AT-GS950/48 Gigabit Ethernet WebSmart Switch Installation Guide Ethernet Switching Basics An Ethernet switch interconnects network devices, such as workstations, printers, routers, and other Ethernet switches, so that they can communicate with each other by sending and receiving Ethernet frames. MAC Address Table Every hardware device on your network has a unique MAC address. This address is assigned to the device by the device’s manufacturer.
Chapter 1: Overview Duplex Mode Duplex mode refers to how an end node receives and transmits data. If an end node can receive or transmit data, but not both simultaneously, it is operating in what is referred to as half-duplex mode. If an end node can both receive and transmit data simultaneously, the end node is operating in full-duplex mode. Naturally, an end node capable of operating in fullduplex can handle data much faster than an end node that can only operate in half-duplex mode.
AT-GS950/48 Gigabit Ethernet WebSmart Switch Installation Guide data link, which stops the end node. When the switch is ready to receive data again, the switch stops forcing collisions. This is referred to as back pressure. A port operating at 100 Mbps and full-duplex mode uses PAUSE frames, as specified in the IEEE 802.3x standard, to stop the transmission of data from an end node. Whenever the switch wants an end node to stop transmitting data, it issues this frame.

Appendix B Cleaning Fiber Optic Connectors The fiber optic connector consists of a fiber optic plug and its adapter. The end of the fiber optic cable is held in the core of the ferrule in the plug. Light signals are transmitted through the core of the fiber. Even minor smudges or dirt on the end face of the fiber, completely invisible to the naked eye, can disrupt light transmission and lead to failure of the component or of the entire system.
Appendix B: Cleaning Fiber Optic Connectors Using a Cartridge-Type Cleaner PUSH OPEN Di re c A PEng TAWipi tion Fiber optic cartridge cleaners are available from many vendors and are typically called “cartridge cleaners,” as shown in Figure 21. Figure 21. Cartridge Cleaner Note Do not use compressed air or aerosol air to clean a fiber optic connector. To clean a fiber optic connector using a cartridge cleaner, perform the following procedure. 3.
AT-LX3800U Multi-Service Transport System Installation and Maintenance Guide Note Rub the ferrule tip on the cleaning surface in one direction only. 5. When you reach the end of the cleaning surface, pick up the ferrule tip, rotate and place it at the top and rub downwards at least 2 times. Caution Failing to pick up the ferrule tip when you reach the bottom of the cleaning surface can result in static electricity that can damage the fiber optic cable. 6. If desired, repeat steps 3 and 4. 7.
Appendix B: Cleaning Fiber Optic Connectors Using a Swab Specially treated swabs (stick cleaners) are available for cleaning inside connector adapters or hard-to-reach ferrule tips. These swabs, often referred to as “lint free” or “alcohol free” swabs, are available from many vendors, as shown in Figure 23. Stick cleaners are available in both 2.5 mm and 1.25 mm sizes for use on SC and MU connectors respectively. Note NEVER use a household cotton swab and/or alcohol to clean a fiber optic connector.
AT-LX3800U Multi-Service Transport System Installation and Maintenance Guide 3. If a fiber inspection scope is available, use the scope to inspect the connector to make sure that it is clean and to check for scratches, pits, or other problems that may affect performance. Note Always keep a dust cap on a fiber optic cable when it is not in use. Note Do not touch the end face of the ferrule in the connector. Warning: Do not stare into the laser beam.
