IP-VFC FAQs
I. SFPs
Section titled “I. SFPs”How reliable are the SFPs that have been tested with IP-VFC?
Section titled “How reliable are the SFPs that have been tested with IP-VFC?”As part of our QA processes, the SFPs outlined in the list of supported SFPs have been used alongside the IP-VFC in the same testing environments, often over several days at a time with no issue. Long range SFPs draw more power and so run hotter during operation. That is expected, and they are tested and supported like the rest of the list.
II. ST 2110 and Fabric
Section titled “II. ST 2110 and Fabric”What’s the behaviour of Port 2 on the IP-VFC when running redundancy in ST 2110 mode, and will it impact the GPU load on the server by running a redundant video stream?
Section titled “What’s the behaviour of Port 2 on the IP-VFC when running redundancy in ST 2110 mode, and will it impact the GPU load on the server by running a redundant video stream?”There is no difference in GPU load. The redundant video stream is completed internally to the IP-VFC.
When using ST 2110 mode in multicast, can you use the boundary clock on the Fabric for timing instead of a PTP grandmaster?
Section titled “When using ST 2110 mode in multicast, can you use the boundary clock on the Fabric for timing instead of a PTP grandmaster?”Fabric by default will act as a boundary clock so that will most often be the case.
Can you use a Fabric in the same configuration for RenderStream on one port/VLAN and ST 2110 on another?
Section titled “Can you use a Fabric in the same configuration for RenderStream on one port/VLAN and ST 2110 on another?”Yes. Fabric uses one configuration for both, so you do not need to load a different configuration to run RenderStream and ST 2110 alongside each other.
III. SDI
Section titled “III. SDI”Why can’t the IP-VFC support 2160p60 at RGB 4:4:4 10-bit in SDI mode?
Section titled “Why can’t the IP-VFC support 2160p60 at RGB 4:4:4 10-bit in SDI mode?”The IP-VFC is limited in SDI mode by 12G SDI, which means that it has a bandwidth of 12 Gbit/s. We offer YUV 4:2:2 support up to 4K DCI 60p in 10-bit which reaches around 11.2 Gbit/s. We are therefore restricted by bandwidth constraints and would have to consider lower framerates (i.e. 24p) on a case-by-case basis.
IV. Updater
Section titled “IV. Updater”How can I update the firmware of the IP-VFC?
Section titled “How can I update the firmware of the IP-VFC?”We have put together documentation on how to update the firmware of the IP-VFC available here.
