The MikroTik CRS328-4C-20S-4S+RM is a fiber-first Cloud Router Switch designed for aggregation and distribution layers in ISP, enterprise, and lab networks. With high SFP port density and 10G SFP+ uplinks, it provides a scalable solution for consolidating fiber connections while maintaining flexible management through RouterOS or SwOS.

Where the CRS328-4C-20S-4S+RM is commonly used

  • Fiber aggregation in ISP and enterprise networks
  • Distribution switching between access and core layers
  • High-density SFP environments transitioning to 10G uplinks
  • Network labs and test environments requiring flexible port selection

The switch features twenty SFP ports for Gigabit fiber connections, four 10G SFP+ ports for high-speed uplinks, and four combo ports that support either SFP or RJ45 connections. Combo ports are software-selectable, allowing administrators to choose which interfaces are active based on deployment requirements.

Housed in a 1U rack-mountable enclosure, the CRS328 includes dual 100–240 V power supplies with failover support to ensure continuous operation. An RJ45 console port and configurable mode button provide additional management and troubleshooting options.

The CRS328 supports dual-boot operation, allowing administrators to choose between RouterOS or SwOS. SwOS offers a simplified interface focused on switching tasks, while RouterOS enables advanced routing, VLANs, and Layer 3 functionality when required.

Don't waste your money.
Instead of buying one from the local auto store, thought I'd save money and get this. Bad choice. Installed it and it didn't work. Took it to the auto shop to be tested and they said it didn't work. Cheap imitation of the the real thing.

Exceeds performance expectations of OEM fluids
Size: 5 Quart Jug
You know I didn't think it would work as well I've heard all these horror stories but you know what this works better than the factory CVT fluid this stuff is great this is amazing be very careful to get your levels correct that goes without saying with any transmission but once you do that this fluid is amazing I have a better performance than when I had the new transmission I serve my CvT 35 to 40,000 miles I'm using it in a 2018 Mitsubishi outlander base model and I'm also running Yokohama geolander 015s on it. If you worry about tires for you Mitsubishi or any vehicle. I'm going to say you'll call when you lander whether it's a car or crossover or an SUV this tire is amazing it's best all around tire and your rain traction is phenomenal

Good Stuff!! All low speed shudder is gone.
Size: 5 Quart Jug
I have a 2020 Nissan Altima SL 2.5l and Nissan is VERY specific about using ONLY NS3 transmission fluid. There are only a couple NS3 transmission fluid manufacturers...Nissan NS3 (Manufactured by Idemitsu), Idemitsu (a little cheaper than Nissan dealer), Triax, and Mannol (works good too). Seeing as Nissan is still using Jatco CVT transmissions which are known to be very troublesome, and very expensive to replace I wouldn't try any of the so-called "universal" transmission fluids just to save $50 and end up replacing a $6000 transmission. The Triax fluid seems to work very good in my car. I don't feel the shutter that I normally feel when driving slow and need to accelerate. The shudder is completely gone and operating smooth. The old fluid had 50k miles and it was very dirty but didn't smell burnt. I ended up doing 2 - 3 1/2 quart changes with 200 miles between the first and second change. I plan on doing another 3.5/4 quart change every 15k miles since there is no way to completely drain the 7.4 quarts of transmission fluid. The first change, only 3.5 quarts drained from the pan.
