Common Kumo Router errors & problems
What techs run into most, and what's usually behind it. The step-by-step fix for your exact unit is in Ask Roadie.
- Step-by-step fixGet the fix →
Fresh KUMO out of box / don't know its IP address to reach the web UI
Likely cause: eMini-Setup talks to the router over USB independent of the network, so it works even when you have no idea what subnet the unit landed on.
- Step-by-step fixGet the fix →
Ganged/dual-link routing for 4K/UltraHD across a 3G-SDI KUMO
Likely cause: Square-division/two-sample-interleave 4K is carried across multiple 3G-SDI links; ganging them makes the router treat the group as one signal so the quadrants stay together and in sync.

Keeping KUMO current / how to update firmware and what the latest version is
Likely cause: AJA delivers KUMO firmware as a web-uploaded package; running mismatched router/panel firmware is a common cause of a panel showing offline or misbehaving, so both should be on the same current release.

KUMO CP / CP2 control panel shows offline or won't drive the router
Likely cause: The panel finds and commands the router over IP; a wrong target IP, a subnet mismatch, or a router/panel firmware gap breaks that link and the panel reports offline even though both devices are powered.
- Step-by-step fixGet the fix →
KUMO not showing up on the network / web page unreachable after it was working
Likely cause: USB config bypasses the network entirely, and the Identify function isolates which physical unit you are on.
- Step-by-step fixGet the fix →
Maximize uptime / what happens if a power supply dies mid-show
Likely cause: The router accepts two independent DC feeds into one bus; if one supply or mains leg fails the other carries the full (low) load with no interruption.

Reference/genlock hookup for a KUMO in a synchronous plant
Likely cause: A looping 75-ohm reference bus must be terminated once at its end; feeding external black burst or tri-level sync lets the router time its crosspoint switches to house reference to avoid glitches on air.
