Chapter 2: Overview Figure 2-2. Side panel of the switch (fan location). 2.4 Switch Architecture The switch transports multiple packets at wire-speed and low latency on all ports simultaneously. It operates in full-duplex mode on all ports to effectively double the bandwidth of each connection. This switch uses store-and-forward technology to ensure maximum data integrity. With this technology, the entire packet must be received into a buffer and checked for validity before being forwarded. Th
