2.1 Installation of Rear Connector Panels
Grass Valley Densité series cards are each associated with a rear connector panel, which must be installed in the
Densité frame before the card can be inserted.
The MDX-3901 card is designed to fit into Grass Valley
’s Densité-3 or Densité-3+ frame. Four different rear connector
panels are available, the -3+SRP rear panel series fit only in a 3+ frame while the -3DRP rear panel series fit in 3 or 3+
frames:
MDX-3901-7-3+SRP-Q
Single-slot-width panel with 75

MDX-3901-1-3+SRP-Q
Single-slot-width panel with 110

MDX-3901-1-3DP-Q-F

See section
for details of the signal connections available on each of these panel types.
All cards and rear panels can be installed with the frame power on. The card has connectors which plug into a mid-frame
mother board for distribution of power and for connection to the controller card, and a second connector which plugs
directly into the rear connector panel for input and output.
The rear connector panel must be installed with the card out of the frame.
To remove an existing card from the slot, tilt up the swivel handle on the front of the card to lever the connectors
apart, then use the handle to pull the card straight out of the slot.
