Sequence of Events
1. The Local C/CM-10GT media converter module sends the
Remote C/CM-10GT media converter module a signal to go
into test mode.
2. The Remote C/CM-10GT media converter module turns on
test mode.
3. Built In Link Test data is sent from the Local C/CM-10GT
media converter module to the Remote C/CM-10GT media
converter module.
4. The Remote C/CM-10GT media converter module analyses
the received test data and sends its own test data plus a
diagnostic code back to the Local C/CM media converter
module.
5. If the PWR LED on the Local C/CM media converter module
blinks red, this connection may require further testing. The
PWR LED should flash green to indicate that there have been
no errors in the last second.
6. The Built in Link Test continues to run until Switch 1 on the
Local C/CM-10GT media converter module is set to Data
mode.
