Block architecture

Block architecture of the SCALANCE XR-300M PoE
The XR‑300M PoE handles the Ethernet frame traffic of the 24 ports with the aid of three switch
blocks.
● The three switch blocks are connected in series (block 1 via block 2 to block 3).
● Gigabit wire speed is possible within a block (max. 8 ports per block).
● Between the blocks there is a bandwidth of 1 gigabit/s available,that must be shared by all
ports for frame traffic between the blocks.
When operating solely with Fast Ethernet (100 Mbps), the XR devices support full wire speed
via all blocks.
