4.0OPERATION

This chapter describes the function and operation of the Magnum 700X mixed-media concentrator and its various Port Modules (PMs).

4.1Repeater Functionality

The Magnum 700X operates as an Ethernet mini-concentrator or repeater to support the interconnection of multiple (two to seven) segments. The segments may be individually selected to be of any media type. The 700X is compliant with IEEE 802.3 specifications and supports all IEEE-defined Ethernet standard media, inclusive of 10BASE-T, 10BASE-FL, 10BASE2, FOIRL, 10BASE2, and 10BASE5.

The following describes the basic functionality of the Magnum 700X Mini- Concentrator.

1.Repeater Functions: Each RPM port operates in conjunction with the controller functions of the Magnum 700X base unit, functioning together as a fully compliant Ethernet repeater. The entire 700X 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 700X 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: Magnum 700X 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.

4.2BPM Local Bridge Functionality

When configured with BPMs, the network traffic on the Magnum 700X and its RPM-

attached devices is effectively isolated from the network segment connected through each of the BPMs. The local bridge functionality of the BPM bridge modules is described here.
