4.1.3 TWO SHELF POWER SUPPLY
The Power Supply has a 115/230V AC 50/60 Hz input and 4 continuous duty outputs as follows:
+5V DC 24A.
The power supply can handle
4 separate +5V 2A connections.
2 separate
2 separate +12V connections.
2 separate
6 separate ground connections.
4.1.4 POWER SUPPLY REDUNDANT PLATE
The power supply drawer can be made redundant by the use of the redundant diode plate (PN 023-

4.1.5 VOLTAGE ADJUSTMENTS
See Figure
1.Connect a voltmeter to U1, pin 76 on an RVM (DO NOT use an extender card).
2.Adjust the +5V pot on the power supply for a reading of 5.1V.
3.If +5.1V cannot be obtained, change R84 to a 5.6k ohm 1/4W resistor.
4.1.6 REDUNDANT SUPPLY ADJUSTMENTS
See Figure
1.Remove the AC voltage to one of the supplies.
2.Connect a voltmeter to U1, pin 76 on an RVM (DO NOT use an extender card).
3.Adjust the +5V pot for a reading of 5.1V. (If +5.1V cannot be obtained, change R84 to a 5.1k ohm 1/4W resistor.)
4.Connect a voltmeter to output of CR3 and verify that the
5.Remove the AC voltage to the adjusted supply and connect AC voltage to the other power supply.
6.Connect a voltmeter to U1, pin 76 on an RVM (DO NOT use an extender card).
7.Adjust the +5V pot for a reading of 5.1V. (If +5.1V cannot be obtained, change R84 to a 5.1k ohm 1/4W resistor.)
