3.2.5.5 Power supply mode LED (SYS)
The SYS LED on the front panel of the CPC505 (see Figure 2-2) is blue in color and is used to
indicate the module's power supply mode. It is used to indicate that the shutdown process is
complete and the board is ready to be removed from the slot, see Table 3-9 - SYS LED Status.
3.2.6 CompactPCI connectors
A complete set of CompactPCI connectors consists of five connectors from
J1 to J5. They are assigned as follows:
● J1 and J2 - the 64-bit CompactPCI interface, including PCI bus signals,
bus access organization, timing, and power.
● J3 ensures Rear I/O and PICMG 2.16 interface functions.
● J4 and J5 ensure additional Rear I/O interface functions.
The CPC505 module is designed in accordance with the CompactPCI bus
architecture. The CompactPCI standard is electrically identical to the local
PCI bus, however improvements have been made to such systems to allow
them to be used in harsh industrial environments with an increased number
of expansion slots.
