Densité 3+ FR1
User Manual
• CPU-ETH2 controller card
• Power cord retaining clips (2)
• A second power supply and AC cord (optional)
• A system card, per order
• Densité-series cards (per order) with associated rear panels
Opening the Front Door
The front door of the Densité 3+ FR1 frame is fastened in place by two captive
thumbscrews, one at each end of the door.
• To open the door, turn both thumbscrews counterclockwise until they release, and pull
the door away from the front of the frame.
• The door is attached to the frame by guides that slide out of the frame as the door is
pulled, and allow the door to be lowered below the frame so that cards and power
supplies can be removed and installed.
• The door can be removed completely by slipping the ends of the guides off the posts
on the door assembly. Note that you must tilt the door on an angle so the guide can
move freely.
There are no electrical connections to the door.
Close the door by sliding it into position against the front of the frame, and turning the
captive thumbscrews clockwise until the door is securely fastened into place
Mounting
The Densité 3+ FR1 housing frame occupies 1RU in a standard 19” rack.
To mount the frame
1 Open the front door to expose the rack mounting flanges at the ends of the chassis.
2 Install the frame in the rack using 4 standard rack-mounting screws (not supplied)
through the four holes in the mounting flanges.
Installing Cards in the Densité 3+ FR1 Frame
All cards can be installed with the frame power on. Each card has a connector which plugs
into the frame’s backplane for distribution of power and connection to the controller card,
and a second connector that plugs into the associated rear panel for inputs and outputs.
IMPORTANT - the rear panel must be installed before the card is inserted into the frame.
If you need to install a Densité 2 series card in this frame, which has Densité 3 slots, please
see
Using Densité 2 cards in the Densité 3+ FR1 Frame , on page 6
To install the rear connector panel
1 If a card is installed in the slot whose rear panel is being changed, remove it as
described below.
2 Remove the existing panel (either blank or belonging to an existing card that is being
changed) by releasing the captive screw(s) on the right-hand side
