LINOVISION Industrial 8 Ports Gigabit Managed PoE Switch with DC12~57V Input, L2 Management, RS485 Serial Port, DC 12/24V Output, BT 90W Output

This thing works pretty well for my RV setup with a bunch of PoE devices. You are going to want to buy a console cable because the ssh, telnet, et al. management methods they claim to have don’t actually work out of the box.I couldn’t actually get my computer to connect to the management website because my security firewall was flagging and blocking it (maybe because it’s in Chinese?). After I disabled it I was able to connect, enable https, and then I was able to continue to connect from there.There is zero documentation, although some similar managed switch models have documentation.It comes with OpenWRT and a bunch of custom scrips for managing things like the reset button. After I got console access from the console port, which will log you into OpenWRT as root automatically, I disabled the OpenSSH service they had running (which for some reason was throwing errors trying to access the shadow file), and enabled dropbear for ssh access.From there telnet magically started working. There’s some custom interface I’m not familiar with, but it resembles a Cisco switch config that you would telnet into.A bunch of things you may want to lock down like telnet and SNMP v1&v2 with default community strings “public” and “private”.I haven’t had any problems with the PoE, that’s been working great.Device gets a little warm but not too hot, basically has a giant heat sync enclosure. Built very solid.This device appears to be branded by Linovision, Hinovision, but there are multiple places in files saying Utepo Data Communcation Co., Ltd.Suggestion to the seller / manufacturer, please provide on your website the documentation AND the firmware to flash the device!Lastly, device came running OpenWRT designated_driver for mvebu64 hardware. ‘opkg update’ doesn’t work since OpenWRT has reorganized their files so the distfeed.conf doesn’t point to the correct place.
