Chapter 3: Installing HDX Cards 21
Connecting Multiple HDX
PCIe Cards Using HDX TDM
Cables
In systems that have more than one card, you
must connect all the HDX PCIe cards to each
other with HDX TDM cables (custom SATA
cables). Each HDX card has two ports along the
top of the card, labeled
IN and OUT. Data com-
munication across multiple cards is achieved by
connecting the OUT port of the first card to the
IN port of the next card with an HDX TDM
cable.
To connect HDX PCIe cards with an HDX TDM
cable:
1 Connect the end of the HDX TDM cable
labeled OUT to the OUT port of the first HDX
card.
2 Connect the other end of the HDX TDM cable,
labeled IN, to the IN port of the second HDX
card.
3 For systems with more than two cards, connect
each additional card to its preceding card. Use
additional HDX TDM cables to connect card
pairs together, as described above, until all cards
are connected. (Each HDX card is packaged with
an HDX TDM cable.)
