For more information, see NVIDIA T4.

Power supply unit specifications

The Azure Stack Edge Pro 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 750 W PSU
Maximum output power 750 W
Frequency 50/60 Hz
Voltage range selection Auto ranging: 100-240 V AC
Hot pluggable Yes

Network interface specifications

Your Azure Stack Edge Pro device has six network interfaces, PORT1- PORT6.

Specification Description
Network interfaces 2 X 1 GbE interfaces – 1 management interface Port 1 is used 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 back to static IP.
The other interface Port 2 is user configurable, can be used for data transfer, and is DHCP by default.
4 X 25-GbE interfaces – These data interfaces, Port 3 through Port 6, can be configured by user as DHCP (default) or static. They can also operate as 10-GbE interfaces.

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

  • Custom Microsoft Qlogic Cavium 25G NDC adapter - Port 1 through port 4.
  • Mellanox dual port 25G ConnectX-4 channel network adapter - Port 5 and port 6.

Here are the details for the Mellanox card:

Parameter Description
Model ConnectX®-4 Lx EN network interface card
Model Description 25 GbE dual-port SFP28; PCIe3.0 x8; ROHS R6
Device Part Number (R640) MCX4121A-ACAT
PSID (R640) MT_2420110034

Enclosure environment specifications

This section lists the specifications related to the enclosure environment such as temperature, humidity, and altitude.

Temperature and humidity

Enclosure Ambient temperature range Ambient relative humidity Maximum dew point
Operational 10°C - 35°C (50°F - 86°F) 10% - 80% non-condensing. 29°C (84°F)
Non-operational -40°C to 65°C (-40°F - 149°F) 5% - 95% non-condensing. 33°C (91°F)

Airflow, altitude, shock, vibration, orientation, safety, and EMC

Enclosure Operational specifications
Airflow System airflow is front to rear. System must be operated with a low-pressure, rear-exhaust installation.
Ingress protection (IP) This type of rack-mounted equipment for indoor use typically isn't tested for ingress protection (protection against solids and liquids for an electrical enclosure). Manufacturer's safety assessment shows IPXO (no ingress protection).
Maximum altitude, operational 3048 meters (10,000 feet) with maximum operating temperature de-rated determined by Operating temperature de-rating specifications.
Maximum altitude, non-operational 12,000 meters (39,370 feet)
Shock, operational 6 G for 11 milliseconds in 6 orientations
Shock, non-operational 71 G for 2 milliseconds in 6 orientations
Vibration, operational 0.26 GRMS 5 Hz to 350 Hz random
Vibration, non-operational 1.88 GRMS 10 Hz to 500 Hz for 15 minutes (all six sides tested.)
