Cyclades-PR4000

What to Do if the Router Does Not Work or Stops Working.

1 Check that the cables are connected correctly and firmly.

2 Confirm that the Link LED is lit for the (Fast) Ethernet Port being used, indicating proper Ethernet cable termination. If it is not lit, check both ends of the (Fast) Ethernet cable and the hub connection. If it is lit, test the interface as described in the next section.

3 If port 2 is not being used, the port 2 LED doubles as a CPU status LED. If port 2 is being used, disconnect the cable temporarily to see the CPU status. The Port 2 LED should blink consistently one second on, one second off. If this is not the case, see figure A.2 for an interpretation of the blink pattern.

FIGURE A.2 PORT 2 (CPU) LED CODE INTERPRETATION

Note: The Ethernet error mentioned in Figure A.2 will occur automatically if the Fast Ethernet link is not connected to an external hub during boot. If the Fast Ethernet is not being used or is connected later, this error can be ignored.
