AT-FS708 and AT-FS708E Switches Installation Guide

Power Supply

The AT-FS708 uses a 40W universal internal switching power supply with 100
to 120 VAC, or 200 to 240 VAC, 50/60 Hz input rating.
Allied Telesyn ships power cords with the units to the U.S., Continental
Europe, and the U.K.
The AT-FS708E uses an external power adapter.

Required Voltage

The switches require input of 100 to 230 VAC. Maximum power consumption
is 50W maximum.

Auto-Negotiation

The 10/100 Mbps ports are capable of auto-negotiation:
The ports automatically adapt to the wire speed (10 or 100 Mbps) and duplex
transmission (half- or full-duplex) supported by the linked device without user
reconfiguration.
Auto-negotiation is an optional function of the IEEE 802.3u Fast Ethernet
standard that enables devices (switches) to automatically exchange
information over a link about their speed and duplex abilities. 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 multispeed devices at 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-negotiation protocol also includes automatic negotiation 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 without any intervention
from a network administrator.
