Power System
The single or dual power supply configuration is determined at boot up. If at boot up, only
one power supply is detected, then the single power supply configuration is set. If two
power supplies are detected, then the dual power supply configuration is set.
Standard AC Hot Swappable Power Supplies
The AC power system is designed to support two 350-watt hot-pluggable power supplies,
each with independent AC power cords and cooling fans. The base system has one power
supply with an option for a second power supply. This power system provides the enclosure
with “N+1” redundant power when both power supplies are installed. Each power supply
has auto-switching circuitry for use with either 100V or 240V AC systems.
AC Power Supply
Power is applied to the enclosure by pressing the power supply On/Off switch to the “On”
position. A Power On LED located on each power supply will be illuminated indicating
that AC power has been applied. The front bezels’ “Power On” LED will also be
illuminated indicating that power has been applied.
If the power supply cooling fan fails, the Fault LED will illuminate and the alarm will sound.
The power supply also has an amber general Fault LED. If you have a dual power supply
configuration and power is not applied to one of the power supplies, the general Fault LED
is illuminated.
