Appendix A: Adding or Removing I/O Cards 31
13 Locate the raised ridge in the middle of the
connector on the other end of the 50-pin cable
that connects the I/O card to the HD I/O chassis.
This ridge is only on one side of the connector,
and there is a matching groove on only one side
of the 50-pin connector on the card.
14 Gently push the cable connector into the
card’s connector. The ridge on the cable connec-
tor must line directly into the groove on the
card connector. Be very careful not to bend any
of the pins or to over-stress the card.
15 Replace the top cover on the HD I/O.
16 Replace the original screws.
17 Reconnect the HD I/O to your Pro Tools|HD
system.
18 Power on the HD I/O.
19 When you power on the unit, verify that the
LED ring around the power switch lights orange.
20 Start up the computer.
21 When you start the computer, verify that the
power ring turns from orange to green. (If this
does not occur, see “Troubleshooting” on
page 32.)
22 Launch Pro Tools.
23 Open the Hardware Setup dialog to confirm
that the new card is recognized:
• If you installed a Digital Expansion card,
you should see a new tab called “Digital
9–16.”
• If you installed an AD Expansion card, you
should see a new tab called “Analog In
9–16.”
24 If the new card does not appear in the Hard-
ware Setup dialog, power down, check the seat-
ing of the card, and recheck the cable
connections inside the HD I/O.
Hardware Setup Changes After Adding a
Card
Any additional inputs and outputs provided by
the new card will appear in the Hardware Setup
dialog, with the same controls and parameters
as for the original card of the same type.
For example, if you add an Analog Input card to
the original three cards, a second Analog Input
tab will appear in the Hardware Setup dialog.
You can route these new inputs (which will in
this case be called Analog Inputs 9–16) with the
same controls and parameters as the factory-in-
stalled version of the card.
Pressing the 50-pin cable connector into the card
Whenever a card is added or removed from
a HD I/O, the routing in the Hardware Setup
dialog reverts to the default assignments. If
you have complex routing and or mirroring
in place, note the assignments and reassign
the inputs and outputs after the new card
has been properly identified.
