When the 9153A or 9154A is first powered on the red Winchester disc drive on line LED and the yellow fault LED come on The yellow fault LED will come on as each of the tests in the power on sequence is ex ecuted and remain on until each test is finished In the case of a 9153A the red Winchester disc drive on line LED goes off and the red flexible disc drive LED comes on when the flexible disc part of the testing begins i A failure of a test in the power on sequence is signalled by the yellow fault LED blinking with specific pat terns as explained below If the yellow fault LED remains on continuously after the red Winchester disc drive on line LED and the flexible disc drive access LED have gone off something has failed that prevents the yellow fault LED from communicating the failure through its flashing codes for example processor or RAM failure Individual tests should then be run to attempt to isolate the problem Refer to the next subsection MANUAL EX ECUTION OF SELECTABLE SELFTESTS If the disc drive powers up and shows a flashing fault LED failure indication this indication will remain on until you successfully do an Initiate Diagnostic command an Initialize media command or again power up 8 2 TROUBLESHOOTING AND DIAGNOSTICS the drive and the drive passes If either the flexible or Winchester disc drive fails the power on test but the other is fully functional 9153A the good drive may be used No drive may be used i

LECTABLE SELFTESTS There are 8 selectable selftests available The list of tests follows after this explanation of procedure and the example of running the RAM test To run the tests the HP IB address switch should be set to the desired test number and the TEST test point located to the right of the flexible disc cable connector J4 must be shorted to ground GND 8 3 TROUBLESHOOTING AND DIAGNOSTICS NOTE Because the RAM test clears all parameters some of which are needed for other tests do not switch arbitrarily from test to test The RAM test should be performed first or be the last test which is run After each RAM test the unit goes through its power on sequence The following is an example of running the RAM test as the first test performed 1 Turn off the power to the unit 2 Select the RAM test 0 on the HP IB address switch and jumper the TEST test point to ground GND 3 Turn on power The unit then begins executing the RAM test The yellow fault LED remains on during the test When the test is completed the yellow fault LED should blink 5 times If the yellow fault LED remains on continously the test failed 4 Turn power off Select the next test using the HP IB address switch Do NOT select the RAM test 0 or 8 5 Turn on power The unit will begin the specified test Again when the test completes the yellow fault LED should blink 5 times If it doesn t the test failed The unit auto maticall
