❓ Frequently Asked Questions
🔌 Will this card work in a PCIe x4 slot?
Yes! The PI50R21 is designed for PCIe x4 slots and is also compatible with x8 and x16 slots. It will work at full 10Gbps speed in any of these configurations.
💻 Is this compatible with my NAS (Synology/QNAP/TrueNAS)?
Absolutely! This card works with most NAS systems including Synology, QNAP, TrueNAS, and Unraid. Make sure your NAS has an available PCIe slot and supports the Intel X550 chipset (most modern systems do).
🌐 Do I need a 10G switch to use this card?
Not necessarily! The card supports multi-speed operation (100M/1G/2.5G/5G/10G), so it will work with standard 1G switches at 1Gbps speed. For full 10Gbps performance, you'll need a 10G switch or direct connection to another 10G device.
🔧 Do I need to install drivers?
Yes, please download the driver package from the download section below.
⚡ What cables do I need?
For 10Gbps: Use Cat6a or Cat7 Ethernet cables (up to 100m). Cat6 cables work for shorter distances (up to 55m). For 1Gbps and below: Standard Cat5e or Cat6 cables are fine.
🖥️ Can I use both ports simultaneously?
Yes! Both ports can be used at the same time. You can configure them for link aggregation (bonding/teaming) for 20Gbps total bandwidth, or use them as separate independent 10G connections.
🌡️ Does this card require active cooling?
The card has a passive heatsink and typically doesn't require additional cooling in well-ventilated systems. Maximum power consumption is only 13W. Ensure your case has adequate airflow.
🔄 Can I use this for virtualization (VMware/Proxmox)?
Absolutely! The Intel X550 chipset supports SR-IOV with up to 64 virtual functions per port, making it perfect for VMware ESXi, Proxmox, and other virtualization platforms. It also supports VMDq and other advanced virtualization features.
📏 Will this fit in my small form factor (SFF) PC?
Yes! The package includes a low-profile bracket, making it compatible with both full-height and low-profile cases. Card dimensions are 130mm × 64mm.
