Gigabit Ethernet technology allows signal transmission at the rate of one
gigabit per second (1 Gbps, or 1000 Mbps), while continuing to support
IEEE 802.3 CSMA/CD local area networks. Using this technology, you can
add gigabit bandwidth to critical areas of a network and fully leverage
investments in Ethernet and Fast Ethernet products.

General Description

II Hub 1000 SX Gigabit Ethernet full-duplex
repeater (part number 3C510-SX) combines the low cost and simplicity
of a hub with the high performance and efficient throughput of a switch.
You can use the Hub 1000 SX to:
■
Aggregate servers
■
Aggregate 10/100 Mbps switches
■ Provide gigabit bandwidth to a power workgroup that is running a
high-bandwidth application such as medical imaging, video editing,
film postproduction, CAD/CAM, or digital prepress
The Hub 1000 SX is an eight-port repeater. All ports transmit and receive
at a speed of one gigabit per second. The hub forwards all incoming
packets (without filtering them) to all links except the originating
link, thus providing a shared bandwidth domain. Like a switch, the
Hub 1000 SX uses full-duplex ports and packet flow control to increase
bandwidth and ensure reliable performance.
The hub is ready to use and requires no configuration. However, some
configuration options are available through the console interface for use
in exceptional cases.
The Hub 1000 SX is part of the 3Com SuperStack II system and can
be used with the SuperStack II Advanced Redundant Power System
(Advanced RPS) and the SuperStack II Uninterruptible Power System (UPS),
which provide fail-safe operation and a constant power supply.
