Card Removal and Replacement
Removing an I/O Card
In the event of a problem with either of the dig-
ital I/O cards in your 192 Digital I/O, you can re-
move the card and send it to Digidesign for re-
pair. The modular nature of the Pro Tools|HD
system allows you to simply return the specific
card, instead of the entire 192 Digital I/O.
Pro Tools|HD will continue to function while
missing a single card. It will not function if more
than one of the factory-installed cards is re-
moved.
To remove an I/O card from the 192 Digital I/O:
1 Power off and disconnect the 192 Digital I/O
from your Pro Tools|HD system.
2 Make sure that the equipment is properly
grounded.
3 Remove the top cover of the 192 Digital I/O
by extracting the 16 small Phillips-head screws
around the edges of the top cover, and lift it off.
Put the screws in a safe place.
4 Remove the five screws on the front plate of
the card to be removed.
5 Gently pull the 50-pin connector off of the
edge of the card.
6 Pull the card out by gripping the edges be-
tween your thumb and forefinger on each side.
Pull straight back, lifting very slightly to avoid
contact between components on the underside
of the card and the 192 Digital I/O back panel
faceplate.
7 Place the card immediately in an anti-static
bag and send it to Digidesign according to in-
structions from the Customer Support dept.
Before handling any of the cards or internal
components of 192 Digital I/O, discharge
any static electricity by touching the outer
casing of the power supply.
When you pull a card out, pay particular at-
tention to keeping components on the sur-
faces of the card from bumping into any of
the internal components or the back panel
faceplate on the 192 Digital I/O.
