Power and Thermal Environmental Settings

Power mode

Governs the available power capacity and power management experience. Three redundancy configurations are supported:

Redundant power feed

The default N+N redundancy mode expects that half of the power supplies are connected to independent input power circuits. When set to Redundant power feed, the available power that can be allocated to enclosure components is equal to or slightly more than half of the total power supply capacity. The amount of power beyond half of the capacity is described as the power capacity boost in the enclosure (HPE Synergy frame) power section. In this redundancy mode, the enclosure can survive the loss of one of the two input power feeds, or the loss of half of the power supplies.

Redundant power supply

The N+1 redundancy mode. The amount of power that can be allocated to enclosure components is one power supply's capacity less than the total capacity. With this setting, the HPE Synergy frame can survive the loss of one power supply.

Basic power

When set to the Basic power mode, the amount of power that can be allocated to the enclosure components is equal to the total power supply capacity of all the installed and operational power supplies. Therefore, power capacity boost is not available and server throttling is disabled in this mode.

In this mode, when the power usage of the enclosure exceeds the capacity of all operational power supplies, the power supplies may go offline and servers may shut down unexpectedly.

Ambient temperature mode

Governs the ambient temperature for the enclosure to operate at higher temperatures.

Standard (35C / 95F)

Optimizes the Synergy frame to operate in environments with ambient temperatures up to 35 degrees Celsius.

ASHRAE 3A (40C / 104F)

Optimizes the Synergy Frame to operate in environments with ambient temperatures up to 40 degrees Celsius.

ASHRAE 4A (45C / 113F)

Optimizes the Synergy Frame to operate in environments with ambient temperatures up to 45 degrees Celsius.

Telco

Optimizes the Synergy Frame to operate in environments with standard ambient temperatures up to 40 degrees Celsius and operation extremes up to 55 degrees Celsius.
