Chapter 2, Hardware Description Explicates the front panel, rear panel and LED indicators of the Switch. Explains how you can connect the Switch to your Ethernet network. [. . . ] Data forwarding rate per port is at wire-speed for 100Mbps speed. Data forwarding rate per port is at wire-speed for 10Mbps speed. Up to 16K active MAC address entry table with selflearning and table-aging for 16-port model(AOW-216), up to 24K active MAC address entry table with self-learning and table-aging for 24-port model(AOW-224). 1 MB RAM buffer per device for 16-port model(AOW-216), and 1. 5MB RAM buffer per device for 24-port model(AOW224) · · · · HARDWARE INSTALLATION The site where you install the hub stack may greatly affect its performance. Before installing your switch, consider the following suggestions: · Install the stack in a fairly cool and dry place. See the 4 product specification for the acceptable temperature and humidity operating ranges. · Install the stack in a site free from strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight. Leave at least 10cm of space at the front and rear of the switch 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 next section, RackMounting. When installing the hub stack 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. 5 Then, use screws provided with the equipment rack to mount each switch in the rack. 6 100Base-FX Module Installation To install any of the modules: (Includes SC or ST type connectors) 1. Locate the module slot in the switch' s rear panel. Using a screwdriver, undo the two screws and remove the dust cover on the module slot. Holding the module component-side up and connector-side in, gently slide the module along the guides and seat it in the internal connector. Using a screwdriver, replace the two screws and tighten until snug. We recommend that you retain the dust cover in case you need to remove the module for an extended period sometime in the future. For AOW-216 (16-port switch), port 9 and the 100BASE-FX port 7 is really the same port. Do not use both Port 9 and the 100BASE-FX port at the same time. For AOW-224 (24-port switch), port 5 and the 100BASE-FX port is really the same port. Do not use both Port 5 and the 100BASE-FX port at the same time. 8 HARDWARE DESCRIPTION This section identifies all the major external components of the switch. Both the front and rear panels are shown, followed by a description of each panel feature. [. . . ] Using straight cable When using straight cable, this is done from the uplink (MDI-II) port of the Switch (Switch A) to any of the 10Mbps or 100Mbps (MDI-X) port of the other switch (switch B) or other devices. B. Using crossover cable When using crossover cable, this is done from any (MDI-X) port of the Switch (Switch A) to any of the 10Mbps, 100Mbps (MDIX) port of the other switch (switch B) or other devices. The "100M LINK/ACT, 10M LINK/ACT" LED indicator light green for hookup to 100Mbps speed or light amber for hookup to 10Mbps speed. The "10/100M FDX, 10/100M COL" LED indicator depends upon LAN card capabilities for full-duplex or half-duplex 2. 15 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 auto-negotiation or has auto-negotiation disabled, an auto sensing process will be initiated to select the speed and set the duplex mode to halfduplex. 16 TECHNICAL SPECIFICATION General Standards IEEE 802. 3 10Base-T Ethernet IEEE 802. 3u 100 Base-TX Fast Ethernet ANSI/IEEE 802. 3 NWay auto-negotiation Protocol Data Transfer Rate Topology Network Cables CSMA/CD Ethernet: 10Mbps (half duplex) 20Mbps (full duplex) Fast Ethernet: 100Mbps (half duplex) 200Mbps (full duplex) Star 10BASET: 2-pair UTP Cat.
