Diagnosing and
Troubleshooting the DL3100
6
The DL3100 performs a self-test upon power-up.
During the self-test, messages will appear in the front-panel display in the
order listed below:
DL3100 SR.XXX.XX (where xxx.xx is the software revision
level)
NODE STATUS OK
EFS 99.9 PERCENT
When the percent of Error Free Seconds (EFS) displays, the DL3100
activates its top level menu loop and the unit is ready for operation.
If an error is detected during the self-test, the unit will momentarily
display an error message, followed by the default display (EFS XX.XX
percent).
Table 6-1 gives a list of possible error messages.
