Maintaining MX150 Transceivers and Fiber-Optic Cables

Removing a Transceiver from an MX150

Before you begin removing a transceiver from the MX150, ensure that you have taken the necessary precautions for safe handling of lasers (see Laser and LED Safety Guidelines and Warnings for the MX150).

Ensure that you have the following parts and tools available:

  • Electrostatic bag or an antistatic mat

  • Rubber safety caps to cover the transceiver and fiber-optic cable connector

  • Dust cover to cover the port

The transceivers for the MX150 are hot-removable and hot-insertable field-replaceable units (FRUs). You can remove and replace them without powering off the device or disrupting device functions.

To remove a transceiver from the MX150:

  1. Place the antistatic bag or antistatic mat on a flat, stable surface.
  2. Label the cable connected to the transceiver so that you can reconnect it correctly.
    Laser Warning:

    Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to transceivers emit laser light that can damage your eyes.

    Laser Warning:

    Do not leave a fiber-optic transceiver uncovered except when inserting or removing a cable. The rubber safety cap keeps the port clean and prevents accidental exposure to laser light.

    CAUTION:

    Do not bend fiber-optic cables beyond their minimum bend radius. Bending the cables beyond their minimum bend radius can damage the cables and cause problems that are difficult to diagnose.

  3. Remove the cable connected to the transceiver (see Disconnecting a Fiber-Optic Cable from an MX150). Cover the transceiver and the end of each fiber-optic cable connector with a rubber safety cap immediately after disconnecting the fiber-optic cables.
  4. Using your fingers, pull the ejector lever away from the transceiver to unlock the transceiver.
    CAUTION:

    Before removing the transceiver, make sure you open the ejector lever completely until you hear it click. Doing this prevents damage to the transceiver.

  5. Grasp the transceiver ejector lever and gently slide the transceiver approximately 0.5 in. (1.3 cm) straight out of the port (see Figure 1).
    CAUTION:

    To avoid electrostatic discharge (ESD) damage to the transceiver, do not touch the connector pins at the end of the transceiver.

  6. Using your fingers, grasp the body of the transceiver and pull it straight out of the port.
  7. Place the transceiver in the electrostatic bag or on the antistatic mat placed on a flat, stable surface.
  8. Place the dust cover over the empty port.

Installing a Transceiver in an MX150

Before you begin installing a transceiver in an MX150, ensure that you have taken the necessary precautions for safe handling of lasers (see Laser and LED Safety Guidelines and Warnings for the MX150).

Ensure that you have a rubber safety cap available to cover the transceiver.

The transceivers for the MX150 are hot-removable and hot-insertable field-replaceable units (FRUs). You can remove and replace them without powering off the device or disrupting device functions.

To install a transceiver in an MX150 :

CAUTION:

To avoid electrostatic discharge (ESD) damage to the transceiver, do not touch the connector pins at the end of the transceiver.

  1. Remove the transceiver from its bag.
  2. Check to see whether the transceiver is covered by a rubber safety cap. If it is not, cover the transceiver with a rubber safety cap.
    Laser Warning:

    Do not leave a fiber-optic transceiver uncovered except when inserting or removing a cable. The rubber safety cap keeps the port clean and prevents accidental exposure to laser light.

  3. If the port in which you want to install the transceiver is covered with a dust cover, remove the dust cover and save it in case you need to cover the port later.
  4. Using both hands, carefully place the transceiver in the empty port. The connectors must face the device chassis.
    CAUTION:

    Before you slide the transceiver into the port, ensure that the transceiver is aligned correctly. Misalignment might cause the pins to bend, making the transceiver unusable. See Figure 2 for the correct orientation for your device.

  5. Slide the transceiver in gently until it is fully seated. See Figure 2 for an example of inserting an SFP or SFP+ transceiver.
  6. Remove the rubber safety cap when you are ready to connect the cable to the transceiver.
    Laser Warning:

    Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to transceivers emit laser light that can damage your eyes.

Maintaining Fiber-Optic Cables in an MX150

To maintain fiber-optic cables in MX150:

  • When you unplug a fiber-optic cable from a transceiver, place rubber safety caps over the transceiver and on the end of the cable.

  • Anchor fiber-optic cable to avoid stress on the connectors. When attaching a fiber-optic cable to a transceiver, be sure to secure the fiber-optic cable so that it is not supporting its own weight as it hangs to the floor. Never let a fiber-optic cable hang free from the connector.

  • Do not bend fiber-optic cables beyond their minimum bend radius. Bending the cables beyond their minimum bend radius can damage the cables and cause problems that are difficult to diagnose.

  • Frequent plugging and unplugging of fiber-optic cables in and out of optical instruments can damage the instruments, which are expensive to repair. Attach a short fiber extension to the optical equipment. Any wear and tear due to frequent plugging and unplugging is then absorbed by the short fiber extension, which is easier and less expensive to replace than the instruments.

  • Keep fiber-optic cable connections clean. Microdeposits of oil and dust in the canal of the transceiver or cable connector can cause loss of light, reduction in signal power, and possibly intermittent problems with the optical connection.

    To clean the transceiver canal, use an appropriate fiber-cleaning device such as RIFOCS Fiber Optic Adaptor Cleaning Wands (part number 946). Follow the directions in the cleaning kit you use.

    After cleaning the transceiver, make sure that the connector tip of the fiber-optic cable is clean. Use only an approved alcohol-free fiber-optic cable cleaning kit such as the Cletop-S® Fiber Cleaner. Follow the directions in the cleaning kit you use.

Connecting a Fiber-Optic Cable to an MX150

Before you connect a fiber-optic cable to an optical transceiver installed in an MX150, ensure that you have taken the necessary precautions for safe handling of lasers (see Laser and LED Safety Guidelines and Warnings for the MX150).

You can connect fiber-optic cables to the field-replaceable unit (FRU) optical transceivers installed in MX150 routers.

To connect a fiber-optic cable to an optical transceiver installed in an MX150:

Laser Warning:

Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to transceivers emit laser light that can damage your eyes.

Laser Warning:

Do not stare into the laser beam or view it directly with optical instruments even if the interface has been disabled.

  1. If the fiber-optic cable connector is covered by a rubber safety cap, remove the cap. Save the cap.
  2. If the optical transceiver is covered by a rubber safety cap, remove the cap. Save the cap.
  3. Insert the cable connector into the optical transceiver (see Figure 3).
  4. Secure the cables so that they are not supporting their own weight. Place excess cable out of the way in a neatly coiled loop. Placing fasteners on a loop helps cables maintain their shape.
    CAUTION:

    Do not bend fiber-optic cables beyond their minimum bend radius. Bending the cables beyond their minimum bend radius can damage the cables and cause problems that are difficult to diagnose.

    CAUTION:

    Do not let fiber-optic cables hang free from the connector. Do not allow fastened loops of cables to dangle, which stresses the cables at the fastening point.
