Table C-1 shows a system startup cycle and possible points of failure, 
up to and including the state in which the

 initialization 

program asserts the ONLINE LED. 

Table C-1.  LEDs and System Startup Status

1

None

Machine just turned on.

The VXIpc 800 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

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.

Resource Manager has been 
executed, indicating that the VXI 
software can now communicate with 
the VXI circuitry.

Resource Manager interface 
initialized successfully.
