VHDCI connector
• 10/100/1000 Base-T LAN RJ45 connector (for LAN access to the system).
Management Processor
The management processor is an independent support system for the server. It provides a way for you to
connect to a server and perform administration or monitoring tasks for the server hardware.
The management processor controls power, reset, Transfer of Control (TOC) capabilities, provides console
access, displays and records system events, and can display detailed information about the various internal
subsystems. The management processor also provides a Virtual Front Panel which can be used to monitor the
front panel LEDs from a remote location.
The management processor is available whenever the system is connected to a power source, even if the hp
server rx5670 main power switch is in the off position.
Access to the management processor can be restricted by user accounts. User accounts can be password
protected and provide a specific level of access to the server and management processor commands.
Multiple users can interact with the management processor. However, all output is mirrored. The
management processor main menu permits all users to interact and mirrors output to all users. The console
permits one interactive user at a time and mirrors output to all users accessing those features.
