7.3.10. Status and General Purpose LEDs
After power is applied and the KBox C-101 performs the boot procedure the LEDs show the POST code. In case of a boot
failure within the uEFI the last post code is displayed. When the boot phase is passed without errors, the LEDs change to
their status and general purpose function.
The following table provides information concerning these LEDs (Fig. 10 and Fig. 16).

7.3.11. X205 - Optional FIELDBUS Interface
The optional interface (FIELDBUS) on the front side of the KBox C-101 must
be ordered separately. To add a FIELDBUS interface to the KBox C-101 the
second mPCIe slot, on the bottom of the baseboard, will be used. This
connection can be implemented at factory only.

7.3.12. PCIe Expansion Slots 1 and 2
The KBox C-101 provides two PCIe x4 slots for half-length PCIe add-on cards. The two PCIe x4 expansions utilize a subset
of the connections from the processor chipset PEG port. To access these slots (Fig. 10, PCIe 1 and PCIe 2) in order to
install or remove PCIe x4 expansion cards you have to remove the top side access cover. For better accessibility of the
expansion slots you should to remove the right side access cover (Fig. 24 and Fig. 22, pos 1 and 3) also.
For installation/removing of the mSATA SSD refer to the subsection 10.2.3, “Installing an mSATA SSD”.
