(Turn the power switch to * * the "off" position, and unplug the power cord from the outlet).* * Use Care when handling the drive. Be sure to wear an * * antistatic wrist strap while working on equipment. * ******************************************************************* 1. Shut off the power to the expansion box and unplug the expansion box power cord from the outlet. 2. Unscrew the four cover screws and remove the expansion box cover. (See Figure 1) 3. Remove the three screws that hold the shield to the main chassis and lift the shield up and off. (See Figure 2) 4. Remove the three drive mounting screws. (See Figure 3) 5. Remove the SCSI switch cable from the SCSI switch board. (See Figure 4) 6. Slide the drive halfway out of the expansion box and disconnect the power cable, data cable, and SCSI switch cable from the back of the drive. Then remove the drive. (See Figure 5) 7. Once the drive is free from the expansion box, remove the mounting bracket screws and the mounting brackets. (See Figure 6) 8. Install the mounting brackets on the new drive contained in EQ Kit# EQ-01581-02 and reverse this procedure. 9. Update the drive revision level with the barcode labels supplied. 10. Test the RZ55 drive by using the system diagnostics. Perform the Power-up test and Self-test diagnostics. +-------------+ | FCO RZ55-I001 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 3 OF 6 | | | | | | | | | +-------------+ | _______________________________|_________________________________________ FIGURE 1 +-------------+ | FCO RZ55-I001 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 4 OF 6 | | | | | | | | | +-------------+ | _______________________________|_________________________________________ FIGURE 2 FIGURE 3 +-------------+ | FCO RZ55-I001 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 5 OF 6 | | | | | | | | | +-------------+ | _______________________________|_________________________________________ FIGURE 4 FIGURE 5 +-------------+ | FCO RZ55-I001 | | | | | | | | | |d|i|g|i|t|a|l| | PAGE 6 OF 6 | | | | | | | | | +-------------+ | _______________________________|_________________________________________ FIGURE 6 \^ RZ55 \\RZ55 \\RZ55-I001 \\WILBON \\1990 \\JUL \\FCO_DOCS
