Number of frames per second At a frame length of

Note
The following applies to IE Switches X-300:
The number of IE Switches X-300 connected in a line influences the frame delay time. When
a frame passes through the switch, this is delayed by the Store&Forward function of the
IE Switch X-300 by the following values:
● at 64 bytes frame length: Delay of approx. 10 microseconds (at 100 Mbps)
● at 1500 bytes frame length: Delay of approx. 130 microseconds
(at 100 Mbps)
This means, the more IE Switches X-300 a frame runs through, the higher the frame delay.

Note
For a device to be used in PRP networks, it must be able to process a frame length of at least
1528 bytes (Jumbo Frames). This value is the maximum frame length including VLAN tag of
1522 bytes plus the length of the PRP trailer of 6 bytes. The following table shows the version
as of which the devices are PRP-compatible.
