Chapter 2, Hardware Description Explicates the front panel, rear panel and LED indicators of the Switch. Lists the technical (general, physical and environmental, and performance) specifications of the Switch. [. . . ] Combines dynamic memory allocation with store-andforward switching to ensure that the buffer is effectively allocated for each port, while controlling the data flow 3 · · · between the transmit and receive nodes to guarantee against all possible packet loss. This minimizes dropped packets by sending out collision signals when the receiving buffer is full. 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. 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. 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. 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. The indicator panel is described in detail in the next chapter. Front Panel The figure below shows the front panels of the switches. 16-port 10/100M Fast Ethernet Switch (AOW-216) 24-port 10/100M Fast Ethernet Switch (AOW-224) LED Indicator Panel Refer to the next chapter for detailed information about each of the switch' s LED indicators. [. . . ] Using crossover cable When using crossover cable, the connection can be made from any ports of the Switch to any port of the Hub. Switch to Switch (other devices) The Switch can be connected to another switch or other devices (routers, bridges, etc. ) via a two-pair Category 3, 4, 5 UTP/STP straight or crossover cable. A. 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. [. . . ]
