Introduction
This chapter provides information about operating your PS9648 Power Supply after it is installed.
Power Switch
The PS9648 has a power switch on the front panel that is labeled with the international I (on) and O (off)
symbols. For the most reliable operation, both power supplies should be turned on whenever the
CommPlete Communications Server is operating.
Power Indicator
The power indicator lights if all outputs are good. If any one of the outputs on the power supply goes bad,
this indicator goes out. If a power supply fails and the redundant power supply is installed and turned on,
the good power supply takes over with no switchover time.
