Functional Description
Functional Description
Input and Output Processing
The input section(s) receive SD (standard definition) video from the rear
input BNCs and send it to signal equalizing and reclocking circuits. The
input section can also bypass reclocking circuits to the output amplifiers.
The output amplifiers drive eight equal-phase outputs on the rear backplane for the 8937 and one set of four outputs and one set of three outputs
for the 8937D.
Note All outputs are in phase with the input signal.
Microprocessor and Input Selector
The primary purpose of the microprocessor is to provide remote control
and monitoring capability for the module. It receives signal present, signal
lock, and speed detection signals from the equalizer and reclocker circuits.
Using this information, local jumper settings, and remote control commands, the microprocessor selects the internal signal path and gives feedback through the LEDs and remote control bus.
User-enabled video presence detection generates individual SNMP traps
for each channel that can be sent to an SNMP manager via the microprocessor.

Service
Service
The 8937 and 8937D modules make extensive use of surface-mount technology and programmed parts to achieve compact size and adherence to
demanding technical specifications. Circuit modules should not be serviced in the field unless directed otherwise by Customer Service.
If your module is not operating correctly, proceed as follows:
•Check frame and module power and signal present LEDs.
•Verify power at the voltage testpoints (see Figure 18) and check fuse if
no voltage is detected.
•Check for presence and quality of input signals.
•Verify that source equipment is operating correctly.
•Check cable connections.
Refer to Figure 7 for the location of PWR LED and Table 2 on page 14 for
proper LED indications.
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.
Refer to the Contacting Grass Valley at the front of this document for the
Grass Valley Customer Service Information number.

Status Monitoring
Status Monitoring
This section provides a summary of status monitoring and reporting for a
Gecko 8900 Series system. It also summarizes what status items are
reported and how to enable/disable reporting of each item. There are a
number of ways to monitor status of modules, power supplies, fans and
other status items depending on the method of monitoring being used.
8900 Frame status will report the following items:
• Power supply health,
• Status of fans in the frame front cover,
•Temperature,
•Module health, and
• Frame bus status.
Module health status will report the following items:
• Internal module state (and state of submodule or options enabled)
including configuration errors (warning), internal faults, and normal
operation (Pass).
LEDs
• Signal input states including valid/present (pass), not present or
invalid (warning), not monitored (unknown), and not available (no
signal inputs).
•Reference input states including locked/valid (pass), not
locked/invalid (warning), and not monitored (unknown).
• Signal output states with reporting functionality (reference output).
LEDs on modules in the frame and on the front of the 8900TF/TFN frames
indicate status of the frame and the installed power supplies, fans in the
front covers, and modules.
When a red FAULT LED is lit on a frame front cover, the fault will also be
reported on the 8900NET or Frame Monitor module. The LEDs on the front
of these modules can then be read to determine the following fault conditions:
• Power Supply 1 and 2 health,
• Fan rotation status,
• Frame over-temperature condition,
• Frame Bus fault (8900NET only), and
•Module health bus.
32 8937/8937D Instruction Manual
Page 33
Frame Alarm
Status Monitoring
In general, LED colors used on the frame and modules indicate:
•Green = normal operation, (Pass) or signal present, module locked.
•Red – On continuously = fault condition, flashing = configuration error.
•Yellow – On continuously = active condition (configuration mode or
communication), flashing in sequence = module locator function.
Status LEDs for this module are described in Operation Indicator LEDs on
page 14. LEDs for the 8900NET module are described in the 8900NET
Network Interface Instruction Manual.
A Frame Alarm connection is available on pins 8 and 9 of the RS-232 connector on the rear of the 8900 frame (Frame Monitor or 8900NET Network
Interface module required). This will report any of the status items enabled
with the 8900NET or Frame Monitor module configuration DIP switch.
Connection and use of the Frame Alarm is covered in detail in the 8900NET
Network Interface Instruction Manual.
Web Browser Interface
When the 8900NET module is installed in the frame, a web browser GUI
can indicate frame and module status on the following web pages:
• Frame Status page – reports overall frame and module status in graph-
ical and text formats.
•Module Status page – shows specific input and reference signal status
to the module along with enabled options and module versions.
•A Status LED icon on each web page to report communication status
for the frame slot and acts as a link to the Status page where warnings
and faults are displayed (8900NET version 3.0 or later).
In general, graphics and text colors used indicate the following:
•Green = Pass – signal or reference present, no problems detected.
•Red = Fault – fault condition.
•Yellow = Warning – signal is absent, has errors, or is mis-configured.
•Gray = Not monitored (older 8900 module).
•White = Not present.
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.
8937/8937D Instruction Manual 33

Status Monitoring
SNMP Reporting
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.
There are both hardware and software report enable switches for each
report. Both must be enabled for the report to be sent. Software report
switches are set on the 8900NET Configuration page for the Frame, the
8900NET module, and each module slot. Refer to the 8900NET Network
Interface Instruction Manual for installation instructions.
