    Chapter 5 Troubleshooting the Installation Identifying Startup Problems If you encounter a problem in performing any of the above checks, you should contact a customer service representative. Identifying Startup Problems LEDs indicate all system states in the startup sequence. By checking the LEDs, you can determine when and where the system failed in the startup sequence.

  • Page 94: Troubleshooting The Power Supply

    If the LED is amber or off, repeat the previous procedure to troubleshoot the second power supply. If the power supply is a Cisco RPS 675 and the LED is amber, the RPS may be in Note standby mode. Press the Standby/Active button on the RPS to put it in active mode and the LED should then turn to green.

    A P P E N D I X Differential Mode Delay When an unconditioned laser source designed for operation on a single-mode fiber (SMF) cable is directly coupled to a multimode fiber (MMF) cable, differential mode delay (DMD) might occur. DMD can degrade the modal bandwidth of the fiber-optic cable.
  • Page 108 Appendix C Differential Mode Delay DMD does not occur in all deployed fibers; rather, it occurs with certain combinations of worst-case fibers and worst-case transceivers. Gigabit Ethernet is the first technology to experience this problem because of its very high baud rate and its long MMF cable lengths.
  • Page 109 Appendix C Differential Mode Delay modes. This is in contrast to an unconditioned launch, which, in the worst case, might concentrate all of its light in the center of the fiber-optic cable, exciting only two or more modes equally. A significant variation in the amount of DMD is produced from one MMF cable to the next.
