Chapter 2: Installing a Mix Engine Card 5
Mix Rack Mix Engine Card Installation
Installing an additional Mix Engine card in Mix Rack consists of
the following steps:
• Preparing for installation by opening Mix Rack and discon-
necting existing ribbon cables
• Installing the new Mix Engine card
• Connecting the included TDM FlexCable, and reconnect-
ing existing ribbon cables
• Completing and confirming installation
Preparing the Mix Rack
To prepare a Mix Rack for Mix Engine card installation:
1
Shut down the system.
2
Disconnect all audio cables attached to the Mix Rack.
3
Remove the Mix Rack front panel faceplate by unscrewing its
mounting screws (#1 Phillips).
4
Via the open front panel, carefully disconnect the 50-pin rib-
bon cables from each Stage I/O card (AI16, AO16, XO16,
and/or AT16 cards) or the Ethernet Snake card. Release the
ribbon cable connectors from the ports on the cards by pushing
the two plastic latches securing each connector outwards.
5
Locate the two Mix Engine cards and the Hub 48 card cur-
rently installed in Mix Rack. Depending on your version of
Mix Rack, Mix Engine cards may be installed adjacent to the
Hub 48 card, or there may be one or more empty slots between
the second Mix Engine card and the Hub 48 card.
Before handling any card, discharge static electricity from
your clothes or body by touching a grounded metal surface,
such as the Mix Rack’s rack rails.

Figure 9. Removing the Input and Output Card ribbon cable

Disconnect the ribbon cables from the Stage I/O cards or the
Ethernet Snake card only. Do not disconnect the black I/O
card ribbon cable connectors from the Hub 48 card. Doing so
could damage the Hub 48 card.
