Power Supply
Figure 11, Power supply assembly top view
The device is equipped with a switching power supply that satisfies all power
requirements of the system. The supply provides five DC voltage levels, which
can be measured on the backplane card at P507. Refer to Table 3 on page 34
for each pin definition.
There is only one adjustment on the power supply and it is for the 5 volt supply.
Voltage levels must be set with a load applied; therefore, it is recommended
that the supply is adjusted only after installation into the device. The 5 volt
supply voltage is pre-adjusted at the supplier and should require only minor
calibration. All outputs are protected against overload and short circuit.
Recovery is automatic when the fault is removed.
The supply is cooled by a self-mounted fan; this improves the stability of the
voltage levels.
