This chapter describes the hardware features of the following
products:
❑
The base switch models: AT-FS718 and AT-FS724
❑
The uplink options, also called media dependent adapters
(MDAs): AT-A10 and AT-A11.
7KH#%DVH#6ZLWFK#0RGHOV
The AT-FS718 and AT-FS724 switches are standalone, unmanaged
Fast Ethernet switches that provide 16 or 24 10Base-T/100Base-TX
station ports. The AT-FS718 additionally provides uplink options of
up to two 100Base-TX or 100Base-FX ports for backbone
connectivity.
They are primarily intended for connections to the desktop as well as
workgroup applications. The AT-FS718, when populated with
optional uplink ports, implements direct high-speed server and
backbone connections. Full-duplex capability on all ports eliminate
collisions and provide up to 200 Mbps of bandwidth per port to
servers, routers, and other switches. The auto-negotiating ports
allow connectivity to devices operating at 10 Mbps or 100 Mbps
speeds.

❑
Two slots, Port A and Port B, for optional
uplink connectivity to either 100Base-TX or

The switches have the following common hardware features:
❑
Half- or full-duplex operation on all switched ports delivering
up to 200 Mbps of bandwidth to servers, routers, or other
switches
❑
Auto-negotiation on all 10Base-T/100Base-TX ports for speed
and duplex in compliance with IEEE 802.3u specifications
❑
Non-blocking, clear-channel architecture delivers wire-speed
switching and up to 2.4 Gbps aggregate bandwidth for
exceptional performance
❑
Shared memory architecture with 512kb memory per 4 ports
❑
Store-and-forward switching mode, or, for 100 Mbps ports
only, fragment-free cut-through switching mode
❑
Packet buffer memory of 3.0 MB for the AT-FS718 and 3.5 MB
for the AT-FS724
❑
8 MB DRAM and 2 MB Flash memory for software updates
❑
RS232 connector for port configuration, and diagnostics or
software updates.

+DUGZDUH#'HVFULSWLRQ
6ZLWFKLQJ#0RGHV
Each switch port has the following user-selectable switching modes:
❑
Store-and-forward (default)
❑
Fragment-free cut-through for 100 Mbps ports
Network administrators can configure the sending port with the
appropriate switching mode to optimize performance and enable
full-error checking. The modes reduce network bottlenecks by
offering low latency wire rate switching for the port.
With the store and forward method, the port waits to receive an
entire packet before forwarding it to its destination. This method
ensures that packets being forwarded are free of errors. The store
and forward mode (default) is automatic when data is exchanged
between 10Base-T and 100Base-TX ports.
With the cut-through method (for 100 Mbps ports only), the port
starts to forward the packet once the packet has exceeded the
smallest size (64 bytes), therefore filtering fragment frames or runts
(frames less than 64 bytes). This method provides low latency for
forwarding frames and also provides some network error protection.
Switching modes are part of the port configuration that is selected
using a terminal connected to the RS232 connector. See “Port
Configuration” on page2-12 for details of port configuration.
