Additionaly, when the MVME5100 is configured as a System Controller (SCON), a SYSRESET#
signal may be generated by toggling the ABT/RST switch to RST, or by a power-up reset, or by
a watchdog timeout, or by a control bit in the Miscellaneous Control Register (MISC_CTL) in the
Universe ASIC.
Note: SYSRESET# remains asserted for at least 200 ms, as required by the VMEbus
specification.
2.2.2 Status Indicators
There are two Light-Emitting Diode (LED) status indicators located on the MVME5100 front
panel. They are labeled BFL and CPU.
2.2.2.1 RST Indicator (DS1)
The yellow BFL LED indicates board failure; this indicator is also illuminated during reset as an
LED test. The BFL is set if the MODFAIL Register or FUSE Register is set. Refer to the MVME5100
Single Board Computer Programmer’s Reference Guide (V5100A/PG) for information on these
registers.
2.2.2.2 CPU Indicator (DS2)
The green CPU LED indicates CPU activity.
2.2.3 Connectors
There are three connectors on the front panel of the MVME5100. Two are bottom-labeled
10/100BASE T and one is labeled DEBUG.
2.2.3.1 10/100BASE T Ports
The two RJ-45 ports labeled 10/100BASE T provide the 10BASE T/100BASE TX Ethernet LAN
interface. These connectors are top-labeled with the designation LAN1 and LAN2.
