MP Core I/O Connections

Each HP Integrity rx8620 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 allows for 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.
The core I/O board is used 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 Ultra3 (160MB/sec) 68-pin SCSI port for connection to external SCSI devices by a very 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.
• Three RS-232 connectors provide connections for a local console, remote console, and a UPS.
UPS port—A system serial port for connection to a UPS or another system application. The port is located
near the top of the core I/O card near the external SCSI connector when the card is installed in the server
chassis.
Remote console port—A remote serial port for connection to a modem. The port is located in the middle of
the three RS-232 connectors.
Local console port—A local serial port for connection to a terminal. The port is located at the bottom of the
core I/O card when the card is installed in the server chassis.
Internal connections for the core I/O board include the following:
• Three single ended (SE) internal SCSI buses for internal devices. These buses are routed to the system
board where they are cabled to a mass storage backplane.
