Power Supplies
The Nokia 500s appliance supports up to two power supplies for power
sharing and redundancy. The 500s comes with two power supplies as the
standard package. The power supplies are hot swappable and perform load
sharing while two active power supplies are installed, increasing the life of the
power supplies.
Note
On an appliance with two active power supplies installed, both power
supplies should be turned on for load sharing and redundancy. If both
power supplies are not turned on, the Fault LED illuminates. For more
information about the power supply status LEDs, see
"Power Supply
Status LEDs"
on page 30.
The power supplies are autosensing and can accept input voltages between
85 VAC and 264 VAC. The power supply output is regulated to a tolerance of
± 5 percent of the specified output voltage.
