Power Supply
The switch uses a 40W universal internal switching power supply with 100 to
120 VAC, or 200 to 240 VAC, 50/60 Hz input rating. The switch requires input
of 100 to 240 VAC. Maximum power consumption is 20W. Allied Telesyn ships
power cords with the units to the U.S., Continental Europe, and the U.K.
Auto-Negotiation
Auto-negotiation is an optional function of the IEEE 802.3u Fast Ethernet
standard that enables devices 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.
All nine 10/100 Mbps ports on the switch are capable of auto-negotiation. This
means these ports automatically adapt to the wire speed (10 or 100 Mbps) and
duplex transmission (half- or full-) supported by the link without user
reconfiguration.
