GarrettCom Magnum 20X manual Repeater Functionality

This section describes the functionality and operation of the Magnum 200X Two- Port repeaters.

4.1Repeater Functionality

The Magnum 200X units operate as mixed-media or homogeneous Ethernet repeaters. Both types are compliant with IEEE 802.3 specifications and supports all IEEE defined media, including 10BASE-T, 10BASE-FL, FOIRL, 10BASE2, and 10BASE5. The following describes the basic functionality of the Magnum 200X Two-Port Repeaters.

1.Repeater Functions: Each RPM port operates in conjunction with the controller functions of the Magnum 200X base unit, functioning together as a fully compliant Ethernet repeater. Each 200X unit counts as a single repeater.

2.Collisions: When a collision is detected at a port other than the original receiving port, it generates a jam pattern to the other ports. When a collision signal is detected at a receiving port, it generates a jam pattern to the other port. The sequence of jam signals depends on the sequence and location of collisions.

3.Partitioning and Re-connection:A Magnum 200X will automatically disconnect (partition) any segment (port) when 64 consecutive collisions occur or after 6.5 ms of continuous transmissions. Network integrity is checked every 800 ms and segment (port) reconnection occurs after a 512-bit packet is transmitted without error.

4.Link Status: The Magnum 200X RPMs indicate link integrity for fiber optic and twisted pair segments. Broken cables or a loss of power at any point in twisted pair and fiber segments will turn off the LINK LED indicator on the associated RPM.
