Card Placement Rules
Systems are pre-assembled at the factory, but for eld
updates, observe the following rules. Slide each card into
the HLX card cage and secure using the provided screws.
1. The rst card slot must have a source card installed.
2. Slot 2 may have a source card installed or may be left
empty. Do not install a zone card in slot 2.
3. Slot 3 accepts either a source or zone card.
5. Slots 4, 5, and 6 accept zone cards only*.
6. Sources and zones are numbered sequentially, left to
right, starting with the top card in the card cage.
7. Adding cards to an existing system requires inserting the
card at the bottom of the respective stack; a source card
should be added after the last source card in the system,
shifting zone cards down if necessary. Zone cards should
be added in the next available slot, below the existing
zone cards.

be numbered in order, based on the card location in the
