LEDs and System Startup Cycle
Table C-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 SYSFAIL or FAILED 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-700 jumper settings are correct.
4. Make sure that the VXIpc-700 is seated properly in the mainframe.
5. Power on the mainframe and observe whether the SYSFAIL and
FAILED LEDs become unlit some time before the operating system
boots.
Table C-1. LEDs and System Startup Status
Step LEDs Lit Status
Possible Problem If
VXIpc-700 Fails
1 None Machine just turned on. The VXIpc-700 is not receiving
power.
2 FAILED,
SYSFAIL Now asserting SYSFAIL because
VXIbus interface has not been
initialized yet. Power-on self configuration (POSC)
cannot execute because of problems
with system reset or because the
POSCEN switch is incorrectly
configured.
3 FAILED,
TEST VXI interface is being initialized by
MITE power-on self configuration
(POSC) circuitry. POSC has stalled.
4 TEST POSC circuitry has initialized VXI
interface, setting PASSED and
DONE bits. POSC stalled before clearing the
TEST LED.
5 None POSC cycles are complete. VXI port
is ready to respond to Resource
Manager inquiries. POSC completed successfully;
however, the Resource Manager
either hung or was not executed.
6 ONLINE Resource Manager has been
executed, indicating that the VXI
software can now communicate with
the VXI circuitry. Resource Manager interface
initialized successfully.
