Amazon sent me a Zyxel GS1900-16 instead of a GS1900-8HP, not once, but twice.On my third order of the 8HP, I received the correct unit. It is solid and well made. Very sturdy metal case. Unit itself is small but power brick is BIG. Too big. Oh well... You remove 2 phillips screws to get the case open. Electronics look high quality with no visible quality control issues.Instructions SUCK. No paper manual included, just quick start guide with basic cable connection diagrams to get you plugged in. Not much in the way of setup instructions other than the default IP of 192.168.1.1.Zyxel does have a pretty good .pdf documentation of all the settings and whatnot on their website. Their youtube videos are pretty good as well.But just connecting to the web GUI was hard to figure out because you don’t automatically get assigned an IP. This switch has no way of doing DHCP, so to get a local IP address, you need to change metwork settings to specify a local client IP address on same subnet as the switch’s default of IP (192.168.1.1), and you should be able to leave “default gateway” and “dns” fields blank while you configure client network settings to connect to the switch for the first time. Or connect the switch to a router or gateway that assigns IPs. If your router is default IP of 192.168.1.1, then either the router or switch will need different local IP as they can’t be the same, but they are by default.Once I figured out how to get properly connected to the web GUI, and once I trained myself to remember to “Save” the settings so that they carry over after a restart (or restart without saving if something screws up, reverting back to previous good config), the rest of the setup was easy. This is my first network switch, so really pretty easy considering I’m a networking noob. Firmware is more or less intuitive and seems to have all the right features, although I’ve never dug into the settings of a managed switch before. Make sure to update the firmware immediately as I think it ships with an old version which has been updated to fix security issues, so very important to install that new update!I’ve yet to hook up any PoE cameras, but I’m sure that will be no trouble. Speeds are FAST. I may be noticing a slight latency increase as could reasonably be expected since I’m adding a hop between client and modem, although I’m wondering if there are settings I could change to mitigate the tiny latency increase I’m seeing (do I need DNS servers specified on the switch? or will it always defer to my router’s settings?) Like maybe I have a slight misconfiguration...Anyway, the next thing is to figure out VLAN tagging and configure that to work with my router so that I can securely administer my home network + surveillance camera system. If I can figure out VLANs and get that working, this switch will have be a great purchase!So far so good, wish me luck! This crap ain’t easy to figure out...
