Magnum 8000X Mixed-Media Fiber Hubs Installation and User Guide (05/ 02) With this large address table, SPM port modules can serve the needs of medium-sized to large networks. The address tables are flushed periodically to update the network status and to purge any inactive stations from the tables. See the figure and table that follows: Segment 1 Segment 2 (Bonus Port) (Inside of Hub) Segment 2’s packets are filtered when the destination addresses are in its address table.
Magnum 8000X Mixed-Media Fiber Hubs Installation and User Guide (05/ 02) no software configuring and is transparent to system and application software, including network management software. 2.5.1 Magnum SPM-FDST The significant feature of the SPM-FDST is that the fiber bonus port operates in full-duplex mode, sending packets on one fiber filament while simultaneously and independently FULL DU PLEX receiving packets on the other.
Magnum 8000X Mixed-Media Fiber Hubs Installation and User Guide (05/ 02) buffer is 1Mbps to maintain high network performance. The MAC address memory is 8KB, suitable for medium to large networks. In summary, the Magnum SPM-FDST is a multi-mode fiber optic switching port module. It has 100Mb ST-type connectors. There are two LEDs, LINK and RX, to allow monitoring of LINK and packet reception (Activity) status of the SPM.
Magnum 8000X Mixed-Media Fiber Hubs Installation and User Guide (05/ 02) SPM-FDSSC’s can be used together on each end of a fiber segment to get the maximum distance of 15km of single-mode fiber optic cable in a Fast Ethernet network. For an SPM-FDSSC used to connect into a separate collision domain, the cable distances and hop-counts allowable would have to be calculated taking into account all the devices’ Path Delay Values (PDVs) that are part of that domain.
Magnum 8000X Mixed-Media Fiber Hubs 2.6 Installation and User Guide (05/ 02) 10 /100 Speed Auto-sensing (8000X front copper ports only) Twisted pair copper ports (PM-RJ45 or PM-RJ45U only) support auto- sensing for speed, independent of the other ports. Speed-sensing is performed by the Magnum 8000X’s electronics in accordance with the standards of the IEEE 802.3u auto-negotiation standard.
Magnum 8000X Mixed-Media Fiber Hubs Installation and User Guide (05/ 02) 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 “addon” units or two DS8016-A hub units can be stacked to operate as one 10/100 DualSpeed repeater with up to 48 dual-speed ports, with any mix of fiber and copper port types.
Magnum 8000X Mixed-Media Fiber Hubs Installation and User Guide (05/ 02) The bridge operates in the store-and-forward mode, which filters out bad packets and maintains optimum performance in both domains. Packet forwarding delay is only 5µs (plus packet time), much less than traditional store-and-forward bridge products, enabling the 8000Xs to maintain high network performance. The bridge has 8K node address capacity, suitable for use in large networks.

Installation and User Guide (05/ 02) Features and Benefits Supports 10 or 100Mb network connections on each of sixteen ports Magnum 8000X Dual-Speed Fiber 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.
Magnum 8000X Mixed-Media Fiber Hubs 2.10 Installation and User Guide (05/ 02) Applications The 8000X Port Modules are factory and field configurable. This (and the stacking feature) provides for easy expansion of the network, and it provides flexibility to adapt to new fiber port connector types as technology changes. The flexibility of the Magnum 8000X makes it the choice for applications that require a flexible and adaptable 10/100 hub. See also Section 1.
Magnum 8000X Mixed-Media Fiber Hubs Installation and User Guide (05/ 02) The Magnum 8000X Fiber Hubs support all of the fiber port types (including the latest models), adapting the fiber LAN to changing technology. The Dual- Speed feature provides for growth in performance to higher bandwidth 100Mbps speed, and the perport modularity plus stacking provide for port expansion.
Magnum 8000X Mixed-Media Fiber Hubs 3.0 Installation and User Guide (05/ 02) Magnum 8000X 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 8000X Mixed-Media Fiber Hubs Installation and User Guide (05/ 02) The various media types supported along with the corresponding IEEE 802.3 and 802.3u standards and connector types are as follows: IEEE Standard Fiber: 10BASE-FL Media Type mm1 Fiber 100BASE-FX small form factor sgl.m2 Fiber mm1 Fiber Max.

Magnum 8000X Mixed-Media Fiber Hubs Installation and User Guide (05/ 02) When connecting fiber media to SC connectors, simply snap on the two square male connectors into the SC female jacks of the PM until it clicks and secures. 3.5 Connecting Single-Mode Fiber Optic When using single-mode fiber cable, be sure to use single-mode fiber port connectors. Single-mode fiber cable has a smaller diameter than multi-mode fiber cable (9/125 microns for single-mode, 50/125 or 62.
Magnum 8000X Mixed-Media Fiber Hubs 4. Installation and User Guide (05/ 02) For Port #1, if the LINK LED is not illuminated, change to port 1X. If this does not help, ensure that the cable is connected properly and that the device on the other end is powered on and is not defective. 3.6.1 100Mbps Collision Domain Diameter, Cable Distances and PDV Calculations The 100Mbps Collision Domain Diameter is the length of the longest path between any two devices in a single collision domain.
Magnum 8000X Mixed-Media Fiber Hubs Installation and User Guide (05/ 02) To determine whether a prospective network topology adheres to the collision domain diameter specification, the following formula should be applied to the worst case path through the network. The worst case path is the path between the two Fast Ethernet devices (DTEs) which have the longest round-trip time.
Magnum 8000X Mixed-Media Fiber Hubs Installation and User Guide (05/ 02) The resulting value tells us that a Category 5 cable with a length of up to 25 meters may be used to cascade the Magnum 8000Xs. Note that this inter-repeater cable length may be increased by shortening the lengths of the 100m hub-to-user cable segments. It is also possible to cascade a group of up to nine Magnum 8000Xs (serving up to 56 users with full-length 100m cables to each) by using short inter-repeater cable segments.
