VME Bus Activity (default)
Red: Universe II asserted VME SYSFAIL signal to the VMEbus
Green: Universe II accesses the VMEbus as master
OFF: No SYSFAIL signal asserted and no Universe PCI−to−VME bridge activity
Ethernet Activity
Depending on LED control register 3 settings, the LED indicates activity of Ethernet
interfaces 1 to 4 or a combination of these
User−LED Mode
Via LED control register 3, the LED can be programmed to be OFF, green or red.

This key has two functions. When pressed longer than 0.5 s, a reset is generated which is
indicated by the LED 1 shining red. When the key is pressed for a period shorther than 0.5
s, an abort is generated which is indicated by the LED 1 shining weak red.

Note:

An abort should only be triggered if an application under Solaris or OpenBoot
hangs. Do not trigger an abort to enter OpenBoot or to bypass the diagnostic routine
during power up. After triggering an abort , the board is in diagnostic mode and the
OpenBoot ok prompt appears. In this mode, you can diagnose what caused the
program to hang. However, the board is not fully initialized and therefore is not fully
functional. To regain the full functionality, you need to trigger a reset.
