FCD-E1 Detecting Errors 6-5
• If the self-test is successfully completed, FCD-E1 starts normal operation, and
its front-panel indicators display the link status, as explained in Chapter 3.
Front-Panel LEDs
The status of FCD-E1 is indicated by the front-panel LEDs. For description of LED
indicators and their functions refer to Chapter 3.
Configuration Error Messages
If FCD-E1 detects a configuration mismatch, it displays an appropriate
configuration error message. These messages appear on either the LCD or the
supervision terminal. Some of the messages are not available on the LCD.
On the control terminal, configuration error messages have the format ERROR,
followed by a two-digit code and a short description of the error message after the
error code. The LCD displays CONFIG ERROR followed by the error two-digit
code, without description. Table 6-2 lists the configuration error messages in order
of their codes and explains each of them. Messages not available on the LCD are
marked with an asterisk (*).
