  • Page 15: Chapter 1: Introduction

    Chapter 1: Introduction Overview The MIL-SM24004TG Gigabit Ethernet Switch is an intelligent switch with 24 10/100/1000BASE-T ports, four of which are combination ports that are shared with four SFP transceiver slots. There is also an SNMP-based management agent embedded on the main board. This agent supports both in-band and out-of-band access for managing the switch.

  • Page 16: Switch Architecture

    Description of Hardware 10/100/1000BASE-T Ports The MIL-SM24004TG contains 24 RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or full duplex, or at 1000 Mbps, full duplex. Because all ports on this switch support automatic MDI/MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs.

  • Page 17: Status Leds

    Status LEDs The LEDs, which are located on the front panel for easy viewing, are shown below and described in the following table. SFP Port Enabled Condition RJ-45 Ports Link/Act On/Flashing Yellow The port has a valid 10 or 100 Mbps link. Flashing indicates On/Flashing Green The port has a valid 1000 Mbps link.

  • Page 18: Optional Redundant Power Unit

    Optional Redundant Power Unit The switch supports an optional Redundant Power Unit (RPU) that can supply power to the switch in the event of failure of the internal power supply. Power Supply Receptacles There are two power receptacles on the rear panel of the switch. The standard power receptacle is for the AC power cord.

    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 22: Application Examples

    Gigabit Ethernet ports built into the front panel or a Gigabit Ethernet port on a plug-in SFP transceiver. In the figure below, the MIL-SM24004TG is operating as a collapsed backbone for a small LAN. It is providing dedicated 100 Mbps full-duplex connections to workstations and 1000 Mbps full-duplex connections to power users and servers.

  • Page 23: Network Aggregation Plan

    Network Aggregation Plan With 24 parallel bridging ports (i.e., 24 distinct collision domains), the MIL-SM24004TG can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 10/100/1000BASE-T ports on the switch are providing 100 Mbps connectivity for up to 24 segments through layer 2 switches.

  • Page 24: Remote Connection With Fiber Cable

    1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a 1000BASE-LX (SMF) link up to 5 km, and a 1000BASE-LH link up to 70 km. This allows a Gigabit Ethernet Switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.

  • Page 26: 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.

    Set the device on a flat surface near an AC power source, making sure there are at least two inches of space on all sides for proper air flow. If installing a single switch only, go to “Connecting to a Power Source” at the end of this chapter.
  • Page 32 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 35: Chapter 4: Making Network Connections

    Chapter 4: Making Network Connections Connecting Network Devices The MIL-SM24004TG is designed to interconnect multiple segments (or collision domains). It can be connected to network cards in PCs and servers, as well as to hubs, switches or routers. It may also be connected to devices using optional SFP transceivers.

  • Page 36: Network Wiring Connections

    Making Network Connections If the device is a PC card and the switch is in the wiring closet, attach the other end of the cable segment to a modular wall outlet that is connected to the wiring closet. (See “Network Wiring Connections” on page 4-2.) Otherwise, attach the other end to an available port on the switch.

  • Page 37: Fiber Optic Sfp Devices

    Connect one end of the cable to the LC port on the switch and the other end to the LC port on the other device. Since LC connectors are keyed, the cable can be attached in only one orientation.

    Making Network Connections As a connection is made, check the Link LED on the switch corresponding to the port to be sure that the connection is valid. The 1000BASE-SX, 1000BASE-LX and 1000BASE-LH fiber optic ports operate at 1 Gbps full duplex, with auto-negotiation of flow control.

    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 44: 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 connections.
