The use of the VELOSTAT * * kit is essential to prevent damage which may not be * * noticed immediately. * ********************************************************** INSTALLATION PROCEDURE: 1. Perform normal system shutdown procedures. 2. Power down system. 3. Remove interface cable from M7546 module, P1. 4. Remove module M7546 from backplane. 5. Using figure 1 as a reference, replace the following components with parts supplied. A. Remove chip from position E3, replace with chip marked 23-065L1-00. B. Remove chip from position E28, replace with chip marked 23-249E5-00. C. Remove chip from position E29, replace with chip marked 23-248E5-00. NOTE: This ROM replacement brings the microcode (FW) to REV 4, and the hardware (HW) REV to 6. 6. Using figure 1 as a reference, change switch setting of component E38 to: bits 2 and 3 on, all others off. This changes the hardware REV register to 6. 7. Mark the hande REV F1. 8. Reinstall module in backplane and replug cable. Observe proper cable orientation. 9. Power up system. 10. Observe for normal power up onboard diagnostic completion. Refer to paragraph 4.4.1.7 and 4.4.1.8, page 4-12 in the TK50 Tape Drive Subsystem Manual, # EK-0TK50-TM. 11. Return system to customer. 12. Complete LARS form as per Figure 2. _ _ _ _ _ _ _ | FCO TQK50-I001 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 3 OF 4 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ Figure 1 _ _ _ _ _ _ _ | FCO TQK50-I001 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 4 OF 4 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ LARS Activity DEC Type Action FCO # Material Option of Taken Comments Used Call ****************************************************************************** For Contract and Warrant Customers U.S. and G.I.A.
