Appendix A: Card Removal and Replacement 21
9 Locate the raised ridge in the middle of the 50-
pin cable which connects to the 192 Digital I/O
chassis. This ridge is only on one side of the con-
nector, and there is a matching groove on only
one side of the 50-pin connector on the card.
10 Gently push the cable connector into the
card’s connector. The ridge on the cable connec-
tor must be line directly into the groove on the
card connector. Be very careful not to bend any
of the pins.
11 Place the top cover onto the 192 Digital I/O
and replace the screws that you removed with it.
12 Connect the 192 Digital I/O to your HD sys-
tem.
13 Press the Power switch.
14 When you power on the unit, the power LED
should turn orange.
15 Start up the computer.
16 When you boot up the computer, the power
ring should turn from orange to green.
– or –
If it doesn’t, see “Troubleshooting” on page 21.
17 If the ring turns green, and the computer
boots properly, launch Pro Tools.
18 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 cables inside the
192 Digital I/O.
Troubleshooting
If the power ring does not turn from orange to
green when you boot the computer, make sure
you reconnected the DigiLink cable to the Pri-
mary port on the rear of the unit. If the DigiLink
cable is securely fastened and the other end is
plugged into an HD Core or Process card in a
computer that is booted, you may have inad-
vertently disconnected another 50-pin cable
when installing the card.
Hardware Setup Changes
Whenever a card is removed or replaced, the
Hardware Setup I/O routing reverts to original
defaults.
