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 62 ).
Refer to Figure 12 on page 20 for the location of PWR LED and Table 2 on
page 21 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.
