Check the board IDs of the installed cards. To this, you must
get inside the platform.
Analog-line interface cards are placed in the slots numbered
PCI 5 through PCI 3, from bottom to top. Board IDs assignment
are as follows: the card in PCI slot 5 is assigned ID 0;
the card in PCI slot 4 is assigned ID 1; and the card in PCI
slot 3 is assigned ID 2.
If necessary, change the board IDs of the incorrect cards and
then replace the PC cover and restore
power.
