I have a CS1000E 6.0. I have the TMDI's in slots 0 1 3 and 0 1 4. The card in 0 1 4 will not enable. I tried several times in ld 96 and ld 48 to enl tmdi 0 1 4 fdl. After I hit the enter key after entering enl tmdi 0 1 4 it just sits there. I dont even get a message. Any thoughts. The TMDI in 0 1 3 has the clock controller.
