Store And Forward; External Ac/Dc Power Adapter - Allied Telesis AT-FS201 Installation Manual

Description

Store and Forward

The AT-FS20x and AT-FS202SC/FSx Series 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 full
packet is received, the switch will forward or discard the packet, depending on
its destination address and error status. This ensures that only error-free
packets destined for another segment will be transferred across the switch,
reducing 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 if 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 will discard CRC errors, misaligned, runt, and under-oversized
packets. When the packet has dribble bits at the end, the switch will truncate
to octet boundary and check for a good FCS 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.
