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)
