The 8900NET 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 ser-
viced in the field.
If your module is not operating correctly, proceed as follows:
•
Check frame and module power and signal present LEDs.
•
Check network connections at the frame and network routing devices.
•
Verify that all ethernet devices have a unique MAC and IP Address/
Domain Name.
•
Reboot the 8900NET module (see

spare and return the faulty module to a designated Grass Valley repair
depot. Call your Grass Valley representative for depot location.
