CAUTION: You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (–)to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site determines the color coding for the leads on the power cables that attach to the terminal studs on each power supply.

4.Remove the power cables from the DC power source.

5.Use a Phillips screwdriver to remove the clear plastic cover protecting the terminal block.

6.Within the terminal block, remove the screws that fasten the power cable lugs to the terminal block.

7.Carefully move the power cables out of the way.

8.Slide the ejector tab on the power supply faceplate to the right, and hold it in place to unlock the power supply.

10.Place one hand underneath the power supply to support it, and slide it completely out of the chassis.
