1. Introduction Welcome to the World of Micro-Networking. Communication and Sharing information is a crucial component of business today. The need for instant electronic communication between employees, vendors and customers, along with access to information sources and sharing of equipment, has necessitated connectivity to even the most remote office location. The MIL-S501xx is a compact desktop size switch that is an ideal solution for distributed network user.
These fiber connectors are ST, SC multi-mode, SC single-mode, and MT-RJ. The fiber port can be used to connect to a remote site up to 2 kilometers using multi-mode fiber or up to 60 kilometers with SC single-mode fiber.

2. Hardware Description This Section mainly describes the hardware of the MIL-S501xx. The MIL-S501xx is a compact palm size switch (6.5 inches) with 5x 10/100 N-Way UTP switch ports plus one 100Baes-FX fiber port. The physical dimensions of the MIL-S501xx are: 165mm x 100mm x 24mm 6.50 in. x 3.94 in. x .95 in. Front Panel The LED indicators are located on the frond panel of the switch. They provide a real-time indication of systematic operation status.
LED Indicators The following table provides descriptions of the LED statuses and meaning. LED Power Status Color Description On Green The power of unit is On On Green The port is operating at the speed of 100Mbps. Off In 10Mbps mode or no device attached 100M On LNK / ACT Blinks Off On FDX / COL Blinks Off Green The port is successfully connecting with the device. The port is receiving or transmitting data. No device attached. Yellow The port is operating in Full-duplex mode.
Rear Panel The Rear Panel of the MIL-S501xx consists of 5x 10/100 N-Way UTP switch ports, Uplink Port, one 100Base-FX fiber port, 1 DIPswitch to select fiber port full-duplex or half-duplex mode, and DC power connector. There are five types of fiber connectors available for the convenience of your connectivity. These fiber connectors are ST, SC MMF, SC SMF, and MT-RJ.

n RJ-45 Ports: Five 10/100 N-Way auto-sensing for 10Base-T or 100Baes-TX connections. n 100Base-FX Fiber Port: There are 5 types of fiber connectors available for the MIL-S501xx as shown above. The distance for fiber cabling can be extended up to 2 kilometers for multi-mode fiber and up to 70 kilometers for single-mode fiber. n DIPswitch: the DIPswitch is to select Full duplex or Hallduplex mode for the fiber port. DIP 1 UP: Fiber port operates on Full Duplex mode.
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. Desktop Application The MIL-S501xx is designed to be a compact desktop size switch that is an ideal solution for small workgroup.
Collapsed Backbone Application You can use Uplink port of the MIL-S501xx to connect with another hub or switch to 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 60Km with single-mode fiber. The Up-link Port is the same port as port 1, but the pin assignment has been designed to contain crossover pinout.
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 Link indicator does not light up after making a connection. You may check whether network interface (e.g., a network adapter card on the attached device), network cable, or switch port is defective or not. Verify that the switch and attached device are power on.
n Cabling A. RJ-45 ports: Use unshielded twisted-pair (UTP) or shield/screened unshielded twisted-pair (S-UTP) cable for RJ45 connections: Category 3, 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-mode connector type must use 62.5/125 um multi-mode fiber cable. You can connect two devices over a 2-kilometer distance.

Appendix 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 of repeater Hubs is two. This is due to the accelerated Ethernet data rate, which requires a reduction in network diameter in order to detect collisions.
*100BaseT4 for four-pair voice and data grade Category 3,4 or 5 UTP *100BaseFX for 2-strand multimode fiber Media Access Control (MAC) Layer The MAC layer is based on the same CSMA/CD protocol as 10Mbps Ethernet. The only difference is that it runs 10times faster. Media Independent Interface (MII) Layer The MII is a new specification that defines a standard interface between the MAC layer and any of the three physical layers (100BaseTX, 100BaseT4 or 100BaseFX).
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 a shortage of bandwidth, the introduction of a 10Mbps switch will only move the bottleneck from the hub to the 10Mbps-server pipe.
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 on network, packets can be switched between different network speeds.
