We have not found the unit to be picky with optics and DACs, unlike our Ubiquiti EdgeSwitch ES-16-XG. Looking at the front, the primary feature here is an array of 16x SFP+ 10GbE ports. It is also designed to mount on 2-posts rather than 4-posts like many larger switches. One can use rubber feet to mount the unit on a desk even though it is large for a desk unit. Officially the size of the unit is 443 x 224 x 44 mm (17.4 x 8.8 x 1.73 in) which means it fits well into a 1U rack space. This denotes that it is a rackmount chassis, even though the CRS309 came with a rack mounting solution. The Mikrotik CRS317-1G-16S+RM has an “RM” instead of the “IM” suffix that we saw on the CRS309. That makes these switches a great value for what they offer compared to others on the market. Perhaps the best part is that although the MSRP is $399 for this we can often find them online for under $350 or $21-22 per port. This is a 16-port SFP+ 10GbE switch with redundant power supplies and even a 1GbE port for out-of-band management like many higher-end switches. That is exactly where the MikroTik CRS317-1G-16S+RM comes in. When we reviewed the 8-port MikroTik CRS309-1G-8S+IN, we noted a few features that we wanted such as internal power supplies, and oftentimes more ports. MikroTik CRS317 1G 16S+RM Internal Heatpipes
