Technical FAQ

Is the VF701 S2 compatible with legacy Vnet or VLnet systems?
No. The VF701 S2 is designed exclusively for Vnet/IP. Legacy Vnet or VLnet systems require different interface cards.

Does the VF701 S2 support redundancy?
Yes. The card includes two independent Ethernet ports to support Vnet/IP redundancy and uninterrupted network operation.

What is the difference between Style 1 and Style 2 (S2)?
The S2 version incorporates updated electronic components for improved thermal performance and service life, while maintaining full functional compatibility with earlier versions.
