Power Up
The various front LED indicators and configuration switches are illustrated
in Figure 10. Upon power-up, all LEDs should light for the duration of the
initialization process. After initialization the Power LED will be on and the
red Network Module LED (labeled NM) should go off. All other LEDs
report detected conditions within the frame and the installed modules. If
the NM LED does not go off, the board needs servicing.

Table 1 on page 17 describes all the module’s LEDs and the conditions indi-
cated.
