Warning Do not mix AC-input and DC-input power supply units in the same SCE 2000 platform.
To install a new power supply into a SCE 2000 platform, complete the following steps:
Step 1 Grasp the power supply unit handle with one hand and place your other hand underneath the
power supply for support.
Step 2 Fit the groove in the side of the new power supply module into the guide in the chassis.
Step 3 Gently, but firmly, slide the module into the chassis until its faceplate is flush with the chassis rear
panel.
Warning When inserting a power supply into the SCE 2000 platform, do not use unnecessary force; slamming
the power supply into the chassis can damage the connectors on the rear of the power supply.
Step 4 Seat the power supply in the SCE 2000 platform by tightening the captive installation screw with
a 1/4-inch flat-blade screwdriver.
Note The power supply is not fully seated until you tighten the installation screw on the faceplate.
This completes the procedures for replacing a power supply in a SCE 2000 platform.
