Magnum 3024 Hub - 24 RJ-45 Ports, One PM bonus port slot

The Magnum 3024 Hub provides 24 RJ-45 ports on the front of the unit plus a

Bonus Port slot on the rear which may be configured with any Magnum Port Module

(PM). User-segment wiring connections are made on the front of the unit, and status-

indicator LEDs are located immediately above each of the 24 ports.

Figure 2.3a, Magnum 3024 Hub, Front View

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.)

Stacking 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.
