Removing Cards from IOx-Equipped Mix
Racks
This section describes how to remove cards from an
IOx-equipped Mix Rack. IOx is installed in slot A of Mix Rack,
AI16 Input cards are installed in slots B–D, and an output card is
installed in slot E.
To remove cards from an IOx-equipped Mix Rack:
1
Inside the Mix Rack, locate the AI16 card in slot B.
2
Disconnect the ribbon cable attached to the card by pushing
the tabs on the card’s port outwards to release the cable. The
ribbon cables attached to the Stage I/O cards will be connected
to the Ethernet Snake card when it is installed in the rack.
3
Mark this cable end “A” to help identify the cable when con-
necting it to the Ethernet Snake card.
4
Loosen the two captive thumbscrews that secure the card to the
chassis of Mix Rack.
5
Repeat the procedure to remove the card from slot C of Mix
Rack. Mark the cable end “B.”

If you want to relocate the AI16 card in slot D to Stage 48, re-
move the card and mark the cable end “C.”

If you want to relocate the output card in slot E to Stage 48, re-
move the card and mark the cable end “D.”
Moving an AI16 Input Card to Slot D
To move an AI16 card to slot D of Mix Rack, you must first move
two internal I/O card brackets in slot D to secure the back of the
AI16 card to the chassis of the rack.
To move an AI16 Card to slot D:
1
Inside the open front panel of Mix Rack, locate the two interior
IO card brackets attached to the left and right sides of Mix
Rack in slot D.
2
Use a #1 Phillips screwdriver to remove the brackets. The
screws are accessed on the outside of the rack.
3
Align the brackets with the bracket holes just behind the orig-
inal bracket holes, and attach using the original screws.
4
Hold the card by its edges and gently slide the card into slot D.
5
Secure the card to the chassis of Mix Rack by tightening the
captive thumbscrews.

Connect the ribbon cable marked “C” to the connector on the
card.
