  • Page 13: Chapter 2 Installation Requirements/Specifications

    REQUIREMENTS/SPECIFICATIONS This chapter describes network guidelines, power requirements, and operating specifications for the MRXI. Be sure that you read this chapter before you install the MRXI. Your network must meet the requirements and conditions specified in this chapter to obtain satisfactory performance from this equipment.

  • Page 14: Network Guidelines

    INSTALLATION REQUIREMENTS/SPECIFICATIONS NETWORK GUIDELINES Take care in planning and preparing the connections and the cables for your network. The quality of the connections, the length of the cables, and the location of the MRXI are critical factors in determining the reliability of your network.

  • Page 15: Multi Mode Fiber Optic Network Requirements

    INSTALLATION REQUIREMENTS/SPECIFICATIONS • Jitter - Intersymbol interference and reflections can cause jitter in the bit cell timing, resulting in data errors. A 10BASE-T link must not generate more than 5.0 nsec. of jitter. If your cable meets the impedance requirements for a 10BASE-T link, jitter should not be a concern.

  • Page 16: Single Mode Fiber Optic Network Requirements

    INSTALLATION REQUIREMENTS/SPECIFICATIONS • Attenuation - The fiber optic cable must be tested with a fiber optic attenuation test set that is adjusted for an 850 nm wavelength. This test verifies that the signal loss in a cable is within an acceptable level: 13.0 dB or less for 50/125 fiber cable segment.

  • Page 17: Thin-Net Network Requirements

    INSTALLATION REQUIREMENTS/SPECIFICATIONS • Fiber optic budget is the combination of the optical loss due to the fiber optic cable, in-line splices, and fiber optic connectors (the loss for each splice and connector is typically 1 dB or less). • Propagation delay is the amount of time it takes a packet to travel from the sending device to the receiving device.

  • Page 18: Transceiver Requirements

    INSTALLATION REQUIREMENTS/SPECIFICATIONS 2.3.5 Transceiver Requirements When you connect an external network segment, via a transceiver, to the MRXI with an EPIM-A, the following requirements must be met: • The transceiver or Ethernet Device to which the module will be connected must meet IEEE 802.3 standards, and/or Ethernet Version 1.0 or Version 2.0 standards.
