    GARRETT GARRETT 10M LINK/ACT Figure 2.2.1 : Magnum DS80 is functionally both a 10 Mbps and a 100Mbps hub in one The Magnum DS80 includes an internal bridge or switch I.C. (Integrated Circuit) which interconnects the 10 Mbps and the 100Mbps traffic domains. This enables all users on a DS80 hub, whether 100Mbps or 10Mbps, to talk to each other.

  • Page 11: Magnum Ds80 Chassis

    2.2.1 Magnum DS80 Chassis The Magnum DS80 chassis houses one main PC board with a bridge IC on board, and an external power supply unit. The front side of the chassis has eight RJ-45 twisted-pair ports and one cascading (Up-link or Crossover) Port, # 8X, on the right.
  • Page 12 Magnum DS80 Dual-Speed Personal Hub Installation and User Guide (11/98) course, the hubs’ auto-negotiation technique is only for 10/100 speed, and does not provide for any full-duplex operation. The per-port 10/100Mbps Link/Activity LEDs on the front panel indicate the result of auto-sensed speed detection, and the resulting connectivity to either a 10 Mbps or 100Mbps device.

  • Page 14: Features And Benefits

    Features and Benefits Supports 10 or 100Mbps network connections on each RJ-45 port Magnum DS80 Dual-Speed 10/100 hubs combine two logical hubs -- one at 10 Mbps and one at 100Mbps -- in one physical box supporting two traffic domains. Each port can operate at either 10 or 100Mbps, independently of the other ports.

  • Page 15: Applications

    Applications Example 1 : A Magnum DS80 Personal Hub serves a small office with mixed speed requirements. Some users operate at 100Mbps, and some users and utility devices (such as print servers) run at 10Mbps. All share the same hub, and communicate to each other via the bridge chip inside.

  • Page 16: Installation

    Locate an AC receptacle that is within six feet (2 meters) of the intended Magnum DS80 site. The rugged metal case of the Magnum DS80 will normally protect it from accidental damage in a lab or workplace setting. Maintain an open view of the front to visually monitor the status LEDs.

    Air coming out of the rear of unit DC 5V Magnum DS80 based on smart cooling design is a fan cooled unit. DS80 is designed very carefully, so that the unit get cooled easily while running. The air exhale out smoothly from the rear side of the unit.
  • Page 20 Table 4.1: DS80 Dual-Speed Hub Functionality Address Learning (Address Table Maintenance) The Magnum DS80 bridge chip is a state machine design which has a total address table capacity of 1.8K addresses. With a large address table, a Magnum DS80 can serve the needs of a medium-sized to large network. Table 4.1 shows what filter / forward action the Magnum DS80 will take in each packet-processing situation, and when a new node address will be added to the internal Address Table.

  • Page 21: Auto-Negotiation And Speed-Sensing

    By selectively forwarding packets from each domain to the other domain based on its switching (bridging) logic, the Magnum DS80 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 over there.
