Step 2. Choose Cisco Network Devices Your next task is to choose the appropriate network interconnect devices for the network in question. As mentioned above, the company works with Cisco products and all hubs, switches, and routers that will be on the network must be Cisco devices. The only exception is Router 3 (see Figure 1) which is a Windows Server 2012R2 router. Your instructor will provide you with the necessary documentation for the following Cisco products: 1600, 2500, 3600, 4500-M, 4700-M and 7200 series routers. The 1500 and 1528 series microconcentrators Fasthub 100, 200 and 300 series concentrators. Important: Addition to the documentation For all hubs that have an uplink port, if the uplink is used, the corresponding regular port should not be used. For example, if the uplink port on FastHub 116T is used, port 16 should not be used. If you use both ports at the same time, the effect is to deactivate both ports. Using the documentation provided by your instructor and the appendix above, select the appropriate hubs and routers for your network (eg FastHub 216T; 2504 Router, etc.) according to the constraints and guidelines below: Each of the hubs and routers shown in Figure 1 is a single device, not a stack of devices. All devices on segments A, B, G, H, I, and J require Fast Ethernet (100BaseT) connections, All devices on segment L are 10BaseT devices, and all other segments have a mix of 10BaseT devices and 100BaseT. Router 4 must support an ISDN connection to the Internet as shown in Figure 1. The Cisco device model chosen for this router must have an ISDN interface on the router and not simply supported by the addition of a card. The lowest production model that meets the criteria must be chosen. For example, if a 2500 series router and a 3600 series router meet the criteria, you should choose the 2500 series and not the other way around. If Model 2501 and Model 2502 meet the criteria, you must choose Model 2501.
