Introduction UNICOM’s DYNA-SWITCH/24 (Rev. 2.0) is a 24-port 10/100BASE-TX Switch that can be used to build high-performance switched workgroup networks. This switch is a store-and-forward device that offers low latency for high-speed networking and is targeted at workgroup, department or backbone computing environments in SME (small, medium enterprise) businesses. The DYNA-SWITCH/24 (Rev. 2.0) Switch features a “store-and-forward “

Ethernet Switching Technology Ethernet Switching Technology has dramatically boosted the total bandwidth of networks, eliminated congestion problems inherent with Carrier Sense multiple access with Collision Detection (CSMA/CD) protocol, and greatly reduced unnecessary transmissions. This revolutionized networking. First, by allowing two-way, simultaneous transmissions over the same port (Full-duplex), which essentially doubled the b

Hardware Description This section describes the hardware of the DYNA-SWITCH/24 and gives a physical and functional overview of this Switch. Physical Dimension The physical dimension of the DYNA-SWITCH/24 is 440mmx 120 mm x 44mm (L x W x H) Front Panel The front panel of the DYNA-SWITCH/24 consists of (24) 10/100Base-TX RJ-45 ports. The LED Indicators are also located on the front panel of the Switch. Front panel of the DYNA-SWITCH/24 (Rev. 2.0) RJ-45 ports (Auto

Rear Panel The 3-pronged power plug is located at the rear panel of the DYNA-SWITCH/24 as shown in the figure. The switch will work with AC in the 100-240V AC, 50-60Hz range. The rear panel of the DYNA-SWITCH/24 Desktop Installation Set the switch on a sufficiently large flat space with a power outlet nearby. The surface should be clean, smooth, level and sturdy. Make sure there is enough clearance around the Switch to allow air circulation and the attachment of cables

Rack-mounted Installation The DYNA-SWITCH/24 comes with a rack-mounting kit (not a standard option for this switch) and can be mounted in any EIA standard sized, 19" rack. The Switch can then be placed in a wiring closet with other equipment. Perform the following steps to rack mount the switch: 1. Position one bracket to align with the holes on one side of the switch and secure it with the smaller bracket screws. Then attach the rem

Network Application This section provides a few samples of network topology in which the switch is used. The DYNA-SWITCH/24 (Rev. 2.0) is designed to be used as a segment switch. With its large address table (4K MAC address) and high performance, it is ideal for interconnecting networking segments. PC, workstations, and servers can communicate with each other by directly connecting with the DYNA-SWITCH/24. The switch automatically learns nodes address, which are subsequently used

Segment Bridge In enterprise networks where large data broadcasts are constantly processed, this switch is an ideal way for departmental users to connect to the corporate backbone. In the illustration below, two Ethernet switches, with PCs, a print server, and a local server attached, are connected to the DYNA-SWITCH/24. Each device in this network can communicate with the others through the DYNA-SWITCH/24. Connecting servers to the Switch allows other users to access the server’s

The packet with a 0~3 precedence value will flow to the low queue and 4~7 valued packets will flow to the high queue. It also supports weight round ration for high and low queue. The rate is 4:1 (4 high queue packets then 1 low queue packet) [Note] The CoS function is included in the switch firmware and will operate automatically when the switch is on.
