    “Station Power” LED indicates when power is applied to any of the Transceiver Ports. On the back of the AT-810SL are redundant LEDs indicating the application of “Station Power” for each Transceiver Port, and one redundant LED indicating “System Power.” Allied Telesyn STATION PORT TRANSCEIVER PORT CentreCOM...

  • Page 14: Chapter 2 Installation

    Chapter 2 Installation Requirements Attention Before installing AT-810SL Multiport Transceiver Fanouts, read the electrical safety and installation requirements starting on page i. Before installing the AT-810SL Multiport Transceiver Fanout, ensure that the following requirements are met: The network cabling is properly configured. Power connections are made at the back panel.

  • Page 15: Power

    Power The CentreCOM AT-810SL Multiport Transceiver Fanout is designed for desktop or rackmount installation with optional Rack Mount Kits AT-RKMT- 2 and AT-RKMT-3. AT-810SL requires a 100-240 VAC power source with a line frequency range from 50 Hz-60 Hz.

  • Page 16: Chapter 3 Operation

    Chapter 3 Operation Station Port Configuration The AT-810SL is designed to require a minimum of operator attention during routine operation. The station port configuration allows access, via an AUI cable and transceiver, to an Ethernet coaxial cable or fiber optic cable. This port is only used when the AT-810SL is set in Remote Mode.

  • Page 17: Led Status Indicators

    Operation LED Status Indicators The AT-810SL has many LEDs to aid in installation and troubleshooting should any problems occur. They also serve to verify correct transceiver operation at a glance. Below is a description of their location, grouping and functionality. Refer to Figure 3 for location of the System Power and Station Power.

  • Page 21: Chapter 4 Configuration

    Chapter 4 Configuration The CentreCOM Multiport Transceiver Fanout can be used to expand the number of allowable stations per transceiver in an Ethernet LAN in the following ways: Additional stations can be attached to an Ethernet coaxial cable segment which may have limited taps (MAUs) available. Where numerous stations are in close proximity, the number of transceivers connected to an Ethernet coaxial cable segment can be reduced.

    Appendix A IEEE 802.3 Quick Primer AUI Drop Cables AUI or Drop cables can be no longer than 50 meters (164 ft.) each. Attachments may be made only to the cable ends at the 15-pin D-shell connector. AUI Drop cables may have a maximum 257 ns propagation delay, as used for computing the worst case propagation delay of a cable system.

  • Page 24: Thin (10Base2) Ethernet

    IEEE 802.3 Quick Primer Thin (10BASE2) Ethernet When configuring thin coax segments, IEEE 802.3 specifications allow 30 or fewer MAU attachments per cable segment spaced at no less than 0.5 meters (1.64 ft.) between each attachment. The thin (10BASE2) cable length can not exceed 185 meters (606 ft.) per thin (10BASE2) cable segment.

  • Page 25: Appendix B Pin Assignments

    Appendix B Pin Assignments Notes Control In Shield (CI-S) is tied internally to the connector shell's Protective Ground (PG) and is capacitively coupled to ground through a .01 FD capacitor. Control In pair [(CI-A) and (CI-B)] are sometimes referred to as “Collision.” This signal pair carries messages from the MAU to the DTE in a Manchester encoded format to inform the DTE of the following: Message...
