POWER UP TESTING AND INITIALIZATION
The FXO+ option module executes a partial self test
during the power up sequence, as described in the
TSU 100/120/600
manual. A full self test can be
activated from the Test menu. No initialization input
is required. Any previously configured setting for the
FXO+ is restored automatically upon power up.
Successful Self Test
The green
OK
LED, located with the Module LEDs on
the front panel, turns on when a successful self test is
completed and the configuration is successfully
restored. See the chapter
Operation in the main user
manual .
Failed Self Test
If the FXO+ module fails one or more of the self tests,
a message is displayed in the LCD during power up.
See the
TSU 100/120/600 user manual. Specific
failures of the FXO+ module are identified in the
appendix
FXO+ Failure Messages in this manual.

The red ALARM LED with the Module LEDs on the
front panel turns
on when an alarm condition is
detected.
