Hi,

I'm not entirely sure if I'm posting in the right place (just registered).

I'm having problems with one of the cards used in Alcatel's 1540 telephone system.
The card is synth-1 (also called compact adm-1).

The card fails to initialize properly up on power up.
On power up, the bottom two LEDs light up (red and green) and then both LEDs go off indicating failure in bootup of the board.
One of the supply rails drops from 2.8v to 1.6v which indicates to me that the board isn't powering up properly.

I would appreciate some insight into what could be causing the board failure and possible solutions.

Thanks!
