Um eine Beschädigung des Gerätes zu vermeiden sollten Sie nur Zubehörteile verwenden, die vom Hersteller zugelassen sind. Verwenden Sie nur sichere Standorte und beachten Sie die Aufstellhinweise des Herstellers. Die Belüftungsöffnungen dienen zur Luftzirkulation die das Gerät vor Überhitzung schützt. [. . . ] The Switch with its rack size is specifically designed for network workgroups. The Switch provides immediate access to a rapidly growing network through a wide range of user-reliable functions. The Switch is ideal for deployment with multiple high-speed servers for shared bandwidth 10Mbps or 100Mbps workgroups. In 200Mbps full-duplex mode, any port can provide workstations with a congestion-free data pipe for simultaneous access to the server. As all ports support 200Mbps full duplex, the Switch can be cascaded from any port and to any number of switches. The Switch is a perfect choice for site planning to upgrade to Fast Ethernet in the future. Ethernet workgroups can connect to the Switch now, and change adapters and hubs anytime later without needing to change the Switch or reconfigure the network. The Switch combines dynamic memory allocation with store-and-forward switching to ensure that the buffer is effectively allocated for each port, while controlling the data flow between the transmit and receive nodes to guarantee against all possible packet loss. Other key features are: Twelve N-Way UTP/STP ports all come with auto-negotiation and operate at 10/100 Mbps for connection to servers and hubs. Uplink/MDI-II (media dependent interface) port for uplinking to another switch, hub or repeater. Please note that if you are using the Introduction 3 10/100 Fast Ethernet Switch User's Guide uplink port, you will not be able to use port one (1x) because these ports are logically connected. Performance Features · 10/100Mbps Auto-Negotiation and Auto-Sensing on All Ports · Full/half duplex operation for each port · 1. 3 Gbps Switching Fabric, Provides Wire-Speed Performance on All Ports · Parallel Store-and-forward Architecture Provides High-Speed Switching scheme · LEDs for Easy Recognition of the Switch Operating Status · Optional DMA Port for a 100BASE-FX SC type module (paired with Port 12) · Console Port for easy Troubleshooting and Management · Complete Frame Checking & Error Filtering 4 Introduction 10/100 Fast Ethernet Switch User's Guide 5 2 UNPACKING AND SETUP This chapter provides unpacking and setup information for the Switches. Unpacking Open the shipping carton of the Switch and carefully unpack its contents. The carton should contain the following items: One DES-1012 Fast Ethernet Switch One AC power cord This User's Guide Four rubber feet with adhesive backing Six screws and two L-type brackets for rack mounting If any item is found missing or damaged, please contact your local Reseller for replacement. Unpacking and Setup 5 10/100 Fast Ethernet Switch User's Guide Setup Consider the following when setting up the Switch: The power outlet should be within 1. 82 meters of the device. Visually inspect the power cord and see that it is fully secured to the AC power connector. Make sure that there is proper heat dissipation from and adequate ventilation around the Switch. Do not place heavy objects on the Switch. Rack Installation The Switch can be mounted in an EIA standard size, 19-inch rack, which can be placed in a wiring closet with other equipment. To install, attach the mounting brackets on the switch's front panel (one on each side) and secure them with the screws provided. Figure 1A, Attaching the mounting brackets to the Switch Then, use the screws provided with the equipment rack to mount the Switch in the rack. 6 Unpacking and Setup 10/100 Fast Ethernet Switch User's Guide Figure 1B, Installing the Switch in an equipment rack Power On The Switch can be used with AC power sources 100 to 240 VAC, 50 to 60 Hz. The power switch is located at the rear of the unit adjacent to the AC power connector and the system fan. To turn the Switch on, press the power switch to the on or "1" position. The Switch's power supply will adjust to the local power source automatically and may be turned on without having any or all LAN segment cables connected. LED Indicators After the switch is turned on, the LED indicators should respond as follows: The power LED indicator will be green. Unpacking and Setup 7 10/100 Fast Ethernet Switch User's Guide Power Failure As a precaution, the Switch should be turned OFF in case of a power failure. At all times, avoid leaving the Switch ON after the occurrence of a power failure. 8 Unpacking and Setup 10/100 Fast Ethernet Switch User's Guide 6 3 IDENTIFYING EXTERNAL COMPONENTS This chapter describes the front panel, rear panel and LED indicators of the Switch. Front Panel The front panel of the Switch consists of 12 (10/100 Mbps MDI-X) ports, one Uplink (MDI-II) port and LED indicators. Descriptions of the ports appear in the Introduction of this User's Guide. Figure2, Front panel view of the Switch Identifying External Components 9 10/100 Fast Ethernet Switch User's Guide Rear Panel The rear panel of the Switch consists of a power switch, an AC power connector, a system fan, a location for slide-in module, and a duplex-mode Dip switch.
