Mac users.
NOTE:
The DSR switch on-board web interface uses system memory to store and display images within Video
Viewer windows. Each opened Video Viewer window requires additional system memory:
• An 8-bit color setting on the client PC requires 1.4 MB of memory per Video Viewer window.
• A 16-bit color setting requires 2.4 MB and a 32-bit color setting requires 6.8 MB.
Opening more than four simultaneous Video Viewer windows may affect system performance and is not
recommended. If you attempt to open more Video Viewer windows than your system memory allows, you will
receive an out-of-memory error and the requested Video Viewer window will not open.
If the device you are attempting to access is currently being viewed by another user, you will be
prompted to preempt the other users if your preemption level is equal to or greater than theirs. An
appliance administrator can also disconnect an active user via the Active Session page. For more
information, see To disconnect an active KVM session (administrator only): on page 47.
