• SCSI 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 external mass storage devices that you can connect
to Channel B of the core I/O SCSI HBA. External connections to Channel B of the SCSI HBA
controller are only supported in simplex configuration, when the internal cable between the
SCSI backplane and the SCSI HBA card is disconnected. If the server is converted to the
duplex configuration, you cannot connect external SCSI devices to Channel B of the SCSI
HBA.
• LAN Connection
— The LAN board provides the basic external I/O connectivity for the system.
— Connections to the LAN card include one or two 10/100/1000 Base-T LAN RJ45
connectors.
— New cards might be available for use in the server. See the available cards on the HP
website at http://hp.com.
