Magnum DS8016 Dual-Speed Stackable Hubs 2.2 Installation and User Guide (07/06) Product Description - General Magnum DS8016 Dual-Speed hubs have sixteen RJ-45 ports, each 10/100Mb auto- sensing *. Each port can independently identify (via IEEE 802.3u auto-sensing) and accept either 100Mb or 10Mb Ethernet signals, adapting to match the best speed of the connected device. There are two internal traffic domains in Magnum DS8016 hubs, one for the 100Mb traffic and one for the 10Mb traffic.
Magnum DS8016 Dual-Speed Stackable Hubs Installation and User Guide (07/06) Another DS8016 model, the DS8016-A, has no switch module inside, but is dual speed and is normally used stacked with a DS8016-B for dual-speed port expansion.
Magnum DS8016 Dual-Speed Stackable Hubs Installation and User Guide (07/06) LEDs to indicate operating status are on the front side. There are power (PWR) and bridge-inside (BR) indicators for the unit. There are collision (COL) indicators for each of the 10Mb and 100Mb domains, for visual indication of the operating status of each domain.
Magnum DS8016 Dual-Speed Stackable Hubs Installation and User Guide (07/06) 2.2.3: Magnum DS8016-E model, 100Mbps -only The Model DS8016-E is like the DS8016-A except that it’s speed is internally fixed at 100Mbps on all ports. It is not dual-speed. It has no bridge inside. It is used for 100Mbps-only applications, and it can operate stand-alone or stacked with the other DS8016B and DS8016-A models. Special orders of this model can be built with some ports fixed at 10Mb.
Magnum DS8016 Dual-Speed Stackable Hubs 2.3 Installation and User Guide (07/06) Stacking Magnum DS8016s Up to three Magnum DS8016s can be stacked to operate as one 10/100 dual-speed repeater with up to 48 dual-speed ports. Normally, one Magnum DS8016-B hub per stack is needed to provide a switched interconnection between the two separate 100Mb and 10Mb traffic domains in the stack. Additional stacked units are normally Model DS8016-A or -E “add-on” units, which cost less.

Magnum DS8016 Dual-Speed Stackable Hubs 2.7 Installation and User Guide (07/06) Applications Example 1 : A Magnum DS8016-B serves a small office with mixed speed requirements. Some users operate at 100Mb, and some users and utility devices (such as print servers) run at 10Mb. All share the same hub, and talk to each other via the bridge module inside. Any node can change speed at any time without affecting network operation or impacting other users.
Magnum DS8016 Dual-Speed Stackable Hubs Installation and User Guide (07/06) Example 3 : For additional expansion, DS8016s can be expanded by stacking DS8016-A “addon” units. The additional stacked ports are all auto-sensing dual-speed domain-switched, and can be used at either 10Mb or 100Mb on a per-port basis. The stacking cables connect the DS8016 units and carry the signals for both the 100Mb and the 10Mb domains.
Magnum DS8016 Dual-Speed Stackable Hubs Installation and User Guide (07/06) Example 4: A Magnum DS8016-R serves a good solution for the user, who expect a high-availability, neat networking connection with clear visible display of LEDs port.

Magnum DS8016 Dual-Speed Stackable Hubs 3.0 Installation and User Guide (07/06) Magnum DS8016 Installation Before installing the equipment, it is necessary to take the following precautions: 1.) If the equipment is mounted in an enclosed or multiple rack assembly, the environmental temperature around the equipment must be less than or equal to 500C. 2.) If the equipment is mounted in an enclosed or multiple rack assembly, adequate air flow must be maintained for proper and safe operation. 3.
Magnum DS8016 Dual-Speed Stackable Hubs 3.1.2 Installation and User Guide (07/06) Rack-Mounting Installation of a Magnum DS8016 Stackable Hub in a 19” rack is a simple procedure. The units are 1U (1.75”) high, including the rubber feet underneath. When properly installed, the front-mounted LED status indicators should be in plain view and easy to read. Rack-mount installation requires special rack-mounted brackets and screws (included with each DS8016).
Magnum DS8016 Dual-Speed Stackable Hubs Installation and User Guide (07/06) the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer. B) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.

Magnum DS8016 Dual-Speed Stackable Hubs Installation and User Guide (07/06) industry standards normally permit, and is different from what competitive 100Mbps Class II hub products normally allow. This additional cascading level and cable length is due to the relatively shorter bit time (80 BT actually measured, for front-port-to-port) delay of the Magnum DS8016 vs. the industry standard delay of 92 BT for Class II repeaters.
Magnum DS8016 Dual-Speed Stackable Hubs Installation and User Guide (07/06) VAC 60Hz power cord is supplied with each unit shipped within the United States and Canada. Each Magnum DS8016’s auto-ranging power supply supports installation environments where the AC voltage is from 90 to 260 volts with an input frequency between 47 and 63 Hz, and consumes a maximum of 27 watts.
Magnum DS8016 Dual-Speed Stackable Hubs Installation and User Guide (07/06) 10Mb Domain : 10Mbps packets are forwarded when the destination addresse is NOT in the 10Mb domain address table. 100Mbps Domain100Mbps : packets are forwarded when the destination address is NOT in the 100Mb domain address table. 10Mbps Domain :10Mbps packets are filtered when the destination address is in the 10Mbps domain address table.
Magnum DS8016 Dual-Speed Stackable Hubs Installation and User Guide (07/06) By selectively forwarding packets from each domain to the other domain based on its switching (bridging) logic, the domain-switched Magnum DS8016-B increases the available bandwidth for the users on both sides of the network. As shown in Figure 4.1, it keeps the local traffic on each side contained, preventing unnecessary packets and bad packets from traveling to the other domain and using up bandwidth needlessly there.
Magnum DS8016 Dual-Speed Stackable Hubs 4.2 Installation and User Guide (07/06) Auto-negotiation and speed-sensing All sixteen RJ-45 ports independently support auto-negotiation for shared 10BASE-T and 100BASE-TX modes. When the ‘100’ LED is flashing, it means that the corresponding port is sending out auto-negotiation pulses on that port. When a LINK connection is made, the other device should respond and both sides should agree to the speed being signaled.
