8972PX HD/SD/DVB ASI Protection Switch Module

Introduction

This manual covers installation, configuration, and operation of the 8972PX HD/SD/DVB ASI Protection Switch module for the GeckoFlex frame.

The 8972PX module is a signal protection switch designed to maintain a continuous Program video output. Two relay-protected input signals, called the Primary and the Secondary, are part of a changeover switch that continuously feeds the Program Output with a good signal. In addition, an Alternate input signal (not relay-protected) can be enabled to provide another backup candidate signal if desired. The module accepts HD/SDSDI, or DVB ASI video signals.

The switching of the input signal to maintain a continuous protected Program Output can be manually controlled by the user with various manual switching controls, including an external GPI interface. The module can also be set in user configuration to switch autonomously by the module according to the status of defined signal criteria. When switching is controlled autonomously by the module, it will automatically switch the Program Output to the next valid backup candidate depending on whether the user favors to maintain the Primary input or maintain stability of the Program Output signal.

The module can maintain the Program Output even in the event of a power failure or when the front module is completely removed from the frame. This is done by the presence of relay-controlled passive bypass circuitry on the rear module that latches the relay-protected Primary or Secondary input signal to the Relay-Protected Program Output BNC.

The 8972PX can be used in play-out and transmission applications where switching between main and redundant paths is required. Another useful application is for switching between alternate inputs (Please Stand By apology slides for example) when the primary and secondary have both failed.

8972PX — Instruction Manual 9

System Requirements

The main features of this module are summarized below:

• Two module set including a hot-swappable front and dual rear module.

• Two relay-protected changeover input signals, the Primary and the Secondary, continuously feed a relay-protected Program output,

• An Alternate input is also available as a backup candidate.

• Passive Bypass Only mode to maintain signal path in the event of power failure and for maintenance purposes.

• Eight outputs, including:

• One main relay-protected output with passive bypass feature.

• One electronic output that follows the main input.

• Three output pairs that can be user-configured to follow one of five

choices: Program, Backup Candidate, Primary Input, Secondary Input, or Alternate Input inputs.

• Manual switching controls including a GPI interface, web pages, Newton Control Panel, front edge pushbuttons, and SNMP commands,

• An Autonomous mode that can be set in module configuration to switch the input to the Program Output based on signal health status

Good or Not Good) of the HD, SD or DVB ASI signal inputs.

(

• Module configuration can be done with the web pages or using the Newton Control Panel.

• Autonomous module control can be overridden by using any manual switching control.

• SNMP health monitoring is supported through the 8900NET module with applications such as NetCentral.

• Software updating using NetConfig or an microSD card.

System Requirements

8972PX module operation requires the presence of an 8900NET Network Interface module in a GeckoFlex frame running software version 4.2.0 or later for configuration. The latest version is recommended. Check the soft ware version of your 8900NET (Net Card) Network Interface module by navigating to the Frame Status web page (see example) and noting the software version given below the frame graphic.

Figure 17 on page 45 for an

The latest 8900NET module software as of this printing is version 4.3.0 and can be downloaded free of charge directly from the Grass Valley ftp site at this location:

Configuration Summary

This section of the manual gives a summary of the available switching strategies, how they are configured, and how the module can be manually controlled by the user.

The input selection to the Program Output can be switched using manual switching controls at any time by the user or set to switch automatically by the module’s own autonomous switching strategy mechanism based on the signal health status of the Primary, Secondary, and (if enabled for use in autonomous mode), the Alternate input, as determined by the module.

The manual switching controls include the GPI interface, the web page controls, the Newton Control Panel, the hardware pushbutton switches on the front edge of the module circuit board, and the SNMP commands. Refer to

Manual Switching Controls on page 13 for a complete overview of the

manual switching controls.

When the module is set to operate in an autonomous mode (under control of the module), the type of switching is selected in configuration as one of two switching strategies:

Configuration Summary

• Maintain Stability – using this strategy, the autonomous control favors

stability on the Program Output and it keeps either the Primary or Secondary input as the Program output as long as their signals remain good.

• Maintain Primary – using this strategy, the autonomous control favors

maintaining the Primary input as the Program Output. If the module has detected the Primary as not good, it switches to the Secondary. The module switches back to the Primary input whenever the Primary is detected as good. The amount of time before the Primary switches back after being detected as good (Switchback Delay) can be set by the user.

For an overview of the Autonomous mode of operation, refer to Autono-

mous Mode on page 16.

The current Program Output set by the module while in Autonomous mode can be overridden at any time by the user with a manual switching control. When this occurs, the switching mode of the module changes to

Manual. To put the module back into the Autonomous switching mode

(Maintain Primary or Maintain Stability), the user must configure this setting using the remote controls (Output Control web page, the Newton Control Panel, or the SNMP get/set commands).

An understanding of the switching override priorities can be helpful in using the 8972PX module. As shown in

Figure 1, the GPI interface will have

highest priority over other manual switching controls and the autonomous control modes.

Activating the GPI interface by making contact closure with the Switch to Primary, Switch to Secondary, or Switch to Alternate GPI lines will force the Program Output to the selected choice. When this GPI line is de-activated, the module is left in Manual mode and the Program Output can be switched using any of the manual switching controls or the module can be set to Autonomous mode using the Output Control web page, the Newton Control Panel, or the SNMP get/set controls.

Note When the GPI Exclusive Control is activated by contact closure, only the GPI

switch controls (Switch to Primary, Switch to Secondary, or Switch to Alternate) can be used to change the input choice to the Program Output, leaving the module in Manual mode. Once all GPI closures are de-activated, the module can be controlled using any manual switch controls or be configured for autonomous control.

GPI Program Output Controls and Monitoring

The Program Output selection can be controlled through the SubD-25 GPI I/O connection mounted on the rear module when wired to an external customer-supplied GPI control device. Switching is activated by contact closure. The GPI controls work directly on the front module to select the Program Output. Primary, Secondary, and Alternate input signal status can also be reported to the GPI interface through tally connections.

Configuration Summary

The four switching control lines from the customer-supplied device and the six input status reporting lines from the front module are shown in

Figure 2.

Figure 2. GPI Interface

8972PX — Instruction Manual 13

Configuration Summary

When the GPI Exclusive Control line is activated by contact closure, only the Switch to Primary, Switch to Secondary, or Switch to Alternate GPI control lines can be used to change the designated input selection (by contact closure). The Program Output selection will be under control of the GPI Switch commands until the GPI Exclusive Control is de-activated leaving the module in Manual mode. At this point, the user may use another manual switching control to change the input to the Program Output or set the module to an Autonomous switching strategy.

It is not necessary to activate the GPI Exclusive Control to drive the module with a GPI control. Any one of the three GPI controls (Switch to Primary, Switch to Secondary, or Switch to Alternate) can be activated indepen dently by contact closure forcing the Program Output to the designated input. This also switches the module to Manual mode. The selection of the Program Output will remain under GPI control only as long as one of these three GPI controls is activated (by a contact closure).

While the Program Output selection is under GPI control, the web pages will display a message stating

Figure 27 on page 64). Once GPI control is removed (no contact closure

(see on any of the four GPI controls), the module is in Manual mode. The user can then control the module with any of the manual switching controls (see

Manual Switching Controls on page 13) or set the module to an Autonomous

switch mode (Maintain Primary or Maintain Stability).

The GPI is controlling the Program Output Selection

Web Page Control

The Program Output can be forced manually using the Output Control web

page 62) by selecting the Force Primary, Force Secondary, or Force Alternate

page ( buttons in the Program Output Selection section,. This will change the Switching Strategy Switch mode to the page.

Newton Control Panel

The Newton Control Panel command PrgOutput allows manual selection of the Primary, Secondary, or Alternate output and forces the Program output to this selection. For a summary of all Newton Control Panel parameters, refer to the

Summary of 8972PX Configuration Functions on page 83.

SNMP Commands

In addition to the standard 8900 module SNMP monitoring reporting, the 8972PX module allows two get/set commands to manually manage the input selection (Input Select) and module mode of operation (Switchback Strategy) through the SNMP interface. Refer to

Commands on page 80 for details.

Configuration Summary

Autonomous Mode

When the module Switching Strategy is set for an autonomous mode, the module automatically determines signal status based on enabled signal health criteria as interpreted by the module for the three video inputs, Pri mary, Secondary, and Alternate (when selected for usage in Autonomous mode on the System Config web page). Refer to the block diagram in

Figure 4 on page 19 for an overview of the Autonomous mode.

There are two switching strategies in the Autonomous mode: Maintain Stability and Maintain Primary. One of these must be selected as the Switch Mode for use in the Autonomous mode using one of the remote controls (Output Control web page, Newton Control Panel, or SNMP get/set com mands).

• Maintain Stability Mode – in situations where signal stability on the

program Output is most important, select this mode. When the Primary has failed and has switched to the Secondary, it will stay on the selected Secondary until forced back to the Primary manually or the Secondary fails. This mode provides the least amount of signal interruption (the most signal stability).

•

Maintain Primary Mode – in situations where it is favored to have the

Primary input active as much as possible, select this mode. When the Primary has failed and has switched to the backup candidate, when the Primary has recovered, the module automatically returns the Primary to the Program Output. The switchback to the Primary can be set to a delay to allow the restored signal to establish itself after recovery. The amount of Program Switchback Delay is set by the user on the Output Control web page or using the Newton Control Panel.

Signal Health Criteria

Signal health status for the three input signals is determined by certain criteria analyzed by the module. The 8972PX handles HD/SD SDI video signals or DVB ASI signals and uses different criteria to determine signal health status. The status of the module inputs (when the I/O Config web page for each input signal) is given on every web page in the header area at the top of the page and also reported on the Newton Control Panel and can be read from the GPI interface.

The input format to the module can be selected as Auto allowing all of the signal standards in the Input Standard Selection pulldown (on the

Config Web Page on page 55) to be considered valid by the module for any

input. If only a single standard is selected as the input format, only that standard will be considered valid for any input to the module.

Configuration Summary

HD/SD Criteria

When the input signal is HD or SD SDI video, the signal health status is based on the following criteria as analyzed by the module. These criteria are always enabled and the module will determine module health by checking each item below.

The signal is considered Good when:

• Carrier Detect – a valid carrier is detected on the input,

• Serial Lock – the serial receiver is locked to a SMPTE compliant data stream,

• Valid Format – the input signal matches the selected input selection,

• SMPTE Presence – no instability has been detected for a valid format, and

• No SMPTE TRS Errors – no TRS (Timing Reference Signal) errors have been detected.

If any one of these criteria are incorrect for the input type selected, the signal will be reported as occur depending on the Switching Strategy Switch Mode selected in con figuration:

Not Good. When this happens, the following cases

• If the Switchback Strategy Switch Mode is set for Maintain Primary, the module will switch the Program Output immediately to the Backup Candidate. It will return the Primary input to the Program Output as soon as the Primary input becomes good again in the time set with the Switchback Delay control on the Output Control web page or with the Newton Control Panel.

• If the Switchback Strategy Switch Mode is set for the Primary input is detected as Program Output immediately to the next valid Backup Candidate and remain there until the user decides to manually override the selection to return the Primary input to the Program output or the Backup Candidate fails.

An optional criteria category to check for EDH/CRC errors can be enabled by checking the EDH/CRC

DVB ASI Criteria

When the input signal is DVB ASI, the signal health status is based on the criteria described below as determined by the module. These criteria are always enabled and the module will determine module health by checking each item below.

The signal is considered Good when:

• Carrier Detect – a valid carrier is detected on the input,

• Serial Lock – the serial receiver is locked to a DVB ASI compliant data stream,

• Valid Format – the input signal matches the selected input selection, and

• MPEG2 TS Lock – the input signal is locked to the synchronization byte of the MPEG packets.

If any one of the criteria are incorrect for the input type selected, the signal will be reported as the same as the HD/SD SDI video signals explained in

page 17.

Not Good. Switchback Strategy Switch Mode selection is

HD/SD Criteria on

On each input link, the bit rate of packets is evaluated on up to 4 userdefined PIDs (the minimum bit rate detected is one packet per second or

kbps). A PID is seen as not present as soon as there is no packet within

1.5

one second. It is recommended to choose PIDs whose bit rate is at least 4.5 kbps to avoid an unexpected switch of the input if packets are not evenly spaced on the transport stream. Primary and Secondary inputs share the same PIDs. The Alternate input can have 4 independent dedicated PIDs.

For setting the PIDs, see DVB/ASI Criteria Web Page on page 60. Presence and Continuity Error reporting criteria can also be enabled as desired for each PID stream.

Switching Summary Tables

To aid in understanding the detailed processing behavior in the various states of the module inputs, a number of switching summary tables are pro vided in the next section. Use these tables along with the following three basic rules for autonomous switching of inputs to the Program output to better understand processing behavior:

1. The module always selects the Primary or Secondary inputs (when

valid) over the Alternate input.

2. In the Maintain Primary autonomous mode, the module always selects

the Primary input when it is valid.

3. In the Maintain Stability autonomous mode, the module always selects

the valid input that reduces the amount of switching. If it switches from the Primary to the Secondary, it will leave the Secondary as the Program output until the Secondary fails.

Ta bl e 1 through Tab le 5 present a detailed description of the next Program

output/Backup Candidate state by giving each possible case for the current state of the Program output and the Backup Candidate using the Primary, Secondary, and Alternate inputs and other configuration factors.

Configuration Summary

Passive Bypass Only Mode

The Passive Bypass Only mode has two main purposes as described below:

1. During normal operation, the Bypass mode for the module is set for

Active Processing Enabled on the System Config web page. The module can

be set for that occurs when power is lost or the front module is removed. The

Passive Bypass Only mode is normally used for maintenance purposes

such as cabling or testing the rear module relay bypass path.

When set for Passive Bypass Only, the module simulates the bypass state where the Primary and Secondary inputs are switched by relays on the rear module to the Relay-Protected Program Output at BNC, J7 as shown in signals now bypass the front module completely and the Status of the Primary and Secondary inputs on all web page headers are reported as

Bypassed as shown in the example in (Figure 22 on page 56). As this

mode is only a simulation of removing the front module, putting the module in this mode does not affect the other controls on the front module or the Alternate input.

Passive Bypass Only to simulate the relay-protected bypass state

Figure 5 on page 27. The Primary and Secondary input

In this mode, output J7 (Relay-Protected Program Output), remains the input previously selected (except if it was the Alternate input it will be switched to the Primary input). When the module is switched back to

Active Processing Enabled on the System Config web page, it returns in

Manual mode with no change to the Program Output.

2. When power is lost to the frame or the front module is completely

removed, the relay-protected Primary and Secondary inputs will automatically be switched to the rear module relay bypass path and the input previously selected will be latched to the output at BNC J7, the Relay-Protected Program Output. The passive bypass path ensures the continuous transmission of the Primary/Secondary input signal to the Relay-Protected Program Output. When power is returned to the frame or the module is reinserted, the module will be in Manual mode with no change to the Program Output.

Installation

Module Placement in the GeckoFlex Frame

The 8972PX model consists of a front and dual rear module set that can only be installed in a GeckoFlex frame.

Installation of the 8972PX module set is a process of:

1. Placing the 8900PX-DR dual rear module in a rear frame slot (this rear

module requires two adjacent rear slot spaces and cannot be installed in Slot 10),

2. Placing the front module in the corresponding front slot

(corresponding to the module connector on the rear module), and

3. Cabling the signal ports.

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

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

Figure 6) to accommodate either audio, analog and digital video modules.

( The 8972PX module set uses the 8900PX-DR rear module that requires two adjacent slots, allowing up to five 8972PX modules per frame.

Figure 6. GeckoFlex Frame

28 8972PX — Instruction Manual

Module Installation Precautions

Please read and follow the precautions listed below before installing the front and rear modules:

• 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 or heel strap tied to a metal part of the frame.

• Install the rear module first, then 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.

Installation

• 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. The recommended torque specification is 4-5 inch-lbs/0.45-0.6Nm.

8972PX — Instruction Manual 29

Installation

Use needlenose pliers to pull out blank after removing retainer clips.

Rear Module Installation

Each 8900PX-DR rear module requires two adjacent rear frame slots, so the front module cannot be installed in slot 10 of the frame. Each rear module or blank rear adapter cover is held in place by two retainer clips as shown in

Figure 7. To install a rear module into the frame, follow these steps:

1. Loosen (but do not remove completely) the two screws holding each

retainer clip to the frame with a 2 mm (5/64”) hex screwdriver. Pull up on the retainer clip to remove it, leaving the screws in place.

CAUTION Be careful to leave the screws in place as they can be easily lost or fall into

equipment below the frame creating a shorting hazard.

2. Remove the blank rear adapter covers on two adjacent slots by inserting

needlenose pliers into the slots in the top and bottom of the blank and pulling it off.

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.

3. Insert the rear module into the empty slots.

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

module and push down to seat the retainer.

5. Tighten the screws for each retainer clip just until they are snug. Do not

force or torque the screws too tightly.

Output pairs Output 1.1 and 1.2, Output 2.1 and 2.1, and Output 3.1 and 3.2 are user-configurable to output different signals as desired. For configura tion information, refer to Configuration Summary on page 11.

Before cabling the module, read the following section on determining cable length.

Determining Maximum Cable Length

To maintain the quality of the Program Output signal when the front module is bypassed in the case of loss of power or front module removal, the total cable length must be determined in Passive Bypass mode. The total cable length is defined as the addition of the cable length from the signal source to the 8972PX Primary (J9) or Secondary input (J10) plus the cable length from the 8972PX output BNC J7 to the destination equipment as shown in in SD and 100m in HD. Refer to Tab le 9 on page 71 for a list of specifications.

When cabling the module, you can test cable length and the quality of the bypassed Program Output signal by setting the Bypass Mode on the System Config web page to Passive Bypass Only (see the module and monitoring the Program Output signal on J7 (Relay-Protected Program Output).

Figure 9. This cable length is specified as no more than 300m

Installation

Relay-Protected Program Output

The Relay-Protected Program Output at BNC J7 is the main Program Output for the module. It wired to the relay-protected passive bypass cir cuitry on the rear module which includes the Primary and Secondary inputs as part of the relay path, assuring a continuous output source. Refer to

Passive Bypass Only Mode on page 26 for an explanation of the bypass

mode.

Note To assure the bypassed Program Output signal meets the correct specifica-

tions, read the section on determining cable length in Determining Maximum

Cable Length on page 32.

Program Output

The Program Output at BNC J5 outputs the current Program Output signal from BNC J7, the Relay-Protected Program output, when the module is not in bypass mode. In bypass mode, the output at J5 is not active.

Outputs 1.1 and 1.2, Outputs 2.1 and 2.2, Outputs 3.1 and 3.2

Three sets of programmable output pairs (Outputs 1.1 and 1.2, Outputs 2.1 and 2.2 and Outputs 3.1 and 3.2) can be configured to output the Program, Backup Candidate, Primary Input, Secondary Input, or Alternate Input signal as desired. Programming of these output pairs is done on the Output Control web page ( Newton Control Panel (see Tab le 12 on page 83).

GPI I/O Connector

The Program Output from the front module can be controlled and monitored through the SubD-25 GPI I/O connector on the rear module using an external customer-supplied GPI interface. Due to the densely populated rear module, a custom designed optional SubD-25 connector (8900PX-DBS) is available from the factory in order to allow space for using a trumpeter tool for connecting signals to adjacent BNCs (see

Option on page 35).

For using a standard SubD-25 connector, the following maximum dimensions are recommended:

• Maximum width of 15 mm

• Maximum length of 57 mm

GPI I/O Control Interface

The GPI I/O connector inputs provide a means to enable (Force) the Primary, Secondary, or Alternate input signal to become the Program Output. The inputs are suitable for a connection to a relay contact (switch button) or to an open collector output in a typical circuit.

When the GPI Exclusive Control is activated, the Program Output can only be changed using one of the Switch to Primary, Switch to Secondary, or Switch to Alternate GPI controls until all GPI controls are de-activated.

To activate a GPI In function, a switch closure must be provided between the GPI In common ground (pin 13) and the GPI In function for a minimum of 80ms. To change states (deactivate the selected input) the contact closure must be open for at least an 80ms duration.

Refer to Tab le 7 on page 35 for a complete list of the GPI I/O function pin numbers. An example of a GPI interface using relay contacts is shown in

Figure 12. A typical Open Collector example is shown in Figure 13 on page 38.

Note Use either Open Collector or relay (switch button) controls but not both

methods in the same GPI interface configuration.

GPI Relay Status Monitoring

The rear module GPI I/O connector also provides tally connections to report to the external GPI device the input signal status of what input signal is currently on the Program output and if any of the input signals have failed. The Program output active and failure reporting status of the Pri mary, Secondary, and Alternate inputs can be monitored by the GPI device.

The solid state relays are bi-directional; either polarity voltage can be applied. It can be used to drive downstream DC relays. Each tally output is active on a steady closure state.

Examples are given in Figure 14 on page 40 for both logic connections and 12V lamps to an external system. Refer to Tab le 7 on page 35 for a complete list of GPI function pin numbers.

Relay outputs specifications are maximum current of 0.5A (continuous) or

Power Up

The front LED indicators and configuration switches are illustrated in

Figure 15. Upon power-up, the green PWR LED should light and the

yellow CONF LED should illuminate for a few seconds for the duration of module initialization.

Note When a media module is first plugged into a GeckoFlex frame, the 8900NET

module (if present) may report a momentary fault. This will clear once the media module has booted up.

With factory default configuration and valid Primary, Secondary and Alternate input signals connected, the PWR LED, the SEL LED indicating the active Program output source, and the PRES LEDs for valid input signals on the top side of the module front edge should illuminate ( Refer to Tab le 8 on page 42 to see the operating indicator combinations.

Figure 15).

Local/Remote Jumper

The on-board Local/Remote jumper, J8, (Figure 15) is set by default at the factory to the LOC/REM position (pins 1-2). This setting allows access to both the local and remote controls. Remote controls include the web inter face, Newton Control Panel, and SNMP commands used for setting module configuration parameters. It is possible to lock out remote controls by moving the jumper to Local control only (LOC position, pins 2-3).

Module Configuration and Monitoring

Configuration

The 8972PX module configuration operating parameters are set using the web pages and the Newton Control Panel which require the presence of the 8900NET (Net Card) Network Interface module.

Refer to the following sections for configuration instructions:

• Module Configuration and Monitoring (below)

• Configuration Summary Table (page 83)

8972PX module configuration and monitoring is performed using a web browser GUI interface or a networked Newton Control Panel when the 8900NET Network Interface module is present in the GeckoFlex frame. Each of these interfaces is described below. In addition, monitoring of signal status can be done with the GPI interface and an SNMP application.

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 4.2.0 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. See System Requirements on page 10.

Newton Control Panel Configuration

A Newton Control Panel (hard and/or soft version) can be interfaced to the GeckoFlex frame over the local network. Refer to the documentation that accompanies the Newton Modular Control System for installation, config uration, and operation information.

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.

8972PX — Instruction Manual 43

Configuration

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

Note Not all module functions are available with the control panel, such as E-MEM

and factory default recalls. The available control panel controls for the 8972PX module are listed in Table 12 on page 83.

An example of the Newton Configurator is shown in Figure 16.

Figure 16. Newton Configurator Example

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:

• Provides complete access to all module status and configuration functions, including naming of inputs and outputs, factory parameter and name default recalls, E-MEM functions, 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

Status Monitoring Summary

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

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

• Web browser status reporting for each frame component, and

Status Monitoring Summary

• 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 activates a contact closure when there is an alarm condition on the Module Health Bus or one of the other frame components as 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.

8972PX — Instruction Manual 73

Status Monitoring Summary

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. LEDs for the 8900NET module are described in the 8900NET (Net Card) Network Interface

Instruction Manual

The Status LEDs for this module are described in Operation Indicator LEDs

on page 41.

The 8900NET module required in the frame for the 8972PX module controls a web browser GUI that indicates frame and module status on the fol lowing web pages:

• Frame Status web page – reports overall frame and module status in colored graphical and text formats. Refer to Figure 17 on page 45 for an example.

•Module Status web page (Figure 19 on page 51) – shows specific input and reference signal configuration error status to the module along with module status and information (part number, serial number, hardware version, software/firmware/boot versions, and Asset number (as assigned on the Slot Config web page).

• A Status LED icon on each web page reflects the module status on the module Status web page where warnings and faults are displayed and is a link to the module Status web page.

GPI Interface Status Reporting

On the 8972PX module, the GPI interface can also report the status of the Primary, Secondary, and Alternate inputs. Refer to

toring on page 39 for using this interface.

SNMP Reporting

GPI Relay Status Moni-

The Gecko 8900 Series system uses the Simple Network Monitoring Protocol (SNMP) internet standard for reporting status information to remote monitoring stations. When SNMP Agent software is installed on the 8900NET module, enabled status reports are sent to an SNMP Manager such as the Grass Valley’s NetCentral application.

Service

Power-up Diagnostics Failure

Service

Status reporting for the frame is enabled or disabled with the configuration DIP switches on the 8900NET module. Most module status reporting items can be enabled or disabled on individual configuration web pages.

The 8972PX modules make extensive use of surface-mount technology and programmed parts to achieve compact size and adherence to demanding technical specifications. Circuit boards should not be serviced in the field unless directed otherwise by Customer Service.

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

Troubleshooting

Electronic Circuit Breaker

The electronic circuit breaker works during a fault condition or an overcurrent which stops the module.

Remove the module and replace it in the frame. If the problem persists, please refer to 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 representative for depot location.

SNMP Features

Overview

In addition to the standard 8900 module SNMP monitoring reporting, the 8972PX module allows two read/write parameters to manage the input selection (Input Select) and module mode of operation (Switchback Strategy) through the SNMP interface. Refer to

Commands on page 80 for details.

The 8972PX module must be in a GeckoFlex frame with an 8900NET module running software version 4.2.0 or later, and the MIB (Management Information Base) version 2.0.0 must be used.

Appendix

Using Additional SNMP

The SNMP interface and its settings for the 8900NET module are described in the 8900NET Instruction Manual available online at this URL:

www.grassvalley.com/docs/modular

The version 2.0.0 MIB is available from the Grass Valley ftp site at this location:

ftp://ftp.grassvalley.com/modular/MIB/v2.0.0

8972PX — Instruction Manual 79

Appendix — SNMP Features

Using Additional SNMP Commands

To select the program input, use this parameter

(mcmFssInputSelect, OID 1.3.6.1.4.1.4947.2.3.2.1.2.4.1.8.slot#)

• input-primary (1)

• input-secondary (2)

• input-alternate (3)

To select the mode of operation, use this parameter:

(mcmFssSwitchbackStrategy, OID 1.3.6.1.4.1.4947.2.3.2.1.2.4.1.73.slot#)

• maintain-stability (1)

• maintain-primary (2)

•manual (3)

Note the following about using these commands:

• Setting the Program Input via SNMP (set mcmFssInputSelect) is equivalent to forcing the input with NetConfig.

• Reading the Program Input via SNMP (get mcmFssInputSelect) is just receiving information about the current input.

• Setting the Switch Mode via SNMP (set mcmFssSwitchBack-Strategy) is equivalent to forcing the Switch Mode with NetConfig.

• Reading the Switch Mode via SNMP (get mcmFssSwitchBack-Strategy) is just receiving information about the current Switch Mode.

Note These two parameters behave the same with SNMP as for NetConfig or using

the Newton Control Panel. In particular, if a specific input is forced, the module mode of operation becomes Manual.

For help in locating these MIB commands, the Input Select command is highlighted in the tree in is highlighted the tree in Figure 34 on page 82.
