POWER-UP AND INITIALIZATION

The Nx56/64 (EIA-530) option module executes a self-test
during the power-up sequence, as described in the TSU
100 User Manual
. No initialization input is required. Upon
power-up, any previously configured setting for the
Nx56/64 (EIA-530) option module is automatically re-
stored.

When the self-test is complete and the configuration is
successfully restored, the LED labeled

OK

in the module

group on the front panel turns ON. For more information,
see Front Panel Operation in Chapter 3, Operation, of the
TSU 100 User Manual. If any alarms are detected during
operation, the red LED labeled

ALARM

in the module

group on the front panel turns ON.
