4.2.5 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.
4.2.6 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.)
8.Connect a voltmeter to output of CR3 and verify that the
4.2.7 VERIFY FAN AIR FLOW DIRECTION
1.Connect the power cables to a 110V AC source.
2.Connect the Plus lead of the Fan Cable to Bus Bar
3.Verify both power supplies are turned OFF. (Power Supply "A", is located on the left side at the bottom of the rack. Power Supply "B" is located on the right side at the bottom of the rack.)
4.Install both power supplies.
5.Turn Power Supply "A" on.
6.Verify that the Power On indicator is "ON" for Power Supply "A".
7.Verify that the air flow from the fan is to the outside.
4.2.8VERIFY VOLTAGES ON POWER DISTRI- BUTION CABLE
1.Verify voltages in Table
2.Turn Power Supply “A” OFF.
