NOTE:
Read this Step completely before inserting LIU.
Tables D and E list
alarm indicators that are present after the LIU, for your system
configuration (Feature Package with or without protection), has been
installed. These alarm indicators are listed on the same row as the LIU to
be installed.
NOTE:
After installing
LIU
if the associated
DIGROUP
(s) indicator(s) on
BCU
does not go off, verify that option switch settings on
ADU
and
LIU
are
correct.
Insert
LIU
into appropriate slot in facility shelf (left side for blue bank or right
side for white bank) while observing indicators on
LIU
faceplate. See Table D
or E for alarm indicators that change when the LIU is installed (for your Fea-
ture Package configuration).
Response:
LIU FAIL
indicator lights momentarily then goes off, and the
associated
DIGROUP
(s) indicator(s) on
BCU
goes off.
Comment: If the
LIU FAIL
indicator does not go off, press and hold the
ADU LED TEST
button. If the
LIU FAIL
indicator goes off
while the button is pressed, the circuit pack is not compatible
with the channel bank application. Get the correct code circuit
pack and verify
ADU
option switches are correct. The
AUB27
ADU CMP
indicator will light if the ADU is optioned wrong, an
incompatible LIU was installed, or a wrong LIU option was set.
