Interfaces Detailed Description

Power-On LED

There is one I/O LED (green) on the front panel, to indicate if the system is powered.

USB 3.0 Interfaces 

Skyway-3 offers 2x USB 3.0 ports on the system's rear panel. 

The USB interfaces are USB 3.0 compliant and can be used to provide the bandwidth up to 500MB/s to shorten the time for data transmission.

Do not use excessive force when inserting or extracting the USB disk to and from the connector.

PCIe Gen 5 Slots 

Skyway-3 is shipped assembled with eight ConnectX-8 VPI cards that enable the hardware-based forwarding of IP packets from InfiniBand to Ethernet, and vice versa. 

LAN Interfaces 

Skyway-3 features two GbE LAN 1/2 (Intel i350 (2* 10/100/1000 Base-T GbE)) to eliminate bottlenecks in network data flow. The ports are accessible from the appliance's rear panel.

In addition, the appliance is equipped with ASPEED 2600 BMC chip that supports IPMI 2.0 (Intelligent Platform Management Interface 2.0) via RJ-45 port.

The recommended cabling when connecting LAN1 and LAN2 (for 10G LAN) is Cat. 6 (< 55m) or Cat. 6A (<100m) for which both cross and straight cables are supported. 

Redundant Power Module

NVIDIA Skyway-3 is equipped with 3 redundant power supply units at the rear of the appliance. The PSUs are housed in a 2U canister containing the power supplies. Each PSU has an extraction handle, PSU status LED, and a power socket.

  • 80 PLUS Platinum 2+1 redundant power supply

  • 1000 W @ 100 ~ 127 V

  • 2000 W @ 200 ~ 240 V


  • For the redundant power module LEDs definitions, please refer to Power Module LED specifications

Fans Modules 

Power Supply Fans

NVIDIA Skyway-3 is equipped with one fan per power supply unit on the rear panel of the appliance.

Internal Fans 

NVIDIA Skyway-3 is equipped with six internal fans for cooling the CPU and expansion cards. Under normal operation, the cooling fans operate at a constant speed. If the system module fails, or one of the temperature thresholds are exceeded, the cooling fans automatically raise their rotation speeds to draw more airflow. For example, if there are two fans for CPU cooling and the temperature of CPU0 raises, only these two system fans will raise their fan speed and the other four fans for the cooling of expansion cards will operate at a constant speed. Below is a list of the different internal fan types. 


  • 6x 8cm heavy duty fans with optimal fan speed control

  • All fans are equipped with tachometer status monitoring
