GarrettCom, Inc. Stackable Hub DS8016

Features • Provides sixteen RJ-45 ports per hub, each port speed-sensing for 100Mb or 10Mb • Combines both 100Mb and 10Mb port speeds with stackability for expansion, for flexibility in rack installations • Durable metal enclosure, stacking cable, rack-mount brackets, rubber feet for tabletop mounting, internal auto-ranging power supply • Available options include -48VDC power, dual source, “reverse” rack mount, ETSI and 23” Telco brackets • NEBS compliant -48VDC models Description Magnum DS8016 Stackable Hubs provide the flexibility of 100Mb and 10Mb Ethernet ports in one hub along with the expandability of stacking. Medium-sized networks that need to mix ports at 100Mb performance for high bandwidth applications with economical 10Mb ports for other nodes can benefit from the domain-switched dualspeed 10/100 Magnum DS8016s. Dual-speed network chip technology enables the Magnum DS8016 Dual-Speed hubs to identify and accept either 100Mb or 10Mb signals on a per-port basis. Each RJ-45 port is independently auto-sensing for speed, adapting at the time of LINK-enable to match the speed of the connected device. This capability provides the ultimate in flexibility for small-to-medium sized mixed-speed networks that are gradually transitioning from 10Mb Ethernet to 100Mb Fast Ethernet speed. The Magnum DS8016 Dual-Speed units support two shared traffic domains, one at 100Mb and one at 10Mb. Each port is connected into the appropriate 100Mb or 10Mb domain, depending on its speed as sensed. Any combination of 100Mb or 10Mb ports may be in use. The B- models of the Magnum DS8016 Domain-Switched hubs include an internal switch or bridge to interconnect the two shared traffic domains, enabling all users on a DS8016 stack, whether 100Mb or 10Mb, to talk to each other. This self-learning switch filters and selectively forwards packets between the two traffic domains, unifying them. Each domain’s performance is maintained at its peak potential, unaffected by local traffic on the other domain. Only one DS8016 with an internal switch unit is necessary to support the entire stack. The Magnum DS8016 is also available in “Reverse” models with front-mounted LEDs, rear ports and power connection. The Magnum DS8016 stackable hub and other Magnum products are made in the USA and are backed by a three-year warranty.
