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. Press the power switch to the off or "0" position. When power is resumed, turn the Switch ON. 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. Location for slide-in module System Fan Dip switch for Duplex mode AC Power Connector Power switch Figure 3, Rear panel view of the Switch Slide-in Module Slot. Use this slot to install a optional 100Base-FX(SC type) DES-112FX slide-in module. The module can be used to provide a high speed link to the rest of your network. The detail specification of this module please see Appendix C. And when the slide-in module is fitted, port 12 automatically switches to become the slide-in module port. This fan is used to circulate air inside the Switch and also to dissipate heat. The sides of the system also provide heat vents to serve the same purpose. Do not block these openings, and leave adequate space at the rear and sides of the Switch for proper ventilation. Be reminded that without proper heat dissipation and air circulation, system components might overheat, which could lead to system failure. Use this Dip switch to set the duplex mode. Each port in the DES-1012 can be set for half duplex or full duplex mode. To set a port in full duplex mode, slide the corresponding switch up. To set it in half duplex mode, slide the corresponding switch down. AC Power Connector. This is a three-pronged connector that supports the power cord. [. . . ] However, it has a definite appeal to widespread LANs where cost of wiring is less important than the distance it delivers to Ethernet LANs-400 meters for half-duplex segments and 2 kilometers for full-duplex segments. The 100BASE-FX port requires one pair of 62. 5/125 micron fiber-optic cable. It services distance of up to 400 meters and supports full or halfduplex operation. It is an ideal solution for backbone connections. How to Install the DES-112FX 100BASE-FX module Unplug power code. [. . . ]
