Anleitung Zusammenfassung
Installation The site where you install the Switch stack may greatly affect its performance. Use the following guidelines when installing the Switch. • Install the Switch in a cool and dry place. See Specifications for the acceptable temperature and humidity operating ranges. • Install the Switch in a site free from strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight. • Leave at least 10 cm of space at the front and rear of the hub for ventilation. • Install the Switch on a sturdy, level surface that can support its weight, or in an EIA standard-size equipment rack. For information on rack installation, see the Rack Mounting section. AirLink+ 11 24-Port 10/100Mbps Ethernet Switch User Guide When installing the Switch on a level surface, attach the rubber feet to the bottom of each device. The rubber feet cushion the hub and protect the hub case from scratching. Rack Mounting The switch can be mounted in an EIA standard-size, 19-inch rack, which can be placed in a wiring closet with other equipment. Attach the mounting brackets at the switch's front panel (one on each side), and secure them with the provided screws (see Figure 1). Figure 1. Attach Brackets to Switch 12 AirLink+ 24-Port 10/100Mbps Ethernet Switch User Guide Then, use screws provided with the equipment rack to mount each switch in the rack (see Figure 2). Figure 2. Attach Switch to Rack External Components This section identifies all the major external components of the switch. Front Panel Figure 3 shows the front panels of the switch.

Otherwise, it is off. • Link/Activity (green) Link/Activity (green)Link/Activity (green)Link/Activity (green)Link/Activity (green)Link/Activity (green).This indicator lights up green when the port is connected to a Fast Ethernet or Ethernet station. If this indicator is blinking green, the Switch is transmitting or receiving data. • 100 Mbps (green) 100 Mbps (green)100 Mbps (green)100 Mbps (green)100 Mbps (green)100 Mbps (green).This indicator lights up green when the port is connected to a 100-Mbps Fast Ethernet station. Otherwise, the LED is off when the port is connected to a 10-Mbps Ethernet station. Twisted-Pair Ports Twisted-pair ports support automatic MDI/MDIX crossover detection function gives true 'plug and play' capability without the need of confusing crossover cables or crossover ports. With the Auto-MDI function, you just need to plug-in the network cable to the hub directly and no need to care if the AirLink+ 15 24-Port 10/100Mbps Ethernet Switch User Guide end node is Network Interface Card (NIC) or switches and hubs. Rear Panel The AC power connector is located on the rear panel and is a three-pronged connector that supports the power cord (see Figure 5). Plug in the female connector of the provided power cord into this connector, and the male into a power outlet. The Switch supports input voltages from 100 to 240 AC at 50 to 60 Hz. Figure 5.
