the mounting rails above and below.

Installing media modules
The switch has 4 inputs for connecting media modules.
The number of connectible network segments depends on the number of
media modules installed. If the full 4 media modules with 8 ports each are
connected, then in addition to the ports of the basic board, you get a further
32 ports for connecting network segments.
The modular design of the device allows you to easily expand the network
yourself by installing the desired media modules.
The media modules can be installed in the devices, or de-installed, while the
network is operating (hot-swappable).
