Online LED
The front panel of the Passport 8672ATME Module has an Online LED that
indicates whether or not the module has power applied and is initialized correctly.
When the Passport 8672ATME Module is first inserted into the chassis, the Online
LED turns amber until the board is recognized by the system and passes a
power-on self-test. If the module fails the self-test, the light is off. When the board
passes the self-test and goes online, the LED illuminates a solid green.
Note: You cannot configure the Passport 8672ATME Module until the
online LED on the module is steadily lit green and you have inserted at
least one MDA.
