Line Card Installation

When all common equipment has been installed, and is operating normally, install line cards according to
the appropriate individual line card user manuals.

System Power-Up and Initialization

After installing all common equipment and line cards as directed in this user's manual, and in applicable
line card user manuals, apply power to the D/I Mux III shelf. Feature Group 8.4/9.4/1.4 includes a
power-up cycle that features a 25-second self-test, and a 20-second initialization routine (including
warm-up). During the self-test, the CCU/AMCU/MCU ACO LED flickers, and the BYP LED remains lit.
Upon completion of self-test, the initialization routine begins, during which the LIU LEDs cycle on
and off.
Note: Depressing the BYP button during power-up causes the CCU/MCU to "bypass" the checksum test.
