POST Test Error Code Sample

NOTE: This example applies to 8, 16, 32, and 48 port LX units. The 16, 32, and 48 port LX units use only the first eight LEDs when generating error codes.

The following sample illustrates the Port Status LED sequence for Error 2030 (Reading Invalid Value from PLD System Fail Status Register) on the LX-4008. In this example:

1.A POST test failure occurs on an 8-port unit. All LEDs flash eight times, very quickly, then the error code is displayed.

2.You record that LED 3 turns on. Again, all LEDs flash eight times very quickly, then the rest of the error code is displayed.

3.You record that LEDs 3 and 4 turn on. Figure 22 explains how to interpret the sample error code. NOTE: In hexadecimal, 0 indicates the LED is OFF. 1 indicates the LED is ON.

Each group of four LEDs is converted to a hexadecimal value as follows:

•0 = 0000

•1 = 0001

•2 = 0010

•3 = 0011

•4 = 0100

•5 = 0101

•6 = 0110

•7 = 0111

•8 = 1000

•9 = 1001
