2.8 Connectors
CAUTION
Only the back panel connectors of the D815EEA2 and D815EPEA2 boards have overcurrent
protection. The D815EEA2 and D815EPEA2 boards’ internal connectors are not overcurrent
protected and should connect only to devices inside the computer’s chassis, such as fans and
internal peripherals. Do not use these connectors to power devices external to the computer’s
chassis. A fault in the load presented by an external device may result in a high output current that
could damage the board, the interconnecting cable, and the external device itself.
