..
Normally, one Magnum 8000X hub is needed to provide a switch between the 10 and
100Mbps domains.
With one base model Magnum 8000X, up to two additional 8000X-A “add-
on” units or two DS8016-A hub units can be stacked to operate as one 10/100 Dual-
Speed repeater with up to 48 dual-speed ports, with any mix of fiber and copper port
types.
When connecting mixed-media 8000X’s in a stack, use the stacking RS232
cable to connect the “OUT” stacking port from one 8000X unit to the “IN” stacking
port of the other. Push in the cable connectors until they seat in firmly. Also, leave
space along the left-side area for the exhaust of the internal cooling fan in each 8000X
unit.

2.8 Bridge Module between the 10 Mbps and 100Mbps Domains
Magnum 8000X’s contain a factory-installed bridge module to interconnect
the two traffic domains, filtering and selectively forwarding packets to allow only
necessary packets to cross between the domains. This enables all of the users and nodes
connected into either domain, whether 100Mbps or 10 Mbps , to communicate to each
other, and it keeps local traffic on one domain from consuming any of the bandwidth of
the other domain.
