NOTE:
The proper release of software must be installed for this test
to work. If software has not been installed, the letter "P" will
be displayed in the 7-segment FE ID display. If the software
in the SYSCTL is incompatible with the software in the
OHCTL or with the shelf configuration, the letter "d" or "C"
will be displayed in the 7-segment FE ID display. If the
proper release of software has not been installed or if the
SYSCTL and OHCTL have incompatible software, refer the
problem to the organization that installed the shelf.
Depress and hold the ACO pushbutton on the User Panel. Verify
that all User Panel and circuit pack LEDs and the SYSCTL
display light. Verify proper version of software is installed.
