== FITLET2ERR005: Built in Ethernet port is disappearing on start-up ==
* '''Date''': 28-Apr-2019
* '''Symptom''': One of the built in Ethernet ports is disappearing on start-up.
* '''Applies to''': fitlet2 configured with either - FC-PCI Rev1.0-1.1, FC-CEM Rev1.0, FC-POED Rev1.0.
* '''Cause''': In FC-PCI Rev1.0-1.1, FC-CEM Rev1.0 and FC-POED Rev1.0 rails 3.3V_A and 3.3V_S are connected in way which affects power sequencing. As a result, in rare cases on-board Ethernet controller's reset is released before PCI bus initialization is complete which results in Ethernet controller being unrecognized.
* '''Workaround''': Covered under warranty. Compulab will replace FC-PCI FACET Cards exhibiting errors
* '''Fix''': Fix applied to FC-PCI Rev1.2, FC-CEM Rev1.1, FC-POED Rev1.1.
== FITLET2ERR006: RS-485 half duplex not working on fitlet2 configured with FC-SCG==
* '''Date''': 28-Apr-2019
* '''Symptom''': RS-485 half duplex is not working on fitlet2 configured with FC-SCG.
* '''Applies to''':fitlet2 configured with FC-SCG Rev1.0
* '''Cause''': In FC-SCG Rev1.0 a signal that controls RX/TX direction is disconnected. As a result RS485 half-duplex does not function.
* '''Workaround''': Full duplex should work well. Covered under warranty, Compualb will replace FC-SCG FACET.
* '''Fix''': Fix applied to FC-SCG Rev1.1
