Request the Customer release the System and the RA81 Drive. 2. Depress the "A" and the "B" Port Switches on the Operator Control Panel. ( on the front of the Drive) to the "OUT" position. 3. Spin the Drive down by depressing the "RUN/STOP" Switch on the Operator Control Panel ( on the front of the Drive) to the "OUT" position. 4. Open the back Door to the Cabinet. 5. ************************************************************** * CAUTION * * Before proceeding, turn off the AC Circuit Breaker at the * * rear of the Drive. * ************************************************************** 6. If the Drive is fixed mounted (top Drive), proceed to rework step 11. _ _ _ _ _ _ _ | FCO RA81X-I015 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 3 OF 13 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ 7. Pull out the Cabinet Stabilizer, see figure 1. *************************************************** * CAUTION * * Never slide a drive out of the cabinet without * * first extending the cabinet stabilizer. * *************************************************** Figure 1 _ _ _ _ _ _ _ | FCO RA81X-I015 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 4 OF 13 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ 8. Remove the Screw holding the back of the Disk Drive to the Electrostatic Discharge Bracket ( ESD ), see figure 2. Figure 2 _ _ _ _ _ _ _ | FCO RA81X-I015 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 5 OF 13 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ 9. Slowly pull the Drive out on it's Slides until it locks into place. 10. Push up on the Slide Lock Arm "A" and further extend the Drive to the limits of the Slides, see figure 3. Figure 3 _ _ _ _ _ _ _ | FCO RA81X-I015 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 6 OF 13 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ 11. Unlock the Chassis release Latch, see figure 4. Figure 4 _ _ _ _ _ _ _ | FCO RA81X-I015 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 7 OF 13 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ 12. Lift the Drive Chassis to a completely raised position, see figure 5. 13. Before proceeding ensure that the Velostat Anti-static Kit ( P/N - 29-11762-00 ) is being properly utilized during any handling of the Read/Write module. 14. Remove the Read/Write Module P/N 54-15253, see figure 5. Figure 5 _ _ _ _ _ _ _ | FCO RA81X-I015 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 8 OF 13 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ 15. Remove C29 ( 0.01 Mfd, 50v capacitor),see figure 6. 16. Install C29 (0.1 Mfd 50v Capacitor P/N 10-13466-22) supplied in the FCO kit, see figure 6. 17. Remove C35 ( 0.01 Mfd, 50v capacitor), see figure 6. 18. Install C35 (0.1 Mfd 50v Capacitor P/N 10-13466-22) supplied in the FCO kit, see figure 6. Figure 6 _ _ _ _ _ _ _ | FCO RA81X-I015 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 9 OF 13 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ 19. When the above rework is complete mark the module Part Rev "J2". 20. Re-Install the Reworked Read/Write Module back into the Drive. 21. Lower the Drive Chassis until the Chassis Latch engages. 22. If the Drive is fixed mount ( top Drive ) proceed to rework step 25. _ _ _ _ _ _ _ | FCO RA81X-I015 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 10 OF 13 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ 23. Push in on the Slide Arm "A" and slowly slide the Drive back into the Cabinet, see figure 7. Figure 7 _ _ _ _ _ _ _ | FCO RA81X-I015 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 11 OF 13 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ 24. ************************************************* * CAUTION * * Re-install the screw holding the back of the * * drive to the electrostatic discharge bracket * * (See Figure 8). * ************************************************* Figure 8 _ _ _ _ _ _ _ | FCO RA81X-I015 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 12 OF 13 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ 25. Raise the Drive circuit breaker ( at the rear of the Drive) up to the "ON" position. 26. Close the back Door of the Cabinet. 27. Depress the "WRITE/PROT" Switch on the Operator Control Panel to the "OUT" position. 28. Spin the Drive "UP" by pressing the RUN/STOP switch on the Operator Control Panel to the "IN" position. 29. Observe the "READY" lamp on the Operator Control Panel and verify that it illuminates after about "60" seconds. 30. Observe the "READY" lamp on the Operator Control Panel and verify the following: A) The READY Lamp should extinguish ( go out) approximately every 30 seconds. B) The READY Lamp should re-illuminate ( go on ) approximately every 30 seconds. This process allows the Drive Internal "Idle" Diagnostics to recycle as long as the "Port Switches and Write Protect switch are released. 31. Verify that the Fault Lamp does not illuminate during several cycles of the process described in step 30 above. 32. Press the "A" and /or "B" port switches on the Operator Control Panel to the "IN" position. 33. Run EVRLA (VAX Diagnostic or CZUDA (PDP-11 Diagnostic) or HSC ILEXER to insure the proper operation of the Drive. 34. Return the Drive and the System to the Customer. 35. Log the FCO activity in the Site Management Guide. 36. Report LARS data as per example on page 13. _ _ _ _ _ _ _ | FCO RA81X-I015 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 13 OF 13 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ LARS USA & GIA EUROPE Activity Contract and warranty W Y Non Contract/Non Warranty F F DEC Option RA81X RA81X Type of Call M M Action Taken D I Fail Area-Module-FCO-Comments RA81X-I015 RA81X-I015 Material Used EQ-01472-01 EQ-01472-01 \^ RA81X \\RA81X \\BROWN \\1987 \\APR \\FCO_DOCS
