Problem Solution
The operator can only
access one port on a
cascaded KVM switch
and cannot switch to
any of the other ports.
There is only one display channel for all the ports on a
cascaded KVM switch. The previous operator's access
timeout expired (see SET ACCESS TIMEOUT, page 44), so
the port is released, but his logout timeout has not expired so
the display channel has not been released.
To avoid this problem, be sure to set a reasonable logout
timeout (see SET LOGOUT TIMEOUT, page 42) for all
users.
When I emulate the Sun
keyboard, I can’t go into
OK Mode ([Stop] [A]).
To go into OK Mode, use the following key sequence:
1. Press and release [Ctrl].
2. Press and hold [T].
3. Press and hold [A].
4. Release [T] and [A] together.
Some computers on my
installation don’t seem
to receive Broadcast
Mode commands.
Broadcast Mode commands are sent from the console to all
computers, whether directly connected to the first stage
Matrix KVM Switch or attached to a daisy-chained Matrix
KVM Switch. (Broadcast Mode commands are not sent to
computers attached to cascaded KVM switches.)
Additionally, Broadcast Mode commands for one operating
system may not be recognized by another operating system.
