Windows – “No Signal” when attempting remote console redirection using a BMC with RMM4

bmcremote-accesswindows

I have recently purchased a high-end chassis system for use in my home office (I am a contract programmer).

The system includes a baseboard management controller (BMC), and in addition a remote management module (RMM) version 4.

The BMC allows for remote management of the power state of the machine (and other features) that is mostly independent of the state of the operating system, via the LAN port that is shared by the operating system. The RMM4 provides an independent LAN connection that accesses the BMC. There is a web management console that provides access to the features of the BMC, simply by typing the URL of the RMM4.

I am able to access the web management console just fine:

BMC Web Management Console

Furthermore, when I go to the tab to initiate a remote control screen redirection, the feature is enabled:

BMC Remote Control tab

Unfortunately, when I attempt to initiate a remote control session, the required Java application successfully runs, but "No Signal" appears in the window:

BMC "No Signal" during remote control session

Note that the machine is on and the monitor attached directly to the machine displays the expected Windows session.

Note: I think this issue MIGHT have something to do with the fact that video is being output to an NVidia card, not the on-board video chip (setting this system up required changing a BIOS setting).

Here are the stats:

  • dual Xeon E5-2687W
  • W2600CR2 board
  • Cosmos CoolerMaster chassis
  • 64 GB RAM

Any help would be appreciated.

Cannot be done. RMM4 supports redirection only of the native graphics chip, not an external graphics card. It is not possible to redirect external graphics card traffic to IPMI KVM because the IPMI chip may not know what is being rendered by the external card.
