The package also includes a RJ45 SFP module (S-RJ01) already pre-installed in the first port, so you can use the Ethernet in one of the ports right out of the box. If this is not necessary, remove it to have access to all five SFP ports to use the 1.25 Gbit fiber modules.

You need space for a system package and additional packages that you need to upgrade. After uploading newer versions of the packages to your router, you should have at least 2 MB free disk space. If you have less than 2MB of space left, do not try to upgrade! First uninstall any unnecessary packages and then update the rest.
Each router is configured at the factory with IP address 192.168.88.1/24 on Ethernet port1. The default user name is admin without password. After the first login, please create a new user with the password in the "full" group, log in again and remove the default admin user.
To update your software, you must download the latest package files (*.npk) from our website. Then connect to your router via FTP and upload the new packages to it using the binary transfer mode. Restart your router by issuing the command /system reboot.
