Power Supplies
The Nokia IP2255 appliance supports two power supplies for enhanced power
sharing and redundancy. The power supplies are hot swappable and perform
load sharing while two active power supplies are connected in parallel. Load
sharing increases the life of the power supplies.
Note
Both power supplies should be turned on for load sharing and
redundancy.
The power supplies are autosensing and can accept input voltages between
100 to 127 VAC and 200 to 240 VAC. The power supply output is regulated to
a tolerance of ± 5 percent of the specified output voltage.
For information about how to replace a failed power supply, see “Replacing a
Power Supply” on page 98.
Power Supply Status LEDs
Three status LEDs are located on each power supply, as shown in Figure 8 .
