Description

Store and Forward

The AT-FS20x switches support store and forward switching at Fast Ethernet full-wire speed in 100 Mbps, half- or full-duplex mode. Packets entering each port are stored in buffers. Once the packet is received, the switch forwards or discards the packet, depending on its destination address and error status.

This ensures that only error-free packets destined for another segment are transferred across the switch, reducing the network load. For example, if the packet entering from Port 1 is destined for an end-node on Port 2, the switch forwards the frame as long as the frame does not contain any errors. If the packet from Port 1 is destined for an end-node also connected to Port 1, the packet is discarded.

The switch discards CRC errors, misaligned, runt, and under or oversized packets. When the packet has dribble bits at the end, the switch truncates to the octet boundary and checks for a good CRC before forwarding.

External AC/DC Power Adapter

The power adapter supplies 12V DC to the switch. Allied Telesyn supplies an approved safety compliant AC power adapter for the 100 and 240V AC versions with an unregulated output of 12V DC.
