How to Read the 8-Bit POST Code
Due to the fact that only 4 bits are available and 8 bits must be displayed, the POST code output
is multiplexed on the General Purpose LEDs.
The following is an example of the General Purpose LEDs’ operation if the POST configuration
is enabled (see also Table 2-3, “General Purpose LED Function”).
2.11.2
DIP Switch SW1
The CP3003-SA is equipped with one 4-bit DIP switch, SW1, used for board configuration.
2.11.3
USB Interfaces
The CP3003-SA supports four USB 2.0 ports, two on front I/O and two on the rear I/O
CompactPCI connector J2, as well as one USB 3.0 port on the high-speed I/O extension
connector J14. The four USB 2.0 ports are high-speed, full-speed, and low-speed capable. The
two USB 3.0 port is super-speed capable.
One USB peripheral may be connected to each port. For connecting more USB devices to the
CP3003-SA than there are available ports, an external USB hub is required.

Note ...
Under normal operating conditions, the General Purpose LEDs should not re-
main lit during boot-up. They are intended to be used only for debugging purpos-
es. In the event that a General Purpose LED lights up during boot-up and the
CP3003-SA does not boot, please contact Kontron for further assistance.
