This chapter provides operating instructions for the MVME5100 Single Board Computer. It
includes necessary information about powering up the system along with the functionality of the
switches, status indicators and I/O ports on the front panels of the board.

The on-board Universe ASIC includes both a global and a local reset driver. When the ASIC
operates as the System Controller, the reset driver provides a global system reset by asserting
the SYSRESET# signal.
Additionaly, when the MVME5100 is configured as a System Controller (SCON), a
SYSRESET# signal may be generated by toggling the
up reset, or by a watchdog timeout, or by a control bit in the Miscellaneous Control Register
(MISC_CTL) in the Universe ASIC.
