INTRODUCTION

	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.
Hub 1000 SX	The 3Com® SuperStack® II Hub 1000 SX Gigabit Ethernet full-duplex
General Description	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.
