Power supplies, which exist in pairs, provide DC to all of the Pilot components. If one power supply fails, the other supply carries the full load. This situation creates a risk of Pilot failure should the other power supply also fail.
Before handling a component, touch a grounded surface to discharge any static electricity.
Attach an electrostatic discharge (ESD) wrist strap to your wrist, and stand on an ESD mat while replacing components.
Ensure that you have a similar replacement power supply available before you start the replacement procedure.
Initiate Guided Maintenance only when you are able to replace the power supplies immediately.
