11 n RJ-45 Ports: Five 10/100 N-Way auto-sensing for 10Base-T or 100Baes-TX connections. n Uplink Port: One uplink port to cascade to a hub or switch, with the maximum distance between the switch to another device is 100 meters. n 100Base-FX Fiber Port: There are 5 types of fiber connectors available for the MIL-S501xx as shown above. The distance [...]

12 3. Network Application This section provides you a few samples of network topology in which the Switch is used. In general, the MIL-S501xx is designed to be used as a desktop or segment switch. The Switch automatically learns node addresses, which are subsequently used to filter and forward all traffic based on the destination address. D esktop [...]

13 Collapsed Backbone Application You can use Uplink port of the MIL-S501xx to connect with another hub or switch t o interconnect each of your small-switched workgroups to form a larger switched network . You can also use fiber ports to connect switches. The distance between two switches via fiber cable can be up to 2Km with multi-mode fiber or 70[...]

14 4. Trouble Shooting The Switch can be easily monitored through panel indicators to assist in identifying problems. This section describes common problems you may encounter and where you can find possible solutions. n Diagnosing LED Indicator If L ink indicator does not light up after making a connection. You may check whether network interface ([...]

15 n Cabling A. RJ-45 ports: Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable for RJ-45 connections: Category3, 4 or 5 cable for 10Mbps connections or Category 5 cable for 100Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet). B. 100Base-FX fiber port: Fiber multi-[...]

17 A ppendix What is Switch Ethernet ? With a high-speed backplane, it is possible to have all ports communicating at wire speed with minimal latency and low packet loss A-1. 100Base-T Technology Review The 100BaseT standard retains 10BaseT's critical 100-meter maximum cable length between the hub and desktop. With 100BaseT, the maximum number[...]

The only difference is that it runs 10times faster. Media Independent Interface (MII) Layer The MII is a new specification that de[...]

19 A switch is an intranetwork device designed to increase performance through LAN segmentation. Switching uses microsegmentation to isolate traffic. Upon arrival at the hub, a packet's destination address is read and the packet is sent directly to the relevant port - not to all ports, as it would be with a repeater. For networks experiencing [...]

20 Store-and-Forward Switching Store-and-forward switching is the best choice to keep the network effective and reliable. Store-and-forward provides excellent error-checking function. For example, CRC, runt and collision filter. Store-and-Forward reads the entire data packet, verifies the packet and sends it to the destination port. No bad packets [...]
