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.
