Power Supply

If the

power-on indicator is not on but the power

supply fan

is not turning, check the power cord for continuity

and

correct

installation.

 

If the power cord is not the problem, either the power supply is defective, or another component is defective causing the power supply to cut off. To verify the power supply is operating correctly, do the following:

1.Power-off the computer and disconnect the SelectaDock Docking System power cord.

2.Remove all internal devices, external devices, and the computer from the SelectaDock Docking System.

3.Undock the Base Model.

4.Remove the half-height bay frame (see “1050

Half-Height Bay Frame” on page 39).

5. Remove connectors.1/, .2/, .3/, .4/, and.5/ from the each device, tray, or card.

and 8 of.5/.the connector

Then check the power supply voltages on each

connector. If the

voltage

is not correct, replace the

power supply.

 

 

If any of the voltages is not correct, replace the power supply. If replacing the power supply does not correct the problem, replace the main card.
