Disconnect the cables labeled "POWER1" and "POWER2" from the powersupply paralleling board (PSPB) (see Figure 9), and remove them from the system. 4. Disconnect the 68-pin Ultra2/low voltage differential (LVD) small computer system interface (SCSI) cable from the SCSI backplane connector labeled "SCSI A," and remove it from the system. 5. Disconnect the 50-pin Ultra/Narrow SCSI cable from the CD-ROM drive, and remove it from the system. To remove the system board from the chassis, perform the following steps: 1. Remove the six screws that hold the system board tray to the bottom of the chassis (three screws on each side). 2. Lift up slightly on the system board tray. 3.
