Product Description

The dual-speed standalone Ethernet/Fast Ethernet hub is designed to
allow easy migration and integration between 10Mbps Ethernet and
100Mbps Fast Ethernet, while providing flexibility in cable
connections.

The device can operate with both IEEE 802.3 10BASE-T connections
(twisted-pair Ethernet operating at 10 megabits per second) and
IEEE 802.3u 100BASE-TX connections (twisted-pair Fast Ethernet
operating at 100 megabits per second). All of the twisted-pair ports
support Auto-Negotiation (NWay), allowing the hub to automatically
detect the speed of a network connection.

The hub has 8 ports and can have a single uplink connection to
another 100BASE-TX Class II Fast Ethernet repeater (hub or hub
stack).

On the hub, the 10Mbps and 100Mbps segments are separate and do
not intercommunicate. The device contains a built-in switch, making
it possible to transparently bridge between the 10Mbps and 100Mbps
segments.

Features

♦ Compatible with the IEEE 802.3 10BASE-T Ethernet and 802.3u

100BASE-TX Fast Ethernet industry standards for
interoperability with other Ethernet/Fast Ethernet network
devices

♦ Eight NWay RJ-45 ports for connecting stations to the network

♦ Built-in switching function supports bridging between 10Mbps

and 100Mbps segments

♦ LED indicators for power, collision, link, network activity, and

operating speed (10 or 100 Mbps)

♦ Auto-partitioning for network protection

♦ Data collision detection and handling

♦ Preamble regeneration, signal retiming

♦ Uplink port allows easy linking of two Fast Ethernet or four

Ethernet hub stacks to further expand your network

♦ External linear power adapter featured (output 7.5V/1A)

♦ Simple Plug and Play installation

♦ Compact size and light weight, ideal for SOHO, cubicle LANs

Unpacking

The carton should contain the following items:

♦ One dual-speed standalone hub
