Core I/O Connections
Each hp Integrity rx4640 Server core I/O includes:
• Two USB ports
• One UDMA-100 IDE port (40 pin IDE connector)
• SVGA controller (DE15S connector)
• One common server management (CSM)
— One 10/100 LAN-RJ45
— Three serial ports
• SCSI host bus adapter (HBA)
— The SCSI HBA board is required 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 may want to connect to channel B of
your core I/O SCSI HBA. External connections to channel B of your 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 you convert your system to duplex configuration (see “Converting SCSI
From Simplex to Duplex” on page 65), you may not 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 10/100/1000 Base-T LAN RJ45 connector.
Management Processor (MP)
The management processor is an independent support system for the server. It provides a way for you to connect to your HP
Server and perform administration or monitoring tasks for the server hardware.
The management processor controls power, reset, transfer of control (TOC) capabilities, provides console access, displays and
records system events, and can display detailed information about the various internal subsystems. The management processor
also provides a virtual front panel that can be used to monitor the front panel LEDs from a remote location.
The management processor is available whenever the system is connected to a power source, even if the hp Integrity rx4640
Server main power switch is in the off position.
Access to the management processor can be restricted by user accounts. User accounts can be password-protected and provide
a specific level of access to the server and management processor commands.
Multiple users can interact with the management processor. From the MP Main Menu users can select any of the following
options: enter management processor command mode, enter console, view event logs, view console history, display virtual
front panel, enter console session, or connect to another management processor. Multiple users can select different options
from the MP Main Menu at the same time. However, management processor command mode and console mode are mirrored.
The MP allows only one user at a time to have write access to the shared console.
