Table 9. Error codes signaled via service LEDs
"Slow" means blinking with a frequency of 1 Hz, "fast" means blinking with a
frequency of 10 Hz.
2.4.3 Ethernet Port Status LEDs
Each Ethernet user port (1 to 8) provides two LEDs to display its status (LNK x and
ACT x). The display LEDs act as described in the following table.
Table 10. Ethernet port status LEDs
An alternative LED configuration with one LED indicating link status and receive
activity and the other indicating transmit activity can be realized on demand.
2.5 CompactPCI Interface
The F302 supports a 32-bit 33-MHz CompactPCI interface fully compatible with
CompactPCI specification PICMG 2.0 Rev. 3.0. The board works with 3.3V for
V(I/O) only. For full CompactPCI functionality only the J1 connector is needed,
therefore the board only has a J1 connector to the bus.
Connector type of J1:
• 110-pin shielded, 2mm-pitch, 5-row receptacle according to IEC 917 and IEC
1076-4-101
The pin assignment of connector J1 as defined in the CompactPCI specification will
not be repeated here.
