How to interpret the LEDs on the EtherLite

Solution:

The "Link" LED simply indicates that the Ethernet chip believes it has a decent carrier on the line.  This does not necessarily guarantee that TCP/IP communications will be successful.

The "ON" LED flashes rapidly when the unit is ready and waiting to be assigned an IP address by the bootp/DHCP server.

There is one code that is useful to know, however.  It is 67.  This will be where the ON LED flashes 6 times, short pause, then 7 times, then a long pause.  In other words, it might look like:

The pattern repeats until the unit is powered off and back on again.  It means that the bootp or DHCP server has tried to assign us an IP address that appears to already be in use on the network. Most times, it's an "illegal" laptop on the net or a temporary test machine using an unassigned IP address.  Regardless, the solution is to either pick another IP address (by reconfiguring bootp or DHCP), or by eliminating the conflicting host, and then power cycling our unit so it can get an IP address it can use.

NOTE: There are other codes that may show up on this same LED, but if it's anything other than the 67 mentioned above, and power cycling the unit doesn't fix it, the only solution is to send it in for repair. The hardware is simply failing self test and will not function until it is repaired.
