AT-3714F, AT-3726 Hardware
Description
The AT-3714F switch provides 12 Ethernet 10Base-FL ports and one
built-in 100Base-FX port.The AT-3726 switch is a standalone,
managed Ethernet switch that provides 24 10Base-T ports and one
built-in 10/100Base-TX port.Both switches include a 100Base-X slot
that can be configured with an optional 10/100Base-TX or
100Base-FX port.
The switches are intended for connections to the desktop as well as
workgroup applications and implement direct high-speed server
and backbone connections.Full duplex capability on all ports
eliminatescollisionsandprovidesupto20Mbpsonthe10Baseports
and up to 200 Mbps of bandwidth on the 100Base ports to servers,
routers,and other switches.With built-in management,this switch
provides seamless management capability such as SNMP.

Hardware Features
The switches have the following major hardware features:
❑
Full duplex capability on all ports eliminates collisions and
provides up to 20 Mbps on the 10Base ports and up to 200
Mbps of bandwidth on the 100Base ports to servers,routers,
and other switches
❑
Auto-negotiation on all 10BaseT and 10/100BaseTX ports in
compliance with IEEE 802.3u
❑
Port mirroring
❑
Non-blocking, clear-channel architecture delivers wire-speed
switching and up to 880 Mbps aggregate bandwidth for
exceptional performance (AT-3726); 640Mbps for AT-3714F
❑
Shared memory architecture with 1M of packet buffers per
ASIC chip (two ASICs for AT-3726; one ASIC for AT-3714F)
❑

❑
In-band Telnet capability for switch management
❑
Out-of-band capability with RS232 connector for switch
management
❑
Flash memory for convenient upgrades
Network Management Features
The following lists the switch’s major network management features.
❑SNMP Management Information Base (MIB) II, SNMP MIB
extensions, Bridging MIB (RFC 1493), and Telnet support
deliver comprehensive in-band management
❑Local Omega, a menu-based management console, provides
detailed out-of-band management
❑IEEE 802.1d Spanning Tree Protocol support for redundant
backbone connections and loop-free networks simplifies
configuration and improves fault tolerance
MAC Addressing
TheswitchhashardwarebasesupportwithExternalAddressLookup
Engine (EALE) for static entries and self-learning of active MAC
addresses.The switch can support up to 1954 MAC addresses.
Store and
Forward/
Cut-Through
(fragment-free)
Modes
With store and forward or cut-through (fragment-free) switching
modes,network administrators can optimize performance and
enable full-error checking.
The store and forward mode (default), works in the following way.
First, as the packet is being received, it is placed in a buffer and held
there until the entire packet is received. The packet is also being
checked for errors and is not forwarded unless the entire packet is
error-free. This mode is automatic when data is exchanged between
10Base and 100Base ports.

AT-3714F, AT-3726 Hardware Description
1-4
With the Cut-through (fragment-free) method,the switch starts to
forward the incoming packet to its destination while the packet is
still being received.Cut-through (fragment-free) provides low
latency for forwarding frames and also filtering fragment frames by
not transmitting a frame until 64 bytes have been received by the
switch.In Cut-through (fragment-free) mode,fragment frames or
runts and short frames (frames less than 64 bytes) are filtered,thus
preventing error frames from propagating throughout the network
causing congestion.
Select the Cut-through (fragment-free) method if you are running
time-sensitive applications because it provides lower latency
through the switch.
Transmit Pacing
Transmitpacingisenabledonaperportbasis.Whentransmitpacing
is enabled,the switch alters its transmission routine during heavy
network activity.When the switch senses heavy traffic,it alters its
transmission routing by intentionally inserting additional delay
between transmission attempts.This added delay reduces collision
rates,thus reducing the number of transmission attempts,which
helps reduce CPU utilization,lightens overall network traffic,and
allows the network time to normalize before attempting
transmission.
Ifthisadditionaldelayis not applied,the switchattemptstotransmit
on an overloaded network,increasing the number of unsuccessful
transmission attempts.
For detailed information concerning software and management
features,see the“AT- S20 User’s Guide”located on AlliedTelesyn’s
website at alliedtelesyn.com/manuals.htm.
Mirror Port The switch has a dedicated Mirror port.Administrators can use the
Omega software to configure the Mirror port and modes.The Mirror
port can monitor traffic on any 10Mbps port,but only one port at a
time.An extended LANalyzer or an RMON probe can be connected
to the port mirroring connector using a standard Category 3 UTP
cable.
In full duplex mode the user needs to determine if they want to
monitorTX oronlyRXdata,butinonlyonedirectionatatime.Inhalf
duplex mode,both RX/TX can be monitored simultaneously.

RS232
Connector The RS232 connector provides out-of-band management via a
VT-100 terminal or MS-Windows’VTERM terminal emulation using a
straight-through cable.
Reset Button This recessed button can be activated using the tip of a ball point
pen to run power-on self test.
AC Power
Connector The switch has a single power supply,which has autoswitch AC
inputs.The input voltage range is from 120-240VAC,50/60 Hz.
