ply. Do not forget to tighten the screws of the board with a screwdriver.
Note: Each time you insert or replace any board in the DBS, you must download again the same
software (click on "download" button without activing nor referencing it) This will occur the newly
inserted or replaced boards of the BS to be updated.

I Extraction of the
board manifesting
a fault
For the AMD,TNT, IBS and CPL boards, the color
of their graphic representation in the BS
supervision screen changes from white to grayed-
out.
However, in the case of a module or ventilation
block, the color of the graphic representation
remains unchanged.
In the alarms list, the extracted board appears with
"Board_missing" alarm (for the AMD, TNT, IBS
and CPL boards), or "Comm_loss" alarm.
In the specific case of the AMD board, the IBS and
X-Pol RBS boards associated with it give rise to a
"Comm_loss" alarm.

II Insertion of the new
board
The red "F" LED on the front edge of the board
remains lit throughout the initialization and self-
configuration phase of the board, then is
extinguished.
The alarms then disappear from the alarms table.
In the specific case of the AMD board, not only do
the alarms relating to it disappear, but those of its
associated IBS and X-Pol RBS boards can also
appear.
In addition, the NTs attached to it are automatically
(re)integrated in the network and the E1 or IP
services become automatically accessible.

cing nor activation (see § 7.3.12 –).
