Power supply (low voltage)
CAUTION: Do not bend or fold the flat flexible cables (FFCs) during removal or installation. Also, do
not straighten pre-folds in the FFCs. You must make sure that all FFCs are fully seated in their
connectors. Failure to fully seat an FFC into a connector can cause a short circuit in a PCA.
Some parts are sensitive to electrostatic discharge (ESD). Look for the ESD reminder when
removing product parts. Always perform service work at an ESD-protected workstation or mat. If an ESD
workstation or mat is not available, ground yourself by touching the sheet-metal chassis before touching
an ESD-sensitive part.
