and eHBA Tri-Mode Storage Adapters
used. For adapters with auxiliary power connectors, the slot power check is bypassed if the auxiliary power connector is
connected. For more information on the auxiliary power connector, see Auxiliary Power Connector.
MegaRAID Tri-Mode Storage Adapter Power Supply Requirements
The following table describes the typical power consumption of the MegaRAID adapters.
Table 40: MegaRAID Tri-Mode Storage Adapter Typical Power Consumption
Adapter Typical Power (W)
9670W-16i 28
9670-24i 28
9660-16i 20
During the transparent learn cycle, the CacheVault power module consumes up to an additional 8W. The PCIe 3.3V rail
supplies the power for the learn cycle.
eHBA Tri-Mode Storage Adapter Power Supply Requirements
The following table describes the typical power consumption of the eHBAs.

Overtemperature Behavior
The adapter supports the following temperature threshold events to alert of overtemperature situations when sufficient
airflow is not provided. If supported, the system can use the events generated in the Persistent Event Log (PEL) to
manage fan speed and mitigate overtemperature conditions. While these events assist in managing overtemperature
conditions, potential damage can occur if sufficient airflow is not provided to the adapter.

Condition
RoC or IOC Junction
Temperature (°C)
Result
Warning 105 Generate a PEL event.
Critical 107 Generate a PEL event and decrease device-side ports to their slowest operating speed.
The junction temperature must return to 104°C, or lower, to resume normal operation.
Fatal 115 Generate a PEL event and fault the adapter. The junction temperature must return to
104°C, or lower, and the adapter must be reset to resume normal operation.
