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.
Note: 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 7
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
3 Position the new panel and secure it in place with the captive screw(s) on the right-hand
side.
Card Installation and removal:
1 Open the front door of the frame
2 To install a card into an empty slot, slide the card into the slot with the swivel handle to the
right, and push gently on the handle to seat the connectors. If the card requires a double-
width rear panel to accommodate a large number of connectors, it should be inserted into
the lower slot. Inserting the card into the wrong slot will not damage the card, and will be
flagged by the on-card status LED flashing red to indicate that there is no connection to the
rear panel.
N.B. the rear panel must be installed before the card.

Using Densité 2 cards in the Densité 3+ FR1 Frame
The Densité 3+ FR1 frame supports Miranda Densité 2 series cards. Should you need to install a
Densité 2 card in your Densité 3+ FR1 frame, you will need two adapters – one for the card, and
one for the rear panel. These adapters extend the height of the Densité 2 devices so that they
will fit into the slots of the Densité 3+ FR1 frame.
Card adapters:
There are 3 different types of adapters that
can be used, depending on the Densité 2
card geometry:
o DENSITE 3-EXT-A
o DENSITE 3-EXT-B
o DENSITE 3-EXT-C
Install these on the Densité 2 card as
follows:
1 Fit the top edge of the card into the
holding slot along the bottom edge of
the adapter.
2 Align the holes in the top of the card with the holes on the adapter, and secure them
together with the two provided screws and lock washers, as shown in the figure.
Rear Adapters
3-RU rear panel adapters are available for Single and Double Densité 2 rear panels:
•DENSITE SRP-3RU for single slot-width rear panels
•DENSITE DRP-3RU for double slot-width rear panels
Install the adapter and the rear panel as follows:
1 Position the adapter at the left of the empty slot(s) on the rear of the frame.
2 Use the captive screw in the adapter to fasten it securely in position.

of holes in the plate Several pairs of holes are provided to
accommodate different sizes of plugs. Use the holes that
position the clip closest to the body of the plug.
Position the clip vertically and insert the plug into the
socket. Then, rotate the clip down and press the cord into
the gripping loop of the clip.
Ventilation
Ventilation for the frame is provided by two fans, one located at each end of the rear panel. The
fans draw air through the frame from the front and exhaust it to the rear. Ventilation slots are
provided in the front door of the frame to allow air to flow into the frame.
An air filter is installed in the front door behind the slots.
•Ensure that the front door ventilation slots are not obstructed.
•Check the air filter regularly to ensure that it is not plugged up with debris.

The filter may be cleaned by rinsing in warm water. Dry thoroughly before replacing it in the
frame.
In addition to the main frame cooling fans, each installed power supply has its own fan that pulls
air into the front of the supply. This fan only operates when the frame temperature is high.
Fan Speed Control
A slider switch beside the controller-side fan on the rear panel allows the speed of the two rear-
panel fans to be specified by the user. Two settings are provided:
•FULL - the fans operate at top speed at all times.
•VAR - the fan speed is managed by the controller card, which is monitoring the temperature
inside the frame.
Use a small tool (e.g. a pen tip or a small screwdriver) to change the switch setting.
GPI
Alarms generated on the controller card may be reported on the GPI connector on the rear
panel.
Users who wish to utilize this alarm reporting mech-
anism should be aware of the circuit driving the GPI
connector, in order to correctly interpret its
signalling.
Field-Serviceable Items
Field-serviceable items on the Densité 3+ FR1 frame itself include the power supplies, the
controller card, and the ventilation fans.
The power supplies and controller card are located behind the door on the front panel.

Changing the Power Supply
The Densité 3+ FR1 frame supports dual redundant hot-swappable power supplies. The basic
configuration includes a single supply, plus an empty slot for the optional redundant power
supply. Installing a second power supply module and applying power to it automatically
engages the redundant supply mode. Each power supply has its own power socket on the rear
panel, and should be connected to the AC supply using the supplied power cord or other
approved cord.
•A single power supply can be installed in either of the two slots, but it makes sense to install
it in the right hand slot so that it is not necessary to remove the controller card if you need to
remove the power supply.
•Power integrity is enhanced if the two supplies are plugged into different circuits
To install or change a power supply module:
1 Open the front door of the frame
2 If you are removing the left-side power supply, you must first remove the controller card.
See the following section.
3 Remove the power supply module by pulling on the handle on its front panel and sliding it
out of the frame
4 Slide the new power supply module into the slot, and push it gently into position to seat
the connectors. There is no guiding slot - the supply base sits on the floor of the frame.
5 If you removed the controller card in step 2, reinstall it according to the instructions in the
next section.
6 Close the front door of the frame. The door secures the power supplies in place.
Replacing the Controller Card
The Controller card is located on the upper left-hand side of the frame, above the power supply.
To replace the card, proceed as follows:
1 Open the front door of the frame.
2 Grasp the metal handle on the upper left-hand side of the card; it will slide out so that it can
be gripped properly.
3 Pull gently on the handle until the card is released from the rear connector, and then slide
the card out of the frame.
4 Slide the new card into the controller slot, and push gently on the card edge to engage the
rear connectors.
5 Be sure to close the front door before operating the Densité 3+ FR1 frame, to ensure proper
ventilation.

Replacing the Frame Ventilation Fans
In case of failure of one of the two cooling fans on the rear of the frame, replace it according to
the following steps.
1 Procure a replacement fan assembly.
It is comprised of a fan and an
attached circuit board. It is available
from Miranda as part #0969-0400
2 Remove the defective fan from the frame:
•Remove the two screws that secure the fan assembly to the frame and pull the fan
assembly straight out of the frame.
•Retain the screws, as they will be used to install the replacement fan assembly.
3 Install the replacement fan:
•Slide the new fan assembly into the opening on the rear panel, pushing it straight in and
ensuring that the connector on the assembly mates with the socket in the frame.

NOTE: the two ventilator fans are mounted at different
angles, as shown in the above figure. Align the circuit
board on the fan assembly with the notches in the
edge of the rear-panel opening (see arrows in figure at
right) to ensure the correct alignment.
The socket into which the circuit board connects is
hidden from view by the fan assembly during installa-
tion and there is no guide to ensure that they are
aligned. The easiest way to make sure that the con-
nector and socket have mated properly is to install the
fan with the frame power turned on. You will hear the
fan start up when the connection is made.
•Use the two screws that were retained when the old fan assembly was removed to
secure the new fan assembly to the rear panel.
