2 Installation

2.1 Installation of Rear Connector Panels

Miranda 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 HDA-1851 card is sized to fit into Miranda’s Densité-2 frame. Two different rear connector panels are available to
fit the Densité 2 frame:

• HDA-185N/186N-SRP – 1 input and 4 outputs

• HDA-185N/186N-DRP – 1 input and 9 outputs

With the use of an available adapter, the HDA-1851 can also be installed in a Densité-3 frame (see section 2.3
below). A rear connector panel for this frame is available for the HDA-1851:

• HDA-185N/186N-3SRP – 1 input and 7 outputs

The two Densité-2 rear panels can also be used in a Densité-3 frame, with the addition of available adapters:

• HDA-185N/186N-SRP + DENSITE SRP-3RU – 1 input and 4 outputs

• HDA-185N/186N-DRP + DENSITE DRP-3RU – 1 input and 9 outputs

All cards and rear panels can be installed with the frame power on. The card has connectors which plug into a mid­frame 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.

Densité-2 frame – rear panel installation Densité-3 frame – rear panel installation

To install the connector panel:

(NOTE - if you are installing a Densité-2 rear panel plus adapter in a Densité-3 frame, please go to section 2.3)

1. If a card is installed in the slot whose rear panel is being changed, remove it as described above.

HDA-1851 | 7

GUIDE TO INSTALLATION AND OPERATION

2. Remove the existing panel (either blank or belonging to an existing card that is being changed) by releasing the
captive screw(s) at the bottom.

3. Position the new panel and secure it in place with the captive screw(s) at the bottom.

2.2 Card Installation

Once a matching rear connector panel has been installed, install the HDA-1851 card as follows:

1. Open the front panel of the frame.

2. Slide the HDA-1851 card into the slot and push gently on the handle to seat the connectors.
If the card is used with the HDA-185N/186N-DRP double-width rear panel, it should be inserted into the right-

hand 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.

3. Close the front panel of the frame.

2.3 Installing Densité-2 Cards and Rear Modules in a Densité-3 Frame

The Densité-3 frame supports many Miranda Densité-2 series cards, including the HDA-1851. Should you wish to
install the HDA-1851 card in your Densité-3 frame, you will need an adapter for the card. You may use the 3 RU rear
panel that is available for the HDA-1851 (HDA-185N/186N-3SRP), or you may use one of the two 2 RU rear panels.
In the latter case, an adapter will also be required for the rear panel, as described above. These adapters ex tend the
height of the Densité-2 devices so that they will fit into the slots of the 3 RU Densité-3 frame.

Card adapters:

There are 3 different types of adapters available,
depending on the Densité 2 card geometry, so be
sure to order the adapter designed to fit the HDA­1851 card:

Densité 3 – EXT A
Install the adapter on the HDA-1851 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.

GUIDE TO INSTALLATION AND OPERATION

Rear adapters:

3-RU rear module adapters are available for Single and Double Densité-2

o DENSITE DRP-3RU
o DENSITE SRP-3RU

Install these as follows:

1. Position the adapter at the top 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.

3. Slip the top of the 2RU rear panel into the slot

at the bottom of the adapter, and secure it to
the frame using the captive screw at the
bottom of the panel.

3 Operation

3.1 Card-Edge Status LED

The status monitor LED is located on the front card-edge of the HDA-1851, and is visible through the fro nt access door
of the DENSITÉ frame. This multi-color LED indicates the status of the HDA-1851 by color, and by flashing/steady
illumination.

The chart shows how the various error conditions that can be flag ged on the HDA-1851 affect the LED status.

• If a cell is gray, the error condition cannot cause the LED to assume that status

• If more than one LED status is possible for a particular error condition, the status is configurable.

See Section 3.2.2 on page 12 for details.

• The factory default status is shown by a 

The LED will always show the most severe detected error status that it is configured to display, and in the chart error
severity increases from left to right, with green representing no error/disabled, and flashing red the most severe error.

3.2.1 Overview

Push the SELECT button on the HDA-1851 card edge (see Section 1.4) to assign the local control panel to operate
the HDA-1851. Use the control panel buttons to navigate through the menu, as described bel ow.

All of the cards installed in a Densité frame are connected to the frame’s controller card, which handles all interaction
between the cards and the outside world. There are no operating controls located on the cards themselves. The
controller supports remote operation via its Ethernet ports, and local operation using its integrated control panel.

The local control panel is fastened to the controller card by a hinged
connector, and when installed is located in the front center of the
frame, positioned in front of the power supplies. The panel consists
of a display unit capable of displaying two lines of text, each 16
characters in length, and five pushbuttons.

The panel is assigned to operate any card in the frame by pushing
the SELECT button on the front edge of that card.

• Pushing the CONTROLLER button on the control panel
selects the Controller card itself.

• The STATUS LED on the selected card flashes yellow.

HDA-1851 | 11

GUIDE TO INSTALLATION AND OPERATION

The local control panel displays a menu that can be navigated using the four pushbuttons located beneath the display.
The functionality of the pushbuttons is as follows:

[+] [–] Used for menu navigation and value modification
[SELECT] Gives access to the next menu level. When a parameter value is shown, pushing this button once

enables modification of the value using the [+] and [–] buttons; a second push confirms the new value

[ESC] Cancels the effect of parameter value changes that have not been confirmed; pushing [ESC] causes the

parameter to revert to its former value.

Pushing [ESC] moves the user back up to the previous menu level. At the main menu, [ESC] does not

exit the menu system. To exit, re-push the [SELECT] button for the card being controlled.

If no controls are operated for 30 seconds, the controller reverts to it s normal standby status, and the selected card’s
STATUS LED reverts to its normal operating mode. If a parameter was changed on the card but not submitt ed
(SELECT was not pressed) and the 30 second timeout occurs, the parameters will be confirmed as if the SELECT key
had been pressed.

3.2.2 Menu for local control

The HDA-1851 has operating parameters which may be adjusted locally at the controller card interface.

• Press the SELECT button on the HDA-1851 front card edge to assign the Densité frame’s local control panel
to the HDA-1851

• Use the keys on the local control panel to step through the displayed menu to configure and adjust the HDA-
1851

• Note that card status messages and error reports are the first items that appear when the select button is
pushed.
