POWER UP TESTING AND INITIALIZATION
The FXS+ option module executes an abbreviated self-test
during the power-up sequence, as described in the TSU
100/120/600 User Manual. Any previously configured
setting for the FXS+ is restored automatically upon power
up.
Successful Self-Test
The green
OK LED
, located with the module LEDs on the
front panel, illuminates when a successful self-test is com-
pleted and the configuration is successfully restored. See
the Front Panel Operation section in the TSU 100/120/600
User Manual.
Failed Self-Test
If the FXS+ module fails one or more of the self-tests, a
message displays in the LCD during power-up. See the
TSU 100/120/600 User Manual for more information.
Specific failures of the FXS+ module are identified in Ap-
pendix A, FXS+ Failure Messages.
Operation Alarms
The red
ALARM LED
with the module LEDs on the front
panel illuminates when an alarm condition is detected.
