HPTFT5600 RKM Problem

[Yurij Salmaniw]

Have DL380G4 with Rack Keyboard Monitor, however on cold boot, the screen goes white. If I depress the display switch, the screen resets and the POST information is displayed properly. Any ideas as to why this may be happening?

Yra, all server does do that or only DL380G4 ?

I have seen advisory about this issue, but now link goes to error page (may be removed?). As from advisory this behavior is by design.

1. Power up the KVM and allow sufficient time for initialization.
2. Power up the TFT5600.
3. Power up the server.
