Power Supplies
The Nokia IP1200 Series appliance supports up to two power supplies for power sharing and
redundancy. The IP1260 comes with two power supplies as the standard package. The IP1220
comes with power supply; a second one is optional. 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 28.
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.
Caution
The Nokia IP1200 Series appliance power supply might be hot to the touch when the
power supply unit is plugged in to an AC power source
and the power supply is not
turned on. This is because the internal cooling fan for each power supply runs only
when the unit is turned on.
