The system-error LED might light, and a KVM allocation error might be logged, if the change in ownership for the CD-ROM drive, diskette drive, and USB port, or the keyboard, video, and mouse takes more than 8 seconds. The system-error LED will go off after the ownership change is complete. 2. It can take up to 48 seconds after a blade server is initially turned on before you can attempt to switch KVM control to that blade server.
