TROUBLESHOOTING
Selftest
To implement the selftests available on the HP9114A controller, the following setup procedure
should be followed.
Setup:
-remove the battery pack and set it on its rear pannel adjacent to the unit as shown in
figure 4-2
-remove the 4 recessed Torx-head screws from the bottom of the unit.
-remove the top cover by pulling the cover straight up.
-remove the 4 Torx-head screws attaching the PCA to the bottom chassis
-Carefully lift the front edge of the PCA and remove the battery connector (J1)
-Position the PCA as shown in figure 4-2
-Connect on end of the supplied cable, (P/N 09114-61613), to the battery and the other
end to J1 on the PCA.
The selftest diagnostics are selected as follows.
1. Turn off the drive, and install a blank, formatted disc.
2. Configure the SVC TEST jumpers for the desired test. See figure 4-3
3. Turn on the drive, and set the START SVC jumper to the test enable position.
NOTE
The 9114 goes into STANDBY mode 30 seconds after power-up, or the last HP~IL command.
STANDBY mode enables only the RAM, the HP-IL chip, and the power-enable flip-flop.
To enable a test, the START SVC jumper must be installed within 30 seconds after the drive has
been turned on. Repeat this procedure for each test. Allow the power-on selftest to complete
before installing the START SVC jumper.
4. Reset the jumpers after testing.
There is no method of looping on a test.
The results of a successful test are displayed by the FAULT-LED blinking. A failure causes the
LED to stay on. Results are displayed for five seconds followed by a complete power-up sequence.
