The Routerboard 750UP is a five port ethernet router and is passive PoE capable on all ports. The device is supported at least with Barrier Breaker (OpenWrt).
Supported Versions
Hardware Highlights
Installation
Similiar to the Routerboard 750.
- Prepare an OpenWrt Ramdisk Image (Target: AR7XX, Subtarget: Mikrotik NAND Flash) or use this
- Configure a TFTP and DHCP Server. For informations how to do this see Wolf's Tech Blog.
- Connect yourself via cable into Port 1 and start your DHCP/TFTP servers.
- Boot the Routerboard into TFTP-Mode by pressing the RES button for several seconds until ACT led is not blinking anymore.
- Plug a network cable into port 3 and flash openwrt into the flash memory:
- serve your self-build OpenWrt images via http:
$ python -m SimpleHTTPServer .or use this - telnet into the device:
$ telnet 192.168.1.1 - flash via wget2nand:
$ wget2nand http://your-ip:8080'' or ''$ wget2nand http://cholin.spline.de/freifunk/openwrt/rb750up/(you need internet connection on your device (via wan))
