Locatlon Of Pertinent Components On Inp Pca - HP 3000 Series Installation And Service Manual

Ma intenance
The other way of initiating the self test is to press the RESTART
switch. (Refer to the Installation Verification instructions in
Section II for details on this method of initiating the self
test. Also, the exact location of the INP within the card cage
can be obtained from the installation notation in the configura-
tion section of the System Support Log.)
The self test checks most of the circuitry of the INP PCA board.
If, upon completion of the self test, the self-test LED indicator
lights (figure 5-1) are displaying 0 and 7 (only the two lights
at each end are lighted), there is no detectable hardware mal-
function within the INP PCA board. If any other combination of
lights is being displayed or if you still suspect a malfunction
beyond the physical limits of the PCA boards, call your Hewlett-
Packard Customer Engineer (CE).
