USER’S MANUAL

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 orbackbone computing environments in SME (small, medium enterprise) businesses. The DYNA-SWITCH/24 (Rev. 2.0) Switch features a “store-and-forward “ switching scheme. This allows the switch to auto-learn and store source address on a 4K-entry MAC address table. It also supports Class of Service functions. No manual configuration is necessary. The CoS function is included in the switch firmware and willoperate automatically when the switch is on.

Ethernet Switching Technology
Ethernet Switching Technology has dramatically boosted the total bandwidth of networks, eliminated congestion problems inherent with CarrierSense 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 bandwidth. Second, by reducing the collision domain to a single switch-port, which eliminated the need for carrier sensing. Third, byusing the store-and-forward technology’s approach of inspecting each packet to intercept corrupt or redundant data, switching eliminated unnecessary transmissions that slow a network. This is accomplished by employing address learning which replaced the inefficient receiving port. Auto-negotiation regulates the speed and duplex of each port, based on the capability of both devices. Flow-controlallows transmission from a 100Mbps node to a 10Mbps node without loss of data. Auto-negotiation and flow-control may require the disabling of some networking operations involving legacy equipment. Disabling the auto-negotiation is accomplished by fixing the speed or duplex of a port. Ethernet Switching Technology has supplied higher performance at costs lower than other solutions. Wider bandwidth, nocongestion, and the reduction in traffic is why switching is replacing expensive routers and inefficient hubs as the ultimate networking solution. Switching brings a whole new way of thinking to networking.
