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.
