  • Page 9: Introduction

    Product Description - Magnum 500-Series Switching Hubs The Magnum 500-Series Switching Hubs provide 8-port switching services to enhance the performance of 10Mb Ethernet networks by segmenting the network traffic. They may be used with existing Cat 3 cabling and shared 10b Ethernet hubs. On models 528 and 528F, there are two Fast Ethernet switched ports additionally that provide 100Mb switching services for high speed network connections.

  • Page 10: Magnum 500-Series Chassis

    Magnum 500-Series Switching Hubs Designed for use in departments with multiple workgroups, in remote offices and in network traffic centers, the Magnum 500-Series switches are easy to install and use. Addresses of attached nodes are automatically learned and maintained, adapting the switching services to network changes and expansions.

  • Page 11: 100Mb Ports, Full- Or Half-Duplex And Auto-Negotiation Modes

    Figure 2.2.2: two@100Mb copper ports (528 model), 1@100Mb copper and 1@100Mb fiber ports (528F models), and 8@10Mb ports All Magnum 500-Series Switching Hubs provide eight 10Mb switched ports. All 10Mb switched ports are independently auto-negotiating for selecting to operate in full-duplex mode, and will independently default to half-duplex mode when the 10Mb device at the other end is half-duplex or is not an auto-negotiating device.

  • Page 12: Mb Fiber Port, Stor Sc Type(Single Mode Or Multi Mode)

    On the Magnum 528 and 528F models, the user may select full- or half-duplex mode per-port with a manual switch for flexibility to adapt to any type of Fast Ethernet devices. The Full/Half-duplex manual switches are located on the front panel under the corresponding Fast Ethernet ports for convenient access.
  • Page 13 The latency (the time the frame spends in the switch before it is sent along or forwarded to its destination) of the 500-Series switches varies with the port-speed types, and the length of the frame is a variable here as it is with all store-and-forward switches.

  • Page 14: Features And Benefits

    ! ! ! ! Small package for office networks, "Universal" Power Supply The compact package of the Magnum 500-Series switches allow them to be used in office networks where a large rack-mount unit would be undesirable. An internal auto-ranging AC power supply allows any Magnum 500-Series Switching Hub to be used throughout the world.

  • Page 15: Applications

    Magnum 500-Series Switching Hubs Applications Magnum 500-Series Switching Hubs offer a great deal of performance and flexibility, and are easily used in a variety of ways including client/server applications, departmental networks performance upgrades and collapsed backbone applications. Example 1 : Magnum 508 In a typical 10Mb network performance upgrade, multiple cascaded 10Mb hubs connect all networked devices using one 10Mb traffic domain.
  • Page 16 Fast Ethernet ports provide 100Mb F/H each, and have full-speed switched access to each other as well as to each of the 10Mb ports. 100Mb Server, PCs Figure 2.4c: Using a Magnum 528 Switch, 100Mb servers and users are added GARRETT Installation and User Guide (08/98)
  • Page 17 Magnum 500-Series Switching Hubs Example 3 : Magnum 528 In another situation similar to Example 2 above, the network may need to be linked to a Fast Ethernet backbone. This application is handled by the Magnum 528 using one 100Mb switched port for local high speed servers and users, while using the other 100Mb switched port for a link upstream.
  • Page 18 Magnum 500-Series Switching Hubs Example 4 : Magnum 528F In another situation similar to Example 3 above, the network may need to be linked with fiber cabling to a Fast Ethernet backbone. This application is handled by the Magnum 528F, using one 100Mb switched copper port for local high speed servers and users, while using the fiber 100Mb switched port for the fiber backbone connection.

  • Page 19: Table-Top Or Shelf Mounting

    3.1.1 Table-Top or Shelf Mounting The Magnum 500-Series switch can be easily mounted on a table-top or any suitable horizontal surface, and has four rubber feet to provide stability without scratching finished surfaces. When stacked, the rubber feet also provide separation between units for the exhaust of the rear cooling fan.

  • Page 20: Wall (Or Vertical) Mounting

    Optional E-Stand The optional E-Stand provides a vertical mounting option for the Magnum 500-Series Hubs. When horizontal placement is not possible or desirable (such as on the floor in carpeted areas), the E-Stand offers a unique space management option. Simply align the rectangular cut-out on the E-Stand with the air vent on either side of the Magnum 500 unit.
  • Page 21 Figure 3.1.3 : Magnum 528 mounted on E-stand Powering the Magnum 500-Series Switch Magnum 500-Series Switching Hubs incorporate an internal universal power supply, and have a recessed male IEC connector for the AC power cord at the right-rear. A six-foot 115 VAC 60 Hz standard power cord is supplied with each unit shipped within the United States and Canada.

  • Page 22: Connecting Ethernet Media

    Magnum 500-Series Switching Hubs Connecting Ethernet Media The Magnum 500-Series Switching Hubs can be connected to the following media types: 100BASE-TX and 10BASE-T. (Magnum 508’s only have 10BASE-T ports). CAT 5 cables should be used when making 100BASE-TX connections. When the ports are used as 10BASE-T ports, CAT 3 may alternatively be used.

    Magnum 500-Series Switching Hubs 3.3.2 Connecting Fiber Optic 100BASE-FX, Type ST and SC 100 Mb P WR F /H 100BASE-TX connections (Magnum 528F only) The following procedure applies to 100BASE-FX applications using the Magnum 528F Switching Hub with ST-type (twist-lock) and SC-type (snap-in) fiber connectors.

Each Magnum 500-Series port is a separate traffic domain, and all ports operate to maximize bandwidth utilization and network performance. All ports can talk to all other ports in a Magnum 500, but local traffic on a port will not consume any of the bandwidth on any other port.

  • Page 26: Status Leds

    Figure 4.3 : Up-link and F/H manual switches on front panel The unit has a manual Up-link switch, located on the front panel next to 10Mb Port # 8 which it controls. It enables the port’s cable to either connect to a user station node (= position) or to be cascaded (X position) to a another 10Mb repeater or switching hub in the network.

  • Page 27: Auto-Negotiation Option For Copper Fast Ethernet Ports

    If the Magnum 528’s Fast Ethernet copper ports are internally set for auto-negotiation (AUTO LED is ON), then the F/H switch selection has no effect. The adjacent F/H LED will indicate the full- or half-duplex operating status of the port as determined by the internal auto-negotiation logic.

  • Page 28: Auto-Negotiation For 10Mb Ports, Half- Or Full-Duplex Mode

    Magnum 500-Series Switching Hubs The auto-negotiation logic will attempt to operate in descending order and will normally arrive at the highest order mode that both devices can support at that time. (Since auto- negotiation is potentially an externally-controlled process, the original “highest order mode”...

  • Page 29: Collision-Based Flow Control

    The purpose of flow-control is to reduce the risk of data loss if a long burst of activity causes the switch to backlog frames until its memory is fill up. This is most likely to occur when data is moving from a 100Mb port to a 10Mb port, and the speed difference makes the 10Mb port unable to keep up.

  • Page 30: Troubleshooting

    Make sure that an AC power cord is properly attached to each Magnum 500-Series unit. Be certain that each AC power cord is plugged into a functioning electrical outlet. Use the PWR LEDs to verify each unit is receiving power.

  • Page 32: Shipping And Packaging Information

    Magnum 500-Series Switching Hubs Shipping and Packaging Information Should you need to ship the unit back to Garrett Communications, please follow these instructions: 1. Package the unit carefully. It is recommended that you use the original container if available. Units should be wrapped in a "bubble-wrap" plastic sheet or bag for shipping protection.
  • Page 33 The operational range for the 48 VDC power supply is 36 - 72 VDC. Each unit is normally convection-cooled for silent operation. The functionality of the Magnum 500-series with 48VDC power options is identical to the standard 508, 528 and 528F models.
  • Page 34 48 VDC power terminal block on the Magnum 500-series switching hub. The 48 VDC terminal block on the Magnum 500-series is located on the rear of the unit and is equipped with three (3) screw-down lead posts. The leads are identified as negative (-), positive (+), and chassis ground (GND).
