Verifying Module
Operation
The GEN Interface Modules each have one Module Status LED and two

proper module operation. During the power-on diagnostic test, both
the Module Status and Port Status LEDs flash for approximately 1
second, and then reflect the active status of the module as described in
Table 3.
