3.2.1
Reset Switch
The MVME2502 has a single push button switch that has both the abort and the reset
functions. Pressing the switch for less than three seconds generates an abort interrupt if
there is firmware that will read the GPIO2 (0xffdf0095) interrupt register. U-boot does not
implement any interrupts and also does not detect the interrupt or display anything when
the button is pressed.
Holding it down for more than three seconds will generate a hard reset. The VME
SYSRESET is generated if the MVME2502 is the VMEbus system controller.
3.3
LEDs
The MVME2502 utilize light emitting diodes (LEDs) to provide a visible status indicator on
the front panel. These LEDs show power failures, power up states, Ethernet link/speed,
Ethernet activity, SATA link and activity and PCIe valid lane status. There are few user
configurable LEDs. Each LED description is necessary for troubleshooting and debugging.
