3.4 Description of the product
Options for slots 5 and 6 (SCALANCE X408-2)
Slots 5 and 6 of the basic device each have two RJ-45 jacks for connecting TP cables. The
possible data transmission rates on electrical connections are 10, 100, or 1000 Mbps. An
optical gigabit or Fast Ethernet module in slot 5 and/or 6 allows data transmission with
multimode or single mode FOC. In this case, the two RJ-45 jacks below the module can no
longer be used.

● In display mode B, the fixed transmission rate is displayed.
● In display mode C, the full duplex mode is always displayed.
