Product Description
This chapter describes the features of the AT-GS903SX Gigabit Ethernet
Switch.
Features
The AT-GS903SX is an unmanaged, Gigabit Ethernet Switch that provides
familiar Ethernet technology with high-speed access. It is a high-performance
switch that can be installed on the desktop, mounted on a wall, or installed in
a 19-inch rack. It presents an affordable, ideal solution to the bottlenecks that
can occur in networks where data-intensive applications and a proliferation of
new users is disrupting network throughput. The switch provides the following
features:
Ethernet, Fast Ethernet, and Gigabit Ethernet connectivity:
one 10/100Base-TX port with an RJ-45 connector, and three
1000Base-SX ports with SC connectors
A small 1.0U high, 13-inch enclosure for desktop, wall, or 19-inch
rack-mount installation
Half- or full-duplex operation and autonegotiation on the 10/100Mbps
port, full-duplex operation on the gigabit ports
Complies with IEEE 802.3u, IEEE 802.3ab, and IEEE 802.3z
specifications
Store-and-forward switching mode
Supports extended frame lengths up to 1536 bytes
12K MAC addresses with automatic learning and aging
Eight MB SGRAM for the data buffer of each port
LED indicators for Power, for port Link and Activity on the gigabit
ports, and for Full-duplex/Collision and Link/Activity on the
10/100Mbps port
One media-dependent interface (MDI) button on Port 4 (10/100Mbps)
for hub or PC connection
Internal autoranging power supply (100-120/200-240VAC)
