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. 
Service
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.
Power-up Diagnostics Failure
If the module has not passed self-diagnostics, do not attempt to trouble-
shoot. Return the unit to Grass Valley (see 
below).
Troubleshooting
Electronic Circuit Breaker
The electronic circuit breaker works during a fault condition or an overcur-
rent 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.
Contacting Grass Valley
