LEDs and System Startup Cycle
Table B-1 shows a system startup cycle and possible points of failure, up to
and including the state in which the
ONLINE LED is asserted.
If either the SYSF or FAIL LED remains lit, perform the following steps:
1. Power off the mainframe.
2. Remove all other modules from the mainframe.
3. Make sure that the VXIpc 870 Series switch and jumper settings are
correct.
4. Make sure that the VXIpc 870 Series is seated properly in the
mainframe.
5. Power on the mainframe and observe whether the SYSF and FAIL
LEDs become unlit some time before the operating system boots.
