Power Supply Redundance
During normal operation, the Acme Packet 4600 is load-balanced and draws power
from both supplies. The two power supplies also provide hardware redundancy. If
a power supply fails, the Acme Packet 4600 can rely on only one functional power
supply to sustain normal operation. A malfunctioning power supply must be removed
and replaced as soon as possible. If the Acme Packet 4600 starts up with only one
power supply, it will not generate an alarm.
AC Power
The auto-sensing AC power supply is rated at 110-240 VAC, 50-60 Hz, and is supplied
with an IEC connector. The handle on the front panel of the power supply is used
to remove the power supply from the chassis. The gray locking handle, when moved
from right to left, unlocks the power supply from the chassis when removing the power
supply.
AC Power Cords
All AC-powered systems ship with two 2.5m power cords. Each power cord connects
to the IEC-320 C14 receptacle on the power supply.
