Commercial Systems Division The Core I/O card is a component installed in the N-Class and A-Class systems that contains all the I/O components necessary to configure a bootable system (not including disks and tapes drives and terminals). The core I/O card contains the following functions
Guardian Service Processor
The Guardian Service Processor (GSP) provides the functionality required for basic console operations to control the hardware before the OS is booted and to provide the connectivity to manage the system. The functions supported by the GSP are similar in nature to those provided by the Access Port (AP) interface on previous platforms. For example, the functions display selftest chassis codes, execute boot commands, determine installed hardware, etc. For more information on the GSP functions see System Startup, Configuaration, and Shutdown Reference Manual Appendix H and the article in this chapter, MPE/iX A-Class and N-Class Console.
Serial ports
The three external serial ports perform the same general purposes as on previous platforms.
Local console provides direct connect for a C1099A terminal.
Remote console port provides a modem capable port for remote support access. It is not recommended for this port to be used for general user dial-in access.
The third serial port is intended for use to connect to a UPS. The console driver will not allow a user to logon to this port. This behavior is the same as on previous platforms.
The GSP LAN/Console Port
This port provides a 10Base-TX connection into the GSP. When a logon is established to the GSP, that logon can be used to perform almost all console functions that are available on the local and remote console ports such as startup and shutdown of the system.
SCSI Connections
The N-Class Core I/O card contains embedded versions of both an A5159A (Dual Port) and an A5149A (Single Port) cards. The A5159A portion of the Core I/O card supports the two internal system disk slots The A5149A portion of the Core I/O card presents a single LVD/SE bus for the connection of device(s) external to the system. The A-Class Core I/O card contains embedded versions of both the A5159A (Dual Port) and a A5150A (Dual Port) cards. The system uses one port from each card to support a single internal disk and presents the other SCSI bus to allow the connection of external SCSI peripherals. Path 0/0/1/0 (from the A5159A) is provided with a VHDCI 68-pin LVD/SE connector. Path 0/0/2/0 (from the A5150A) is provided with a special HD 50-pin SE connector: this connector only supports an 8-bit data path so only "narrow" SCSI devices such as the DDS-3 Tapes may be connected. See the section titled PCI-SCSI Device Adapter Cards on HP e3000 N-Class and A-Class Systems for details on configuring and using these SCSI ports.
Multi-function Core I/O card LAN port is now supported
The 10/100Base-TX LAN port on the multi-function Core I/O card in the N-Class and A-Class HP e3000 systems is now supported, beginning in Release 7.0 Express-1. The port will behave exactly like ports on PCI 100Base-T add-on adapters (A5230A), although a different set of LED's is provided. Labels on the LED's on the Core I/O card ("Link", "100", etc.) are self-explanatory.Because the Core I/O LAN port is now supported, new N-Class and A-Class systems will no longer be shipped with a no-extra-cost add-on 10/100Base-TX card. Add-on adapters may still be purchased separately.Please see the PCI 100Base-T Installation and Service Guide (32650-90904) for more information on connecting your system to a LAN using either the Core I/O card LAN port or PCI 100Base-T add-on adapter.
