Note
The number of connected switches in󹪞uences the frame delay.
When a frame passes through the CSM 377, it is delayed by the store and forward function of the
switch
- with a 64 byte frame length by approx. 8 µs (at 100 Mbps)
- with a 1500 byte frame length by approx. 125 µs (at 100 Mbps)
This means that the more CSM 377 switches that a frame passes through, the higher the frame
delay will be.
