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.
