Prevention
There are no user-serviceable parts in the compact routers, control panels, or remote panel
modules. No CR Series product requires any physical maintenance. However, we recommend
that you keep your devices free of dust, water, and contaminants, and ensure that cables are
organized so that they do not short, kink, or break.
Check periodically that your power supplies are working, especially if you are using the second
power connections for redundancy.
Occasionally, Grass Valley releases new versions of Compact Router software and firmware. If
you order a new router and your existing routers have older software and firmware, the new and
the old products might be incompatible. If you experience difficulties with new routers, contact
Grass Valley to request software and firmware upgrades.
Update all your network (CR Series) devices to the same firmware revision.
If a router fails, you can perform certain simple diagnostics. Call Grass Valley if the problem
cannot be solved easily.
Trouble-Shooting
If a CR Series device (router, control panel, or remote panel module) malfunctions, first examine
all input and output connections, all network connections, and all power connections. Verify
that cables are secure at both ends and that they are not broken. Determine that video sources
and destinations are on and functioning properly. Verify that the video reference is functioning.
If everything else in your system is functioning properly, the problem is at the device. Here are
some problems that can occur:
•
The LED corresponding to your power supply connection does not illuminate.
•
Noisy transitions.
•
The router gets power, but does not work properly or fails to “remember” its settings.
