2. Addressing and Initial Testing.
a. Set the Address dial on each Model 1172BK and/or 1176BK: set the upper-most Model 1176BKad-
dress to “B”, the next one to “C”, and so on. The AVM-562 Cat 5 output row is permanently ad-
dressed “A”. Follow 1172BK manual for addressing 1172BK. AVX-561 and AVX-661 require a differ-
ent address scheme; refer to the AVX-561 manual.
b. Temporarily plug in the power supplies of all units to a plug strip so that you can turn them all on
at one time. The opening screen on the Model AVX-562 display indicates that the unit is powered
and shows the number of expanders that have been recognized. If this number is different from the
number actually present, look for the bus not being fully plugged into a unit or a unit incorrectly ad-
dressed.
