5.8.4. Disk/Tape Module (Model 31) DC Voltage Test:
1. Remove the CPU Module from the top of the Disk/Tape
·Module.
2. DC output voltages are checked at the SMD input power
cable power connector P2 located on the rear of the SMD
(Figure 5-7).
3. SMD Voltage adjustments on the power supply (Figure 5-
8) are for +5VDC (+5VDC ADJ), -12VDC (-12VDC ADJ), and
+24VDC(+24VDC ADJ). (See Figure 5-8 for locations.)
