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 M7547 module, P1. 4. Remove module M7547 from backplane. 5. Using figure 1 as a reference, replace the following components with parts supplied. A. Remove chip from position E48, replace with chip marked 23-250E5-00. B. Remove chip from position E49, replace with chip marked 23-251E5-00. ************************************************************* * NOTE * * * * This ROM replacement brings the microcode (FW) to REV 4. * * * ************************************************************* 6. Using figure 1 as a reference, change switch setting of component E5 to: bits 1 and 2 on, all others off. This changes the hardware REV register to 3. 7. Mark the handle REV C2. 8. Reinstall module in backplane and replug cable. Observe proper cable orientation. 9. Power up system. _ _ _ _ _ _ _ | FCO TUK50-I001 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 3 OF 5 |_|_|_|_|_|_|_| | | _______________________________|_________________________________________ 10.
