M5000 Series: User Guide
Issued June 20, 2007
Product Overview
VME Interface
The Tundra Universe IID PCI-to-VME Bridge is a PCI only component which provides VME
accesses.
Hardware configuration of the Universe IID is done entirely using micro switches.
RACE++ Interface
The Mercury PXB++ PCI-to-RACE++ Bridge is a PCI only component which provides RACE++
accesses.
Mezzanine Connector
The mezzanine connector provides access to a mezzanine board compatible with the previous
family of M5000 boards (via a spacer).
A set of two connectors provides accesses to one PCI bus (64-bit, 33MHz, 5V signaling) and
control signals.
Miscellaneous Functions
Board Interrupt Routing
The components on the M5000 board provide several interrupt sources and destinations. The
primary interrupt destination is the AMCC 440GX processor but interrupts may also be routed to
VME (through the Universe IID bridge) or RACEway (through the PXB++ bridge). If PMC site #1
is populated with a Processor PMC - Monarch card then the PMC site may become an interrupt
destination rather than a source. Configuration is made via dip-switches.
Board Reset
Board reset has a number of possible sources and destinations. The primary sources of reset are the
power-up reset controller and the reset button. Other sources are various software reset outputs
from the processor, VME reset, RACEway reset and the PMC modules.
