Hardware overview/installation IVX 128
B.2
Wall-mount transformers
With three or fewer port cards, Base Cabinet I requires a 3-amp transformer (supplied). With four to
seven Port Cards, Base Cabinet I requires a 5-amp transformer and Base Cabinet II a 3-amp transformer.
Base Cabinet I is shipped with and uses a 3-amp wall mount transformer to support up to three
port cards (Base cabinet I and an Expansion Cabinet). However, when Base Cabinet II is added,
Base Cabinet I will require the wall-mount transformer to be swapped with the 5-amp transformer
that is supplied with the Base Cabinet II.
