Installing and Removing a Power Supply CAUTION: Never insert or remove a power supply while the power cord is connected. Verify that cord has been disconnected from the power supply before installation or removal. NOTE: Use standard ESD precautions when installing or removing a power supply module. The power supply modules are hot-swappable. Hot swapping allows you to replace a failed power supply without powering down the W-7200 controller during the replacement process. This makes it unnecessary to shut down the W-7200 controller during the replacement procedure. Installing a Power Supply NOTE: If you are adding an additional power supply module, remove the pre-installed power supply module blanking plate and follow the instructions below. If you are replacing a failed power supply, see "Removing a Power Supply" on page 27 before you continue. 1. With a Phillips Head screwdriver, turn the hinged captive screw counter-clockwise until it is loose (they cannot be completely removed). 2. Firmly grasp both of the hinged captive screws and pull the spring loaded hinge down until you are sure the hinges are disengaged. 3. Grasp the power supply blanking plate by the hinged captive screw and slide the plate out. 4. Align the new power supply module with opening in the controller, as shown in Figure 13. 5. Pull down the hinged captive screw on the power supply module and align its tab with the slot on the left side of the opening. 6. Slide the power supply module into the controller. 7. Lift the hinged captive screw and secure the power supply module by tightening the screw with a Phillips Head screwdriver. Take care not to over-tighten the screw.
