Upon speaking with the FS team, we have managed to resolve all issues very quickly. The team was very helpful and very quick to respond. This switch has quite a high rate of software update. That forces us to freeze the configuration. The team really took that hassle out of what initially appeared to be a complex procedure to keep the configuration locked while updating the software.

Repurchase of S5850-48S6Q. The AM told me the switch I got this time has now equipped with FSOS 7.2.2 software. I checked the previous one which is 7.2.1 version. Upgrade it with the help of the AM quickly.

I know FS from my customer who has purchased a lot of FS equipment and asked me to build out the new network. Though I am Cisco certified, I did not have any experience with FS kits. I called them for some help, and they replied kindly and sent me some documentation and configuration templates. The first time tinkered around their products leave me very good impression on the switch S5850-48S6Q. Use CLI to configure and web to modify later. MLAG supported ensures full redundancy. I have purchased a lot of the switch for different projects. No complains. I highly recommended FS.

We have deployed seven 24-port FS PoE+ switches (the first in 2017, the most recent this week). They have been extremely reliable and, once you get the web interface figured out, easy to configure. They powered our IP Phones and security cameras. Now we want some heavier switch boxes to run as the host core switches, already deployed huawei s6720-30C-EI-24S-AC works as the storage switch. You just name one thing, and FS AM prepares for you all the matched products. Compatibility is no longer the concern. Finally purchased 2pcs S5850-48S2Q4C, 2pcs S5850-48S6Q and 16pcs DAC cables of varied lengths. DAC saves a lot money compared with fiber patch cable plus transceiver modules.

N8000 switch I got last time didn't support Web Gui. Well, this one has both cli and web gui function for configuration and management.

I bought this switch as a replacement for our old cisco nexus 3172PQ. It meets all our needs since it provides salient functions as an aggregation switch. In my experience, it’s hard for us to find an equivalent to this switch at such a budget.

We need switches that can do many MLAGs and this switch can be configured with up to 55 active MLAGs simultaneously. The support from FS is strong and prompt when we need some guidance in connecting all devices.

I've been a fan of FS products for a few years now, most of our transceivers and DACs deployed in the environment came from them. I've been wanting to try out their switches and finally got this chance: we are starting as Internet Service Provider in France. Recently we plan to build a network supporting DATA to deliver FTTO and FTTE to our customers, and we need at least 2 core switches that should be able to provide BGP, OSPF, and BFD option. Besides, we need 4 devices for aggregation and 4 for access. All the access ports have to be 1Gb ports at minimum.
I researched switches for ages before settling with the S5850-48S6Q. We had considered the Brocade VDX 6740 but the cost was way too much for our budget, and we were informed that they are too picky regarding optics. After reading through the PDF manual for the S5850-48S6Q switch, I found that the port configuration and rich feature sets are rather similar with the VDX. Besides, the S5850 is cost-friendly and more accommodated to generic transceivers, this way I can use the optics right at hand. So I ordered two of them for testing.
My S5850-48S6Q arrived at my doorstep just on time. They are well-packaged with corrugated boxes to protect the items from any damage, vibration or mishandling in transit. The switches are made of solid metal and the build quality is top notch. The feature set is just right for me. It appears to do everything I’ve expected, like VLANs, Link Aggregation, MAC and 802.1x. I'm personally using most of the Qos features, several VLANs and lots of security features. They also support any of the features a core switch may need, including IPv6 static routing, link-aggregation groups (port-channel/bonding), and DHCP. Setting up VLAN, isolated networks, firewall was an absolute breeze, and configuring everything was somehow a pleasant experience as opposed to any network gear I've worked with in the past.
Management and configuration is smooth and painless through either the GUI or via the CLI. The web interface may be the most straightforward way to set up all the basic functions. But personally I prefer to use CLI to do most of the configurations. The CLI of this switch is rather identical to that of enterprise Cisco devices (I have used previously in my limited experience). So those familiar with IOS will find it’s easier to manage the switch.
The noise level is somewhere in the middle when you compare it to other equipment in the 1U form factor. But different people may not share the same opinion. It depends on the occupants of the office/setting where this switch will be installed. As for the power supply, the S5850-48S6Q is primarily with default AC power supply, and we asked to add DC power and they are capable to provide it. I love that the power supply is built inside the frame on this unit.
Overall, these switches are no-brainer at this price point, and I am very pleased with them. The sturdy design and performance meets my expectation as they just offer everything I want and also a lot to experiment/learn. The seller is an excellent company and serviced many of the businesses I worked for in the past. I would definitely recommend this product and consider to buy more.

As a cloud service provider, we were about to build a data center in Switzerland to better serve our customers. We planned to expand the network storage: needed each of our racks to have 8 nodes with dual 10G SFP+, an IPMI port, and a management port. So there will be about 6PB of HDD storage and 1PB of SSD storage. Most of that storage will be addressable from the Internet. We’ve consulted FS sales and tech staff several times on the layout of our network. Got fast response and solid supports all the time. At last we decided to go with the spine-leaf topology. This exactly fits our needs but also gave us enough space for future growth. Now we have 2 S8050-20Q4C switches as spine switches to get reliable backbone transmission. 20 S5850-48S6Q are running as leaf switches to handle the traffic from access devices and are uplinking to the 2 S8050-20Q4C. We also use their S3900-48T4S as access switches that deliver 1Gbps to the servers. MLAG was used to increase the redundancy at the spine and leaf layer. My order was shipped in a timely manner and the sales.rep helped me track the package in the process. My switches came well-packed with foam mats inside and without any damage or scraping.
Now, we have been using the switches for nearly six months without a reboot. My overall experience with their switches has been very positive and I really appreciate them putting the data center level equipment in our hands so affordably. Hopefully this would help you pick the unit that fits your needs rightly.

I have bought several times from this supplier. I am a purchaser of a big company and purchase many times from many suppliers. FS is one of the best suppliers I can find. They never let me down. In the other hand, I suggest improving the searching function of the website more convenient and useful so that I can find the switches I want to buy at a glance.
