Block architecture
Block architecture with SCALANCE XR-300 devices
The XR324-12M and XR324-4M handle 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.
