Rack mounting — Rack mountable in any conventional 19" wide rack.
Three front panel security lockout modes (Executive modes) — If a matrix
switcher is installed in an open area, where operation by unauthorized
personnel may be a problem, either of two security lockout modes can be
implemented (the third mode is unlocked). When a front panel locked mode
is enabled, a special button combination or SIS command is required to
unlock the front panel controller and make the front panel fully operational.
I/O grouping — Allows the matrix to be virtually divided into smaller
sub-switchers, making installation and control easier. I/O grouping
limits the selection of inputs and outputs to members of the same group.
I/O grouping allows specific outputs, such as those designated for a specific
purpose, to be grouped together.
Power — The matrix switchers' 100 VAC to 240 VAC, internal power supply(s)
provides worldwide power compatibility.
Primary and redundant power supplies —
(Matrix sizes 2412 and larger only) Includes two internal 100 VAC to 240
VAC, 50/60 Hz, switching power supplies, which provide worldwide power
compatibility.
The power supply circuitry is configured to automatically switch over from
the primary supply to the hot redundant supply in the case of a failure.
The hot redundant power supply means high reliability for the system and
no loss of functionality should the primary supply fail; the redundant power
supply immediately assumes the load.
Power supply status LEDs —
(Matrix sizes 2412 and larger only) Front panel LEDs indicate the status of
the primary and redundant power supplies.
