GUIDE TO INSTALLATION AND OPERATION

2 Installation

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 ADX-1901 card is designed to fit into Grass Valley’s Densité-2 frame. Two different rear connector panels are
available for this configuration. Due to connector space requirements, a double-slot-width rear panel is necessary:

• ADX-1901-DRP Double-slot-width panel for Densité-2

• ADX-1901-DRP-F Double-slot-width panel for Densité-2 with fiber I/O

With a factory-installed adapter mounted on the ADX-1901 card, it can be installed in a Densité-3 frame. In this case,
only a single-slot-width panel is required. Two rear panels are av ai lab le:

• ADX-1901-3SRP Single-slot-width panel for Densité-3

• ADX-1901-3SRP-F Single-slot-width panel for Densité-3 with fiber I/O

See section 2.4
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.

ADX-1901 | 3

GUIDE TO INSTALLATION AND OPERATION

To install the connector panel:

Note – the procedure is the same for both Densité-2 and Densité-3 frames.

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

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 ADX-1901 Card Installation

Note – The card itself (ADX-1901) is designed to fit the D ensi t é-2 frame. If it was ordered for the Densité-3 frame

(ADX-1901-3RU), it will be delivered with an installed adapter that allows it to fit into the taller frame. The
adapter can be ordered separately and user-installed if required.

Once a matching rear connector panel is in place, install the ADX-1901 card as follows:

1. Open the front panel of the frame.

2. Slide the ADX-1901 card into the slot and push gently on the handle to seat the connectors.
When using the double-slot-width rear panel in a Densité-2 frame, the card should be inserted into the right-

most of the two slots. 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.

4 Local control using the Densité fra me c ont rol panel

4.1 Overview

Push the SELECT button on the ADX-1901 card edge
(see section 1.4) to assign the local control panel to
operate the ADX-1901. Use the control panel buttons
to navigate through the menu, as described below.

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 wor ld .
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 front of the
CPU-ETH2 controller card, 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.

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

5.13 Alarm Config panel

This panel allows the alarm reporting of the ADX-1901 to be
configured. The panel opens in a new window when th e button is
clicked, and can be resized if needed.

The panel is organized in columns.

Status/Name

This contains an expandable tree listing all the alarms reported by
this ADX-1901 card.

• Each alarm name includes an icon that shows its current

status

• Some alarms may be text-only and the alarm status is shown

in the name and not by a status icon

• The figure shows the entire tree, but some repetitive alarms

were removed to reduce the size of the image.

The Card LED and Overall alarm columns contain pulldown lists
that allow the level of contribution of each individual alarm to the
alarm named in the column heading to be set.

• If there is no arrowhead in the box, there is no pulldown and

the alarm is not user-configurable

Card LED

This column allows configuration of the contribution of selected
individual alarms to the status LED located on the front card edge.

Overall Alarm

This column allows configuration of the contribution of each individual alarm to the Overall Alarm associated with this
card. The Overall Alarm is shown in the upper left corner of the iControl panel, and also appears at the bottom of the
Status/Name column.

GSM Contribution

This column allows configuration of the contribution of each individual alarm to the GSM Alarm Status associated with
this card. GSM is a dynamic register of all iControl system alarms, and is also an alarm provider for external
applications. The possible values for this contribution are related to the Overall alarm contribution:

• If the Overall alarm contribution is selected as Disabled, the GSM alarm contribution can be set to any available
value

• If the Overall alarm contribution is selected as any level other than disabled, the GSM contribution is forced to
follow the Overall Alarm.

Log Events

iControl maintains a log of alarm events associated with the card. The log is useful for troubleshooting and identifying
event sequences. Click in the checkbox to enable logging of alarm events for each individual alarm.

Levels associated with these alarms:

The pulldown lists may contain some or all of the following options:

The alarm makes no contribution (black icon)
The alarm is of minor importance (yellow icon)
The alarm is of major importance (orange icon)
The alarm is of critical importance (red icon)
The alarm exists but has no effect (used for text and composite alarms)

Shortcut: if you click in one of the Set All boxes beside a section heading, you will open a pulldown that lets you
assign a level to all alarms in that section of the column simultaneously.

Once the alarms are configured, you may accept the changes or discard them:

Overall alarm and GSM contribution follow card LED

Click in the checkbox to force the Overall alarm and GSM
contribution to be identical to the Card LED status

• All Overall alarms and GSM contributions for which
there is a Card LED alarm will be forced to match the
Card LED alarm

• All Overall Alarms and GSM contributions for which
there is no Card LED alarm will be forced to Disabled

A warning box will open allowing you to confirm the action,
since it will result in changes to the configuration and there
is no undo function.

GUIDE TO INSTALLATION AND OPERATION

ANNEX 2 – Installing the Optical Interfa c e

Installing and removing the Fiber I/O interface cartridge requires special care. This annex describes the process.

Some rear panels used with the ADX-1901 incorporate a fiber optic interface. The interface consists of two parts:

• A socket on the rear panel into which an SFP interface module is plugged

• An SFP (Small Form-factor Pluggable) m odule into whi ch the opt ical fibers are plugged, and which incorporates

the optical/electrical interface

Cautions and Warnings

SFP Transmitter modules contain a class 1 laser, which emits invisible radiation whenever the module is
powered up. Because the SFP is hot-swappable, the module may be powered up as soon as it is installed.

DO NOT LOOK INTO AN OPERATING SFP MODULE’S CONNECTORS, AS EYE DAMAGE MAY RESULT.

The SFP module is sensitive to electrostatic discharge (ESD). It is recommended that you use an ESD­preventive wrist strap grounded to the Densité chassis while handling the SFP module.

SFP modules are subject to wear, and their useful lifetime is reduced each time they are inserted or removed.
Do not remove them more often than is absolutely necessary.

Never remove or install an SFP module with the fiber optic cables connected. Damage to the cables could

Installing an SFP module

result.

The presence of dust and debris can seriously degrade the performance of an optical interface. It is
recommended that you insert a dust plug into the SFP module whenever a fiber optic cable is not connected.

1. Make sure that the bale clasp lever is in the closed position

2. Position the SFP module so that the recessed slot is lined up with the
tab side of the socket.

42 | ADX-1901

GUIDE TO INSTALLATION AND OPERATION

3. Slide the module straight into the socket, and push gently until it

clicks into position.

Connecting the fiber optic cables

1. Remove the dust plug from the SFP module if present

2. Verify that the exposed end of the optical fiber in the LC

connector is clean

• Carefully remove any debris if necessary.

3. Plug the LC-terminated fiber optic cable into the SFP module

Removing the fiber optic cables

1. Grasp the LC fiber optic connector that is plugged into the SFP module, and pull it straight out to disengage

the optical fiber from the SFP.

• Never pull the fiber optic cable itself, as catastrophic damage may occur.

2. Insert a dust plug into the SFP module.

Removing the SFP module

1. Move the bale clasp lever to the open position.

2. Grasp the SFP module between your thumb and forefinger, and

pull it straight out of the slot.

• Do NOT pull on the bale clasp lever to remove the module, as
it is easily damaged

• You may find that you need to wiggle the module, or perhaps
push it into the slot a bit, before it will release and slide out.

3. Insert a dust plug into the SFP module.
