A BOUT T HIS G UIDE This manual provide all the information you need of how to install and operate AOpen SOHO 10/100M Fast Ethernet Switch (AOW-605/AOW-608). Overview • Chapter 1, Introduction. Describes the AOpen SOHO Switches and its features. • Chapter 2, Hardware Description. Explains the front panel, rear panel and LED indicators of the Switch. • Chapter 3, Connecting the Switch. Describes how you can connect the Switch to your Ethernet network. • Chapter 4, Technical Specifications.
I NTRODUCTION This chapter describes the features of this AOpen SOHO Switch and some background information about Ethernet/Fast Ethernet switching technology. Fast Ethernet Technology A number of high-speed LAN technologies have been proposed to provide greater bandwidth and improve client/server response times. Among them, 100BASE-T (Fast Ethernet) provides a non-disruptive, smooth evolution from the current 10BASE-T technology. 100Mbps Fast Ethernet is a new standard specified by the IEEE 802.
The switch acts as a high-speed selective bridge between the individual segments. Without interfering with any other segments, it automatically forwards traffic that needs to go from one segment to another. By doing this the total network capacity is multiplied, while still maintaining the same network cabling and adapter cards. For Fast Ethernet networks, a switch is an effective way of eliminating problems of chaining hubs beyond the “two-repeater limit.
Key features are: • Store and forward switching scheme capability. As the result of complete frame checking and error frame filtering, this scheme prevents error packages from transmitting among segments. • NWay Auto-negotiation for any port. This allows for auto sensing of speed (10/100Mbps) thereby providing you with automatic and flexible solutions in your network connections. • Flow control for any port.
H ARDWARE D ESCRIPTION This section identifies all the major external components of the hub. Both the front and rear panels are shown, followed by a description of each panel feature. The indicator panel is described in detail in the next chapter. Front Panel The figure below shows the front panels of the switch.

using the MDI-X jack (described below). For more information about crossover connections. • Uplink Jack(s) (MDI-II): Use this jack to connect stations to the hub. This is MDI-II (Mediumdependent Interface, straight-wired) jack, which means you can connect the hub to a device with a MDI-X port using an ordinary straight-through cable, making a crossover cable unnecessary. LED Indicators • Power Indicator (PWR) This indicator lights green when the hub is receiving power, otherwise, it is off.

C ONNECTING T HE S WITCH This chapter explains how to connect the Switch to your Ethernet network. In each of the following figures, the 5port 10/100M SOHO Switch(AOW-605) is shown. PC to Switch A PC can be connected to the Switch via a two-pair Category 3, 4, 5 UTP/STP straight cable. The PC (equipped with a RJ-45 10/100Mbps phone jack) should be connected to any of the 5 ports (1x - 5x). The LED indicators for PC connection depends on the LAN card capabilities.
straight cable. The connection is accomplished from the hub uplink (MDI-II) port to any of the Switch (MDI-X) ports: 1x - 5x for the Switch. A. 10BASE-T Hub For a 10BASE-T hub, the Switch LED indicators should light up as the following: • “Full-Duplex/Collision” indicator is OFF. • “100LINK/ACT, 10LINK/ACT LED” indicator is light amber. B. 100BASE-TX Hub For a 100BASE-TX hub, the Switch LED indicators should light up as the following: • “Full-Duplex/Collision” LED indicator is OFF.
B. Using crossover cable When using crossover cable, the connection can be made from any (MDI-X) ports of the Switch to any port of the Hub. Switch to switch (other devices) This switch can be connected to another switch or other devices (routers, bridges, etc.) via a two-pair Category 3, 4, 5 UTP/STP straight or crossover cable. A.
Port Speed & Duplex Mode After plugging the selected cable to a specific port, the system uses auto-negotiation to determine the transmission mode for any new twisted-pair connection: If the attached device does not support autonegotiation or has auto-negotiation disabled, an autosensing process is initiated to select the speed and set the duplex mode to half-duplex.
