There is one I/O LED (green) on the front panel to indicate if the system is powered. For power-on LED definitions, please refer to section "Power-on LED".

UFM Cyber-AI Appliance offers 4x USB 3.0 ports on the system's rear panel. These interfaces can be used to provide up to 500MB/s in bandwidth.

Important

Do not use excessive force when inserting or extracting the USB disk into and from the port.

UFM Cyber-AI Appliance is shipped preassembled with two ConnectX-6 VPI cards that enable the hardware-based forwarding of IP packets from InfiniBand-to-Ethernet, and vice versa.

UFM Cyber-AI Appliance features two 10G Base-T Ethernet LAN 1/2 connections (Intel X557 PHY (2* 10GbE)) and two GbE LAN 3/4 (Intel I210 (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 a ASPEED 2500 BMC chip that supports IPMI 2.0 via LAN1 and LAN4 interfaces.

The recommended cabling when connecting LAN4 and LAN1 (for 10G LAN) is Cat. 6 (< 55m) or Cat. 6A (<100m), both cross and straight cables are supported.

LAN3 (X557-AT2 controller) has an internal signal connected to BMC LAN2.

UFM Cyber-AI Appliance is equipped with two 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 1+1 redundant power supply:

  • 1000W @ 100 ~127V

  • 2000W @ 200 ~240V

For the redundant power module LEDs definitions, please refer to Power Module LED Specifications.

Power Supply Fans

UFM Cyber-AI Appliance is equipped with one fan per power supply unit on the rear panel of the appliance.

Internal Fans

UFM Cyber-AI Appliance is equipped with six internal cooling fans for the CPU, GPU, and expansion cards. When the system is operating normally, the cooling fans operate at a constant speed. If the system module fails, or one of the temperature thresholds have been exceeded, the cooling fans automatically raise their rotation speeds to draw more airflow.

All fans are equipped with tachometer status monitoring.
