Installation

Installation

The 8943FC model consists of a front and rear module set that can only be
installed in a GeckoFlex frame. Two fiber optic dual transmitter SFP device
kits, shipped separately, must also be installed for full functionality of the
module.

Installation of the 8943FC module set is a process of:

1. Placing the 8943FC-R rear module in a rear frame slot,

2. Installing the fiber optic SFP devices on the front module,

3. Placing the front module in the corresponding front slot,

4. Cabling the signal ports, and

5. Setting module parameters with on-board switches or with the web

browser interface.

All GeckoFlex front and rear modules can be inserted and removed from
an GeckoFlex frame with power on.

Note Modules and SFP devices are sensitive to static damage, use standard anti-

static precautions when handling components.

Module Placement in the GeckoFlex Frame

There are ten front and rear cell locations in the 2 RU GeckoFlex frame

Figure 1) to accommodate either audio, analog and digital video modules.

8943FC — Instruction Manual 11

Installation

Module Installation Precautions

Please read and follow the precautions listed below before installing the
front and rear modules and any optional fiber optic SFP devices:

• Use standard anti-static procedures during installation. As modules
can be installed or removed when the GeckoFlex frame is powered up,
before removing the cover, please use an anti-static bracelet tied to a
metal part of the frame.

• Install the rear module first, then install the option fiber optic SFP
devices on the front module, then install the front module.

• When installing or removing a rear module, loosen or tighten the
screws holding the retainer clips to the frame manually with the
retainer clip tool provided inside the front cover of the frame or use a
2 mm (5/64”) hex screwdriver. Please do not use an electric screw­driver.

Note On newer 751- version GeckoFlex frames, a Rear Retainer Clip removal tool

and 2 extra retainer clips and screws for installing them are provided on the
inside of the frame cover.

• Make every effort to leave the screws holding the retainer clips in place
(do not remove them completely). They are very small and can easily
drop into other equipment causing a shorting hazard. (Two turns of the
screw should be enough to loosen the screws, 3 turns or more will
remove it.)

• When installing a rear module, tighten the screws on the retainer clips
just until snug. Do not apply more force than is necessary to seat the
rear module. Refer to the

page 53.

• If using a fiber optic SFP device on the fiber-ready front module, handle
it carefully, use anti-static precautions, and read the Installation on

page 11 before cabling.

Mechanical specifications given in Tab le 6 on

Rear Module Installation

8771_07r0

Use retainer clip or
needlenose pliers
to pull out blank after
removing retainer clips

To install the rear module, refer to Figure 2 and the instructions below:

1. To remove a blank rear adapter cover (or a rear module already

present), manually loosen the two screws holding each retainer clip on
the rear adapter cover or rear module to the frame with the retainer clip
tool provided inside the front cover of the frame (newer model frames
only) or a 2 mm (5/64”) hex screwdriver. Do not remove the screws.

Note To remove a rear module already installed, follow the same steps. It is helpful

to first remove the front module so the rear can be pulled out more easily.

2. After loosening the retainer clip screws, pull up on each retainer and

completely remove it, leaving the screws in place.

3. Remove the blank rear adapter cover by inserting needlenose pliers

into the slots in the blank cover and pulling it off.

4. Insert the rear module into the empty slot, guiding it carefully.

5. Replace each retainer clip over the two screws on both sides of the

module and push down to seat the retainer clip.

Installation

6. Tighten the two screws on each retainer clip just until they come into

contract with the retainer clip then tighten about a 1/4 turn more
(maximum torque is 4-5 inch-lb/0.45-0.6Nm). Do not force or torque
the screws too tightly. The clips should not bend or be bowed.

Note All unused rear slots in a GeckoFlex frame should have a blank rear adapter

cover installed.

Attenuation Requirements

Some shorter length cable runs will require attenuation to prevent over­driving the receiver causing bit errors to occur on the fiber link. Use the fol­lowing guidelines for adding attenuation:

• The 1310nm Dual Transmitter (SFP-13103G-M1DTX) requires no atten-

uation between fiber transmitter and receiver connections at any cable
lengths.

• CWDM devices used with 8939FCA modules for a mux/demux config-

uration (page 28) with a cable run from 0-12 km (7.5 miles), must be
attenuated by 3 dB between 8939FCA COM ports.

• All CWDM devices used in a point-to-point configuration with a cable

run from 0-20 km (12.4 miles), must be attenuated by 5 dB between
fiber transmitter and receiver connections.

The 8943FC module can be used for CWDM (Coarse Wavelength Division
Multiplexing) in various configurations in conjunction with 8939FCA and
8939FCB modules and 8943CF modules as well as other fiber-ready
modules from Grass Valley. Two main examples are given in this manual.

CWDM Configuration for 9 Channels

One use of CWDM involves the ability to multiplex and demultiplex up to
9 channels of video in as shown in the simple block diagram in

Figure 20. Simple CWDM Block Diagram

Installation

Figure 20.

When an 8943FC module is populated with CWDM SFP devices, a stan­dard crossing duplex cable is required when connecting the 8943FC
modules to the 8939FCA modules.

Crossing is in reference to the logical A/B nomenclature associated with
the duplex connector illustrated in
side 2B and side 1B connects to side 2A.

Figure 21. Standard Crossing Duplex Fiber Cable

Figure 21 where side 1A connects to

8943FC — Instruction Manual 25

Installation

To utilize this 9 channel Mux/Demux application, the following Grass
Valley modules are needed:

• Two 8943CF 4 Channel Electrical to Fiber Converter modules with one
of each type of CWDM SFP device

• Two 8943FC 4 Channel Fiber to Electrical Converter modules with one
of each type of CWDM SFP device

• Two fiber-ready Grass Valley GeckoFlex modules with 1310nm SFP
devices

As shown in the detailed block diagram in Figure 22 on page 27, two
8943CF (Electrical to Fiber converters) at Location A are used to feed 8
channels of video to an 8939FCA. To utilize this application, one of each of
the following four CWDM SFP device types must be installed on the two
8943CF modules:

• SFP-CWDM3G-1-K Dual Transmitter (1470nm/1490nm frequencies)

• SFP-CWDM3G-2-K Dual Transmitter (1510nm/1530nm frequencies)

• SFP-CWDM3G-3-K Dual Transmitter (1550nm/1570nm frequencies)

• SFP-CWDM3G-4-K Dual Transmitter (1590nm/1610nm frequencies)

Note The four SFP devices can be installed in any location on the two 8943CF

modules as long as the outputs are cabled to the correct frequency input on
the 8943FCA. The installation configuration shown here is for clarity only.

The 1310nm fiber output from a Grass Valley GeckoFlex module is cabled
to the EXP (Expansion) port on the 8939FCA.

The 8939FCA module multiplexes these 9 frequencies down to a single
output from the COM port. A single fiber cable carries these 9 video fiber
channels to the COM port of the 8939FCA at Location B.

The 8939FCA at Location B acts as a demultiplexer and outputs 9 fiber
video channels to two 8943FC (fiber to electrical) modules, each with two
SFP-13103G-M1DRX-K Dual Receiver SFP devices installed and a Grass
Valley fiber-ready module. The dual receiver SFP device will accept input
frequencies from 1270nm to 1610nm.

Refer to Attenuation Requirements on page 23 concerning the attenuation
needed depending on the length of cable run between 8939FCA COM
ports.

Configuration and Monitoring

8943FC module configuration and monitoring can be performed locally
using the onboard controls or using a web browser GUI interface when the
8900NET Network Interface module is present in the GeckoFlex frame.
Control and monitoring is described in the following sections:

• Input Operating Modes Overview – page 31

• Local Configuration and Monitoring – page 34

• Remote Configuration and Monitoring – page 39

Input Operating Modes Overview

Each of the four channels must be configured for the desired operating
mode. This can be done using the onboard switches or on the Settings web
page using the web browser interface. The five different modes of opera
tion are described in this section. Input signal monitoring differs between

Remote Monitoring and Controls

The 8943FC module can be configured and monitored remotely when an
8900NET module is installed in the GeckoFlex frame using the web-based
GUI or the Newton Control Panel.

8900NET Module Information

Refer to the 8900NET Network Interface Module Instruction Manual for infor­mation on the 8900NET Network Interface module and setting up and
operating the GeckoFlex frame network.

Note The 8900NET module in the GeckoFlex frame must be running software

version 4.0.2 or higher for proper remote and control panel operation.
Upgrade software and instructions for the 8900NET can be downloaded from
the Grass Valley web site.

ftp://ftp.grassvalley.com/modular/8900/8900net/v4.3.0/

Configuration and Monitoring

Newton Control Panel Configuration

A Newton Control Panel (hard and/or soft version) can be interfaced to the
GeckoFlex frame over the local network when the 8900NET (Net Card) is
present. Refer to the documentation that accompanies the Newton
Modular Control System for installation, configuration, and operation.

Control panel access offers the following considerations for module config­uration and monitoring:

• Ability to separate system level tasks from operation ones, minimizing
the potential for on-air mistakes.

• Ability to group modular products—regardless of their physical loca­tions—into logical groups (channels) that you can easily manipulate
with user-configured knobs.

• Update software for applicable modules and assign frame and panel IP
addresses with the NetConfig Networking application.

• Recommended for real-time control of module configuration parame­ters, providing the fastest response time.

Note All module functions may not be available with the control panel.

Web Browser Interface

The web browser interface provides a graphical representation of module
configuration and monitoring.

Use of the web interface offers the following considerations (when appli­cable for the module):

• Provides complete access to all module status and configuration func­tions, including factory parameter default recalls, slot configuration,
and SNMP monitoring controls.

• Web access will require some normal network time delays for pro­cessing of information.

• Configuration parameter changes may require pressing

Enter, upload processing time, and a manual screen refresh to become

effective.

• Web interface recommended for setting up module and reporting
status for SNMP and monitoring.

Status Monitoring

There are a number of ways to monitor frame and module status. These
methods are summarized here. For more detailed information, refer to the

8900NET (Net Card) Network Interface Module Instruction Manual and the
8900 Gecko or 8900 GeckoFlex Frame Instruction Manuals.

All modular product documentation is available on-line in PDF format at
this link:

www.grassvalley.com/docs/modular

The main status monitoring methods include the following:

• External frame alarm output on the rear of the 8900 frame with

• LEDs on the Frame, 8900NET module, and individual frame media

• Web browser status reporting for each frame component, and

reporting from the Module Health Bus and other frame status alarm
reports,

modules,

• SNMP traps, captured by Grass Valley’s NetCentral or another SNMP

Manager Application.

Note SNMP trap information is only available when an SNMP Agent has been

installed and configured.

External Frame Alarm

An external Frame Alarm output is available on pins 8 and 9 of the RS-232
connector on the rear of the frame. The Frame Alarm outputs a voltage
level indicating there is an alarm condition on the Module Health Bus or
one of the other frame components reported to the Frame Monitor module
in a Gecko 8900TF or GeckoFlex 8900FF frame or the 8900NET module in
an 8900TFN and GeckoFlex 8900FFN frame.

• The Module Health bus is a separate line on the frame motherboard

that provides a means for older or less capable modules (such as DAs
with no microprocessor) that cannot communicate over the Frame
(serial) bus to report warning and alarm conditions to the external
Frame Alarm. All media modules in the frame report a voltage level to
this line when a warning condition occurs on the module. The specific
warning or module location is not reported, only an indication that an
warning condition has occurred.

• Frame alarm reporting from other frame components can be enabled

and disabled using DIP switches on the Frame Monitor and 8900NET
module. For frames with an 8900NET module, the Frame Alarm
Reporting web page allows configuration of the alarms and warnings
that are reported to this external Frame Health Alarm.

LED Reporting

Web Browser Interface

LEDs on the front of media modules, the Frame Monitor or 8900NET mod­ules, and the front covers of the 8900TF/TFN and GeckoFlex FF/FFN
frames indicate status of the frame and the installed power supplies, fans
in the front covers, and module status. (The 8900TX-V/A and GeckoFlex
8900FX frames have no LED indicators on the front cover.)

• LED reporting from the modules in the frame to the 8900NET module
is configurable using the 8900NET LED Reporting web page.

• The Status LEDs for this module are described in Local On-board Status

Monitoring LEDs on page 34. LEDs for the 8900NET module are

described in the 8900NET (Net Card) Network Interface Instruction

If the module has not passed self-diagnostics, do not attempt to trouble­shoot. Return the unit to Grass Valley Customer Service (see Module Repair).

Electronic Circuit Breaker

An electronic circuit breaker on the module works during a fault condition
or an overcurrent to cut off power to the module in place of a fuse.

If power has been cut off to module, remove the module and replace it in
the frame to reset. If the problem persists contact Grass Valley Customer
Service.

Module Repair

If the module is still not operating correctly, replace it with a known good
spare and return the faulty module to a designated Grass Valley repair
depot. Call your Grass Valley Customer Service representative for depot
locations.

Refer to Contacting Grass Valley on page 4 at the front of this document for
the Grass Valley Customer Service contact information.
