    When networks are based on repeater (hub) technology, the distance between end stations is limited by a maximum hop count. However, a switch turns the hop count back to zero. So subdividing the network into smaller and more manageable segments, and linking them to the larger network by means of a switch, removes this limitation.
  • Page 26: Application Examples

    Network Planning Application Examples The MIL-SM4804G switch is not only designed to segment your network, but also to provide a wide range of options in setting up network connections. Some typical applications are described below. Collapsed Backbone The MIL-SM4804G is an excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit Ethernet installations where significant growth is expected in the near future.
  • Page 27: Network Aggregation Plan

    You can stack up to four MIL-SM4804G switch units together, forming a single “virtual” switch containing up to 200 ports. The whole stack can be managed through the Master unit using a single IP address.

  • Page 30: Application Notes

    Application Notes Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode. Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem.

    Slide the SFP transceiver into the slot until it clicks into place. Note: SFP transceivers are hot-swappable. The switch does not need to be powered off before installing or removing a transceiver. However, always first disconnect the network cable before removing a transceiver.
  • Page 37: Figure 3-6 Connecting Switches In A Ring-Topology Stack

    You can form a stack containing up to four MIL-SM4804G units. To connect switches in a stack, perform the following steps: Enable the stacking ports on each unit (i.e., the Stack button pushed out) Note: Pressing the Stack button during normal operation will cause the system to reboot.
  • Page 38: Connecting To A Power Source

    Select the Master unit in the stack by pressing in the Master button on only one of the switches. Only one switch in the stack can operate as the Master, all other units operate in slave mode. If more than one switch in the stack is selected as Master, or if no switches are selected, the stack will not function.

    Connecting to the Console Port The DB-9 serial port on the switch’s back panel is used to connect to the switch for out-of-band console configuration. The command-line-driven configuration program can be accessed from a terminal or a PC running a terminal emulation program. The pin assignments used to connect to the serial port are provided in the following table.

    In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3, and 6 at the other end of the cable. When using any RJ-45 port on this switch, you can use either straight-through or crossover cable.
  • Page 52: Straight-Through Wiring

    If the twisted-pair cable is to join two ports and only one of the ports has an internal crossover (MDI-X), the two pairs of wires must be straight-through. (When auto-negotiation is enabled for any RJ-45 port on this switch, you can use either straight-through or crossover cable to connect to any device type.) You must connect all four wire pairs as shown in the following diagram to support Gigabit Ethernet.
