Battery Unit
1.12 Interface Module M9715–AA (Used in BA430)
The M9715–AA interface module is located on the extreme right, next to
the power supply (backplane slot 0). The M9715 I/O provides terminator
power for both the DSSI and SCSI busses. Slot 0 is a dedicated dual C/D
backplane slot on the Q22- bus (J24).
1.13 Power Supply (H7874)
Both the BA430 and BA440 enclosures contain a modular H7874 power
supply (Table 1–3). The power supply plugs into the backplane through
two connectors. The H7874 power supply delivers the following maximum
current:
22 amperes at +12.1 Vdc
60 amperes at +5 Vdc
7 amperes at +3.4 Vdc
4 amperes at -12.1 Vdc
