to cascade two DS8016 hubs or stacks together, the auto-sensing feature will cause the
connecting link to operate at 100Mb speed.
2.6 Features and Benefits
„ Supports 10 or 100Mb network connections on each of sixteen RJ-45 ports
Magnum DS8016 Dual-Speed 10 / 100 hubs combine two logical hubs . . . one at
10Mb and one at 100Mb . . . in one physical box supporting two traffic domains. Each
port can operate at either 10 or 100Mb, independently of the other ports.
„ Auto-sensing for speed, 10 or 100Mb on each port
All ports support 10/100 auto-negotiation for speed, operating separately on each port.
Any mix of 10Mb and 100Mb users can be connected to the ports. Speed-sensing
occurs at LINK-enable independently on each port. Individual ports can change to
100Mb or 10Mb speed at any time (LINK off, then on again), adapting automatically
to any changes in the connected device’s speed. Speed-sensing complies with IEEE
802.3u, providing interoperability with other products.
„ An internal switch connects the 10 and 100Mb domains on Model DS8016-B
Model DS8016-BAND DS8016-R has an internal switch for filtering / forwarding
traffic between the 10 and 100Mb domains, allowing all connected devices to
communicate to each other. High performance switching provides full bandwidth in
each domain, unaffected by local traffic on the other domain. One DS8016-B per stack
supports switching for all ports.
„ Stackable for flexible expansion
Magnum DS8016s can be stacked up to three units high for 48 ports, each 10 / 100
dual speed. As additional units are added in a stack, 10 and 100Mb traffic domains are
expanded automatically to support the new ports at either 10 or 100Mb speed.
„ Installation is “Plug and Play”, Operation is Transparent to Software
The Magnum DS8016-B operates as a hardware switch, only forwarding those packets
from each domain that are needed on the other domain. Internal address tables are
self-learning, enabling users to change port connections or 10 / 100 domains without
affecting operations. The switch in the DS8016-B will not affect any standard
software applications or SNMP network management platforms.
