If you are upgrading the matrix switcher from a configuration with two power

supplies to a configuration with four power supplies (adding redundancy), you
also need to plug in the redundant IEC power cord on the rear panel.

.

If power supplies were installed to add redundancy to the switcher, plug a

standard IEC power cord between the rear panel Redundant AC Power Input

connector and either an uninterruptible 100 to 240VAC, 50 Hz or 60 Hz power

source or a power source that is completely independent from the primary

power source.
