A BOUT T HIS G UIDE Congratulations on your purchase of DSS-16+. This device integrates 100Mbps Fast Ethernet and 10Mbps Ethernet network capabilities in a highly flexible package. Purpose This guide discusses how to install your DSS-16+. Terms/Usage In this guide, the term “Switch” (first letter upper case) refers to your DSS16+, and ”switch” (first letter lower case) refers to other Ethernet switches. Overview of this User’s Guide Introduction. Describes DSS-16+ and its features.
I NTRODUCTION This chapter describes the features of DSS-16+ and some background information about Ethernet/Fast Ethernet switching technology. Fast Ethernet Technology The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks. A number of high-speed LAN technologies have been proposed to provide greater bandwidth and improve client/server response times.
Switching Technology Another approach to pushing beyond the limits of Ethernet technology is the development of switching technology. A switch bridges and transmits Ethernet packets at the MAC address level of the Ethernet protocol, among connected Ethernet or Fast Ethernet LAN segments. Switching is a cost-effective way of increasing the total network capacity available to users on a local area network.
Features This high performance DSS-16+ was designed for a network environment where traffic and the number of users increase continuously. DSS-16+, with their small, desktop size, was specifically design for small to middle workgroups. It provides immediate access to a rapidly growing network through a wide range of user-reliable functions. DSS-16+ is ideal for shared bandwidth 10Mbps or 100Mbps workgroups with multiple high-speed servers.
NWay Auto-negotiation for any port. This allows auto-sensing of speed (10/100Mbps) thereby providing you with automatic and flexible solutions for your network. IEEE 802.3x flow control for full-duplex mode operation. Back pressure flow control for half-duplex mode operation. Data Forwarding Rate (per port) at wire-speed for both 10Mbps and 100Mbps speed. Data Filtering Rate (per port) at wire-speed for both 10Mbps and 100Mbps speed; eliminates all error packets, runts, etc.
U NPACKING AND I NSTALLATION This chapter provides unpacking and setup information for DSS-16+. Unpacking Open the shipping cartons and carefully unpacks its contents. The carton should contain the following items: One 16-port 10/100M NWay Fast Ethernet Switch One external power adapter Four rubber feet to be used for shock cushioning User’s Guide If any item is found missing or damaged, please contact your local reseller for replacement.
Front Panel The figure below shows the front panels of DSS-16+. 16-port 10/100Mbps NWay Fast Ethernet Switch LED Indicator Panel Refer to the next chapter for detailed information about each LED indicator. Rear Panel Twisted-Pair Ports Use any of these ports to connect network devices (workstations, hubs, switches, etc.) to DSS-16+. These ports are MDI-X ports and you can use ordinary straight-through twisted-pair cables to connect PCs, workstations, and Servers to DSS-16+.
The Uplink port is a MDI-II port, which means you can connect this port to another device’s MDI-X port using an ordinary straight-through twisted-pair cable. Port 1 and the Uplink port is really the same port, except that their pin-outs are different. Do not use both Port 1 and the Uplink port at the same time. DC Power Jack: Power is supplied through an external AC power adapter. Check the technical specification section for information about the AC power input voltage.
The DSS-16+ blinks green when transmitting or receiving data on the 100Mbps network. This indicator lights amber when the port is connected to a 10Mbps device. The DSS-16+ blinks amber when transmitting or receiving data on the 10Mbps network. C ONNECTING T HE S WITCH This chapter describes how to connect DSS-16+ to your Fast Ethernet network. PC to Switch A PC can be connected to DSS-16+ via a two-pair Category 5 UTP/STP straight cables.
100Mbps connection. The connection is accomplished from the hub’s uplink (MDI-II) port to any of DSS-16+’s 1~16 (MDI-X) ports. A. 10BASE-T Hub For a 10BASE-T hub, DSS-16+ LED indicators should light up as the following: “FDX/COL” LED indicator is OFF. “LINK/ACT” LED indicator lights amber. B. 100BASE-TX Hub When connecting to a 100BASE-TX hub, DSS-16+ LED indicator should light up as the following: “FDX/COL” LED indicator is OFF. “LINK/ACT” LED indicator lights green.
bridges, etc.) via a two-pair Category 5 UTP/STP straight or crossover cable. Note: Use CAT5 (or better) cable for 100Mbps connection. A. Using straight cable When using straight cable, this is done from DSS-16+’s uplink (MDI-II) port (Switch A) to any of the 10Mbps or 100Mbps (MDI-X) port of the other switch (switch B) or other device.

Please review your network products for matching cable pin assignment. The following diagram and tables show the standard RJ-45 receptacle/connector and their pin assignments for the switch-tonetwork adapter card connection, and the straight / crossover cable for the switch-to-switch / hub / bridge connection.
