Product Description

Common Major Features

These switch es come w it h the following com mon features:

❑

IEEE 802.3 and IEEE 802.3u compliant

❑

RJ-45 ports tha t can be connected/disconn ected without powering off
the switch

❑

Store and forward switching at full-wire speed (14,880 packets per
second on 10 Mbps ports and 148,8 80 packets per se cond on 100 Mbps
ports)

❑

Media-dependent interface (MDI) on Port 8 MDI for hub con nection or
Port 8 MDI-X for PC connection

❑

Support for up to 17K MAC addresses

❑

Internal power supply (100-240 VAC) for AT-FS708, or external power
adapter for AT-FS708E

❑

Desktop or wall-mount

The switch models described in this guide complement the other Allied
Telesyn Fast Ethernet products, providing sim ple, cost-effective solutions for
switching between 10 and 100 Mbps. Easy to install, simply connect yo ur
10Base-T or 100Base-TX station ports, and plug in the power.

Figure 1 and Figure 2 show the front panels of the switches.

AT-FS708 and AT-F S708E Ins tall at ion Guide

Power Supply

The AT-FS708 uses a universal internal switching power supply with 100 to
240 VAC, 50/60 Hz input rating. Allied Telesyn ships power cords with the
units to the U.S., Australia, Continental Europe, and the U.K. The
AT-FS708E uses an external power adapter.

Required Voltage

The switches require input of 100 to 240 VAC. Maximum power consumption
is 8.0 W maximum for AT-FS708, and 8.5 W for AT-FS708E.

Auto-Negotiation

The 10/100 Mbps ports are capable of aut o-negotiation:
The ports automatically adapt to the wire speed (10 or 100 Mbps) and duplex

transmission (h alf- or full-d uplex) su pported by th e linked de vice wit hout us er
reconfiguration.

Auto-negotiation is an optional function of the IEEE 802.3u Fast Ethernet
standard that enables devices (switches) to automatica lly exchan ge
information over a link about their speed and duplex abilitie s. This allows
devices to perform automatic configurations to achieve the maximum common
level of operation over a link. Auto-negotiation can provide automatic speed
matching for mu lt ispeed device s a t each end of a link. Multispeed Ethernet
interfaces can then take advantage of the highest speed offered by the 10/100
ports on the switch.

The auto-neg otiation protocol also includes au tomatic negotia tion of duplex
mode, allowing auto-negotiation-capable end-system devices to not only
configure the speed but also change to full-duplex for even higher traffic
throughput. This is particularly useful in environments where NICs are being
replaced or desktop workstations are moved. Each time a new device is
connected to a switch’s port or a device is moved from one port to another,
auto-negotiation will automatically reconfigure each port with o ut an y
intervention from a network administrator.
