Mp Core I/O Connections; Setting Up The Customer Engineer Tool (Pc) - HP Integrity rx8640 Installation Manual

Cabling and Powering On the Server

MP Core I/O Connections

Each HP server has at least one core I/O card installed. Each core I/O card has a management processor (MP).
If two core I/O cards are installed, this allows for two partitions to be configured or enables core I/O
redundancy in a single partition configuration. Each core I/O card is oriented vertically and accessed from the
back of the server.
Use the core I/O board to update firmware, access the console, turn partition power on and off, and utilize
other features of the system.
External connections to the core I/O board include the following:
• One Ultra 320 (320 MB/sec) 68-pin SCSI port for connection to external SCSI devices by a high-density
cable interconnect (VHDCI) connector.
• One RJ-45 style 10Base-T/100Base-T/1000Base-T system LAN connector. This LAN uses standby power
and is active when AC is present and the front panel power switch is OFF.
• One RJ-45 style 10Base-T/100Base-T MP LAN connector. This LAN uses standby power and is active
when AC is present and the front panel power switch is OFF. This LAN is also active when the front
power switch is ON.
• One DB-9 RS-232 connector which provides local console.
Internal connections for the core I/O board include the following:
• Two low voltage differential (LVD) internal SCSI buses for internal drives
• One single-ended (SE) internal SCSI bus for internal media.

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
• Setting LAN IP addresses
• Shutting down cell board power
Establish communication with the MP by connecting the CE Tool to the local RS-232 port on the core I/O card.
Setting CE Tool Parameters
After powering on the CE Tool, ensure that the communications settings are as follows:
• 8/none (parity)
• 9600 baud
• None (Receive)
• None (Transmit)
