Faults

Previous Hardware

In 2010, the CPU socket was damaged during removal of the socket cover. A pin for the second memory channel was severely damaged. The channel's operation was restored, however the CPU is no longer removable as doing so would render it nonoperational.

In 2012, the NEC onboard USB3.0 controller was destroyed by an external power surge from a connected device. USB2.0 remains functional.

In 2013, both Marvell onboard gigabit Ethernet controllers burned out from excessive network traffic. They were supplemented by an HP NC360T.

In 2014, the Marvell onboard SATA3 controller failed for an unknown reason. SATA2 remains functional.
