Installation Cabling and Power Up 4. Use the supplied Velcro straps to attach the cords to the anchor. See Figure 2-26, "Line Cord Anchor and Velcro Straps," Figure 2-26 Line Cord Anchor and Velcro Straps Velcro Straps MP Core I/O Connections Each HP 9000 rp8420 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.

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. 60 Chapter 2

MP Core I/O Connections
Each HP 9000 rp8420 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.
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.
