It is recommended to flash to “Partition 0”. The factory web GUI will show the following warning: Warning: The firmware version is v0.00.00-c0.0.00 The firmware image you are uploading is older than the current firmware of the switch. The device will reset back to default settings. Are you sure you want to proceed?" This is expected when flashing OpenWrt. After the initramfs image boots, flash the -sysupgrade using either the commandline or LuCI. Upgrading OpenWrt → generic.sysupgrade Debricking → generic.debrick Failsafe mode → failsafe_and_factory_reset Basic configuration → Basic configuration After flashing, proceed with this. Set up your Internet connection, configure wireless, configure USB port, etc. Specific Configuration Network interfaces The default network configuration is: Interface Name Description Default configuration switch LAN None switch.1 LAN 192.168.1.1/24 Switch Ports (for VLANs) Port Switch port lan1 - lan8 1 - 8 lan9 9F lan10 10F SFP Ports The SFP cages 9F and 10F share the same SCL line. Currently, there isn't a good way to model this in the OS. Thus, only one SFP port can be fully supported. Cage 10F is fully supported with an I2C bus and sfp handle. Linux automatically handles enabling or disabling the TX laser. Cage 9F is only partially supported, without the sfp handle. The default value of the tx-disable line is high (active). It is exported as a gpio, but the laser is off by default. To enable the laser: echo 0 > /sys/class/gpio/sff-p9-tx-disable/value Thus, both modules can be used for networking, but only 10F will be able to detect and identify a plugged in SFP module.
