The shielded RJ-45 port connectors on the front are electrically connected to the metal case of the unit, and are helpful in reducing electromagnetic noise radiation from the unit. (Note that the 10BASE-T wiring cable to the user may be unshielded or shielded, Category 3 or 4 or 5. The choice of wiring type is left to the installer based on preferences, standard practices and local or national wiring codes.)

2.3.1Stacking Magnum 3000s

The rear of the Magnum 3000 Stackable Hubs have an Inter-Repeater Bus

(IRB) connector on the right side. The IRB interconnects stacked units with a shielded ribbon cable, enabling all stacked Magnum 3000 units to operate as a single repeater.

There are two 34-pin IRB connectors on each unit: the bottom IRB connector which is used to daisy chain the IRB to the stacked Magnum 3000 unit below (unused on bottom unit in a Magnum 3000 stack); and the top IRB connector which is used to daisy chain the IRB to the stacked Magnum 3000 unit above (unused on top unit in a Magnum 3000 stack). The IRB connectors for an non-stacked unit are unused.
