Overview
Each FR6822

frame is equipped with one self-contained 6822
+
AC power supply unit that
can support an entire frame load. An optional redundant PSU can be ordered separately. If
the frame has two PSUs installed, the load is shared equally during normal operation. Each

AC power supply includes a temperature monitoring sensor. The sensor is installed at
the output of each power supply’s air flow, and generates alarms when the readout
temperature reaches predefined levels.
