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.
