Service
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 Rebooting the NET Module on page 36).
Refer to Figure 10 on page 16 for the location of PWR LED and Table 1 on
page 17 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 Contacting Grass Valley at the front of this document for the Grass
Valley Customer Service Information number.
