Installing Stage I/O Cards in Stage 48
After you have removed Stage I/O cards from Mix Rack or SC48,
or if you have purchased new compatible Stage I/O cards, you
can install them in Stage 48.
Stage 48 has three slots that accept Stage I/O cards. Stage I/O
cards are connected to pre-installed 50-pin ribbon cables located
inside Stage 48.
To install Stage I/O cards in Stage 48:
1
Power down Stage 48.
2
Remove power and audio cables from Stage 48.
3
On the front panel of Stage 48, locate the slots where you want
to install the cards. It is recommended that you install cards in
Stage 48 starting with the top slot. If you are installing a com-
bination of input and output cards in one Stage 48, it is recom-
mended that you install input cards above output cards.
4
Remove the card slot covers.
5
Remove the ten back panel mounting screws.
6
Carefully pull the panel partially away from the rack, making
sure not to damage the fan cable attached to the back panel.
7
Disconnect the fan cable before removing the panel entirely.
Set the panel aside.
8
If you are installing output cards in Stage 48, do the following
before proceeding:
• Locate the included extenders.
• For each output card, use two extenders and two of the in-
cluded Phillips head screws to attach the extenders to the
back of the card. Orient the extenders so that the long side
of the extenders lay flat.
9
For each I/O card you are installing, hold the card by its edges
and gently slide the card into the slot.
