Power Supply Installation Considerations
G‐Series switches can have up to two internal power supplies installed. Currently, two sizes of power supplies are offered. The following power supplies are available to be purchased from Enterasys for installation on the G‐Series switch:
•G3‐PWR, a 400‐watt AC power supply (requires a 15 amp circuit)
•G3‐PWR‐POE, a 1200‐watt AC power supply (requires a 20 amp circuit)
These power supplies perform load sharing and may be used in any combination. The following sections discuss the available power supply configurations.
Power Supply Redundancy
Two modes of power supply operation are supported:
•Redundant mode, in which the power made available to the system is equal to the maximum output of the lowest rated supply. When two supplies are installed in redundant mode, system power redundancy is guaranteed if one supply is lost.
•Non‐redundant, or additive, mode, in which the combined output of both supplies is made available to the system. In this mode, the loss of a single supply may result in a system reset.
The switch will support a full 15.4 watts of power to 96 ports in non‐redundant power mode, and
9.4watts of power to 96 ports in redundant power mode. By default, the G‐Series switch is set to operate in redundant mode when a second power supply is added.
