1 Introduction
Welcome to the I-Bus family of CompactPCI computer systems.
This manual provides information necessary to set up and maintain
the 0818D system.
The 0818D system is an 18-slot CompactPCI platform in an 8U
optimally cooled enclosure. Its backplane consists of two electrically
independent segments of PCI bus. Each segment accommodates a
system master SBC slot and 7 peripheral slots. The remaining two
slots are fabric slots. The system also contains four 200W DC input
hot-swap power supplies. The cooling system for the C08xx family
of enclosures incorporates three individually hot-swap blowers and a
hot-swap fan array in a redundant push-pull configuration.
The 0818D is a full hot-swap CompactPCI system that will
accommodate two-system master Single Board Computers (SBC’s)
such as the Intel based I-Bus 2801.
The reliability of the 0818D system is further enhanced when
powered by two alternative, independent power sources. The
utilization of these power sources is controlled by DC input power
modules. The input modules plug into the computer backplane from
the rear of the chassis. The two modules are identical and their
physical location determines which one is the preferred power
source. The module in slot A (upper) becomes the preferred input
and the module in slot B (lower) controls the secondary power input.
See Chapter 4 for more complete information on the dual power
input feature.
The 0818D has provision for the I-Bus Chassis Management
Controller (CMC). The CMC Board functions to monitor and control
the system environment of a custom cPCI enclosure. It operates as
an independent Chassis Management Controller manageable
through its RS232 port by an external device. See Chapter 6 for a
discussion of the CMC as it relates to the 0818D. Refer to the CMC
Programmer’s Guide for further instructions and specifications.
