Maintaining ACX6160 Transceivers and Fiber-Optic Cables

Removing a QSFP28 Transceiver

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

Ensure that you have the following parts and tools available:

  • An antistatic bag or an antistatic mat

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

  • A dust cover to cover the port or a replacement transceiver

See Figure 1 to remove a QSFP28 transceiver.

The 28-Gbps quad small form-factor pluggable (QSFP28) transceivers for Juniper Network devices are hot-insertable and hot-removable components. Removing a QSFP28 transceiver does not interrupt the device functioning, but the removed QSFP28 transceiver no longer receives or transmits data.

Figure 1: 28-Gbps Quad Small Form-Factor Pluggable (QSFP28) Transceiver28-Gbps Quad Small Form-Factor Pluggable (QSFP28) Transceiver

To remove a QSFP28 transceiver (see Figure 1):

  1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the transceiver. Have ready a rubber safety cap for the QSFP28 transceiver and the cable.
  2. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to the ESD point on the chassis.
  3. Label the cable connected to the QSFP28 transceiver so that you can later reconnect the cable to the correct transceiver.
  4. Disconnect the cable from the transceiver. Immediately cover the transceiver and the end of the cable connector with a rubber safety cap.
    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 cable connected to a transceiver emit laser light that can damage your eyes.

    CAUTION:

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

  5. Arrange the cable in the cable management system to prevent it from dislodging or developing stress points. Secure the cable so that it does not support its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop in the cable management system. Placing fasteners on the loop helps to maintain its shape.
    CAUTION:

    Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

  6. Pull the transceiver’s rubber handle straight back. The locking pins on the transceiver are automatically released. Place the transceiver on the antistatic mat or in the electrostatic bag.

Removing a CFP2 Transceiver

The C form-factor pluggable (CFP) transceivers for Juniper Networks devices are hot-removable and hot-insertable FRUs. You can remove and replace them without powering off the device or disrupting device functions.

Note:

After you remove a transceiver or when you change the media-type configuration, wait for 6  seconds for the interface to display the operational commands.

To remove a CFP2 transceiver from the ACX6160:

  1. Place the antistatic bag or antistatic mat on a flat, stable surface.
  2. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the device.
  3. 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. An arc smaller than a few inches in diameter can damage the cables and cause problems that are difficult to diagnose.

  4. Remove the cable connected to the transceiver. Cover the transceiver and the end of each fiber-optic cable connector with a rubber safety cap immediately after disconnecting the fiber-optic cables.
  5. To remove the transceiver:
    1. Loosen the screws on the transceiver by using your fingers.
    2. Grasp the screws on the transceiver and gently slide the transceiver approximately 0.5  in. (1.3 cm) straight out of the port.
      CAUTION:

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

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

Installing a QSFP28 Transceiver

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

Note:

After you insert a transceiver or after you change the media-type configuration, wait for 6 seconds for the interface to display operational commands.

Note:

We recommend that you use only optical transceivers and optical connectors purchased from Juniper Networks with your Juniper Networks device.

CAUTION:

The Juniper Networks Technical Assistance Center (JTAC) provides complete support for Juniper-supplied optical modules and cables. However, JTAC does not provide support for third-party optical modules and cables that are not qualified or supplied by Juniper Networks. If you face a problem running a Juniper device that uses third-party optical modules or cables, JTAC may help you diagnose host-related issues if the observed issue is not, in the opinion of JTAC, related to the use of the third-party optical modules or cables. Your JTAC engineer will likely request that you check the third-party optical module or cable and, if required, replace it with an equivalent Juniper-qualified component.

Use of third-party optical modules with high-power consumption (for example, coherent ZR or ZR+) can potentially cause thermal damage to or reduce the lifespan of the host equipment. Any damage to the host equipment due to the use of third-party optical modules or cables is the users’ responsibility. Juniper Networks will accept no liability for any damage caused due to such use.

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

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

To install a replacement QSFP28 transceiver:

  1. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the device.
  2. Verify that a rubber safety cap covers the QSFP28 transceiver, installing one if necessary.
  3. Orient the transceiver over the port so that the transceiver connector faces the appropriate direction.
  4. Slide the QSFP28 transceiver into the port until the locking pins lock in place. If there is resistance, remove the transceiver and flip it so that the connector faces the other direction and slide it into the slot. Ensure that the transceiver is seated snugly in the port.
  5. Remove the rubber safety cap from the transceiver and the end of the cable connector, and insert the cable into 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 cable connected to a transceiver emit laser light that can damage your eyes.

    CAUTION:

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

  6. Arrange the cable in the cable management system to prevent the cable from dislodging or developing stress points. Secure the cable so that it does not support its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop in the cable management system. Placing fasteners on the loop helps to maintain its shape.
    CAUTION:

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

    CAUTION:

    Avoid bending fiber-optic cable beyond its minimum bend radius. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose.

  7. Verify that the port status LEDs on the front panel indicate that the QSFP28 transceiver is functioning correctly.

To install a CFP2 transceiver:

CAUTION:

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

  1. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the chassis.
  2. Remove the transceiver from its bag.
  3. Check to see whether the transceiver is covered with 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.

  4. 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. If you are hot-swapping a transceiver, wait for at least 10 seconds after removing the transceiver from the port before installing a new transceiver.
  5. Using both hands, carefully align the transceiver in front of the empty port. The connectors must face the 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.

  6. Slide the transceiver in gently until it is fully seated. Tighten the captive screws on the transceiver by using your fingers.
  7. 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.

Disconnecting a Fiber-Optic Cable from the ACX6160

Before you disconnect a fiber-optic cable from an ACX6160, ensure that you have taken the necessary precautions for safe handling of lasers (see Radiation from Open Port Apertures Warning and Laser and LED Safety Guidelines and Warnings).

Ensure that you have the following parts and tools available:

  • Rubber safety cap to cover the transceiver

  • Rubber safety cap to cover the fiber-optic cable connector

The ACX6160 has optical transceivers to which you can connect fiber-optic cables.

To disconnect a fiber-optic cable from an optical transceiver installed in the ACX6160:

  1. (Recommended) Disable the port in which the transceiver is installed by including the disable statement at the [edit interfaces] hierarchy level for the specific interface:
    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.

  2. Carefully unplug the fiber-optic cable connector from the transceiver.
  3. 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.

  4. Cover the fiber-optic cable connector with the rubber safety cap.

Connecting a Fiber-Optic Cable to the ACX6160

Before you connect a fiber-optic cable to an ACX6160, ensure that you have taken the necessary precautions for safe handling of lasers (see Radiation from Open Port Apertures Warning and Laser and LED Safety Guidelines and Warnings).

The ACX6160 has optical transceivers to which you can connect fiber-optic cables.

To connect a fiber-optic cable to an optical transceiver installed in the ACX6160:

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.
  4. Secure the cable so that it does not support its 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.

Maintaining Fiber-Optic Cables in an ACX6160

To maintain fiber-optic cables in an ACX6160:

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

  • Anchor fiber-optic cables 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 does not support 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.
