For more information, see NVIDIA T4.

Power supply unit specifications

The Azure Stack Edge Pro R device has two 100-240 V Power supply units (PSUs) with high-performance fans. The two PSUs provide a redundant power configuration. If a PSU fails, the device continues to operate normally on the other PSU until the failed module is replaced. The following table lists the technical specifications of the PSUs.

Specification 550 W PSU
Maximum output power 550 W
Heat dissipation (maximum) 2891 BTU/hr
Frequency 50/60 Hz
Voltage range selection Auto ranging: 115-230 V AC
Hot pluggable Yes

Battery specifications for UPS

The Azure Stack Edge Pro R device has the following specifications for UPS:

Specification Value
Battery type Lithium iron phosphate (LFP)
Battery voltage 48 Vdc
Battery capacity 5.0 Ah

Network specifications

The Azure Stack Edge Pro R device has four network interfaces, PORT1 - PORT4.

Specification Description
Network interfaces 2 x 1 GbE RJ45
PORT 1 is used as the management interface for initial setup and is static by default. After the initial setup is complete, you can use the interface for data with any IP address. However, on reset, the interface reverts to static IP.
The other interface, PORT 2, which is user-configurable, can be used for data transfer, and is DHCP by default.
Network interfaces 2 x 25 GbE SFP28
These data interfaces on PORT 3 and PORT 4 can be configured as DHCP (default) or static.

Your Azure Stack Edge Pro R device has the following network hardware:

  • Mellanox dual port 25G ConnectX-4 channel network adapter - PORT 3 and PORT 4.
