Trouble-Shooting
Power Supply LED Does Not Illuminate
If the device is otherwise functioning properly, the problem is a faulty LED. (Call Grass Valley for
service.) If the router is not functioning at all, take the following steps.
Determine whether the external power supply delivers power. (If you cannot do this, call Grass
Valley.) If it does deliver power, try using the other PS connector. If neither connector works, the
router is “dead.” If one PS connector works and the other doesn’t, the router is defective.
The Grass Valley power supplies (part number PS0012-00) have an indicator lamp. If the indi-
cator lamp is off, either the power supply is dead or the AC socket is defective or not connected.
Try plugging the power supply into another socket that you know is working. If the power
supply’s indicator light remains off, the power supply is dead. Otherwise, the AC socket was the
problem.
Noisy Transitions
Try using a video reference to align video (and audio) transitions with the sync in the video
reference.
Verify that the video reference signal is appropriate for the router, well-formed, and terminated.

If you use one of the composite analog signals (525 or 625) as a reference, you will probably
introduce switching transients. Because SMPTE specifies the switch point for HD as NTSC line
4, using a composite reference might cause the switch point to occur at the wrong place in
the HD stream. You might see switching transients. (The composite switch point is specified
as NTSC line 10.) Embedded audio will have a noticeable discontinuity.
Router Functioning Improperly
If the router gets power, but the router does not transmit signals properly or does not switch
properly, the router has an indeterminate problem. Call Grass Valley.

Level selection can be confusing: when all levels are selected, level buttons are not toggles.
Pressing a level button in this situation
turns off all other levels and leaves the one you
selected on. This is by design. Please do not think this is a malfunction.
If a router malfunctions, try resetting the router. Set its rotary switch to 0 and cycle power. Doing
that restores the router to its factory default state.
A control panel powers up in ‘Panel Lock’ state. The ‘Panel Lock’ button at the top right is bright
red. Be sure to press ‘Panel Lock’ once (it turns low-tally green) so that the panel can operate.
Network Failure
Determine whether the Ethernet switch has power. If it has power, check whether the switch is
broken. A quick check is to see whether the switch’s activity lights are on or active.
Check the amber and green lights on the Ethernet port on your router or remote panel module.
These should be on and steady (not blinking).
Check your cables. They might be defective or of the wrong type. If your devices are very far
apart, the cable might be too long.
Again, check power.
