- PRM 1 (houses full-height PCIe cards) and PRM 2 (houses half-height PCIe cards) support different types of PCIe cards. The figure is for reference only.
- FlexIO cards support two 100GE NICs. This figure is for reference only.
OCP NIC 3.0 cards and FlexIO cards are not hot-swappable. Power off the server before replacing them.

Description |
|---|---|---|---|
VGA port |
DB15 |
1 |
The VGA port is connected to a terminal, such as a monitor or physical KVM. NOTE:
If the VGA ports on both the front and rear panels are connected, the VGA port on the front panel is used preferentially. |
USB port |
USB 3.0 |
2 |
The USB ports allow USB devices to be connected to the server. NOTE:
Before connecting an external USB device, check that the USB device functions properly. The length of the USB extension cable cannot exceed 1 m. A server may operate abnormally if an abnormal USB device is connected. |
Management network port |
RJ45 |
1 |
This 1000 Mbps Ethernet port is used for server management, and supports 10/100/1000 Mbps auto-negotiation. |
Serial port |
RJ45 |
1 |
The serial port is used as the system serial port by default. You can set it as the iBMC serial port by using the iBMC command. This port is used for debugging. |
Optical port |
SFP |
2 |
LOM ports provide two GE optical ports. |
FlexIO card port |
100GE optical port (QSFP28) |
2/8 |
Each FlexIO card provides two 100GE optical ports, and four FlexIO cards provide a maximum of eight 100GE optical ports. NOTE:
|
PSU socket |

4 |
Determine the number of PSUs based on actual requirements, but ensure that the rated power of the PSUs is greater than that of the server. You are advised to configure four PSUs to ensure reliable device operating. When two PSU is used, System > Power > Power Supply Info > Power Supply Settings cannot be set to Active/Standby on the iBMC WebUI. |
