Connecting the Cables
This section describes the cables to connect to power the server and to provide LAN connectivity for the
server.

AC Input Power

The HP 9000 rp4410 and rp4440 servers come with one or two power supplies installed. A power supply
includes an ac input connector which is rated for 200 to 240 VAC at 13 amps. If two power supplies are
installed, both power supplies must be connected separately to an ac power source.

Core I/O Connections

Each HP 9000 rp4410 and rp4440 server core I/O includes:
• Two USB ports
• One iLO MP
— One 10/100 LAN-RJ45.
— Three serial ports.
• SCSI Host Bus Adapter (HBA)
— The SCSI HBA board is used to attach SCSI external mass storage to the system.
— Connections to the SCSI board include the external SCSI channels for external mass storage devices.
CAUTION Some restrictions apply to the mass storage devices that can be connected to the core I/O
SCSI HBA. External connections to the SCSI HBA core I/O controller are only supported
when the internal cable between the SCSI backplane and the SCSI HBA core I/O card is
disconnected. The server is shipped in simplex configuration which supports external
devices. If you convert the server to duplex configuration, you cannot install external SCSI
devices.
• LAN Connection
— The LAN board provides the basic external I/O connectivity for the system.
— Connections to the LAN card include one 10/100/1000 Base-T LAN RJ45 connector.
Ensure that the system is powered off and all power sources have been disconnected
WARNING
from the server before attempting the following procedures.
Voltage is present at various locations within the server whenever an ac power
source is connected. This voltage is present even when the main power switch is in
the off position.
Failure to observe this warning can result in personal injury or damage to
equipment.
