Replacing an MX2010 MPC and Adapter Card

 

Removing an MX2010 MPC with Adapter Card

An MPC with an adapter card weighs up to 25 lb (11.34 kg). Be prepared to accept its full weight.

To remove an MPC with an adapter card:

  1. Have ready a replacement MPC or blank panel and an antistatic mat. Also have ready rubber safety caps for each MPC you are removing that uses an optical interface.
  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  3. Label the cables connected to each port on the MPC so that you can later reconnect the cables to the correct ports.
  4. Use one of the following methods to take the MPC offline:
    • Press and hold the corresponding LC online button on the craft interface. The green OK LED next to the button begins to blink. Hold the button down until the LED goes off.

    • Issue the following CLI command:

      user@host>request chassis fpc slot slot-number offline

      For more information about the command, see the Junos OS System Basics and Services Command Reference  .

      Note

      When you issue the request chassis fpc slot slot-number offline command, the FRU loses power, and the system’s total power increases.

  5. Disconnect the cables from the MPC.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.

    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. Immediately cover each optical transceiver and the end of each fiber-optic cable with a rubber safety cap.
  7. Arrange the disconnected cables in the standard upper and lower cable managers to prevent the cables from developing stress points.
  8. Simultaneously turn both of the ejector handles outward to unseat the MPC along with the adapter card.
  9. Grasp the handles, and slide the combined cards straight out of the card cage halfway.
  10. Place one hand around the front of the combined cards and the other hand under it to support it. Slide the combined cards completely out of the chassis.Caution

    The weight of the MPC with the adapter card is concentrated in the back end. Be prepared to accept the full weight—up to 25 lb (11.34 kg)—as you slide the cards out of the chassis.

    When the combined cards are out of the chassis, do not hold the cards by the ejector handles, bus bars, or edge connectors. They cannot support the card’s weight.

    Do not stack the combined cards on top of one another after removal.

  11. Place each card (MCP and adapter card) individually in an electrostatic bag or on its own antistatic mat on a flat, stable surface.
  12. If you are not reinstalling both MPC and adapter card into the emptied slot within a short time, install a blank adapter card panel over the slot to maintain proper airflow in the card cage.Caution

    After removing both cards from the chassis, wait at least 30 seconds before reinserting it, removing an MPC and adapter card from a different slot, or inserting an MPC and adapter card into a different slot.

Removing an MX2010 MPC from the Adapter Card

An MPC without the adapter card weighs up to 18.35 lb (8.32 kg). Be prepared to accept its full weight.

To remove an MPC from the adapter card (see Figure 1):

  1. Have ready a replacement MPC and an antistatic mat for the MPC. Also have ready rubber safety caps for each MPC you are removing that uses an optical interface.
  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  3. Label the cables connected to each port on the MPC so that you can later reconnect the cables to the correct ports.
  4. Use one of the following methods to take the MPC offline:
    • Press and hold the corresponding MPC LC online button on the craft interface. The green OK LED next to the button begins to blink. Hold the button down until the LED goes off.

    • Issue the following CLI command:

      user@host>request chassis fpc slot slot-number offline

      For more information about the command, see the Junos OS System Basics and Services Command Reference  .

      Note

      When you issue the request chassis fpc slot slot-number offline command, the FRU loses power, and the system’s total power increases.

  5. Disconnect the cables from the MPC.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.

    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. Immediately cover each optical transceiver and the end of each fiber-optic cable with a rubber safety cap.
  7. Arrange the disconnected cables in the upper and lower cable managers to prevent the cables from developing stress points.
  8. Simultaneously turn both of the knobs counterclockwise to unseat the MPC from the adapter card.
  9. Grasp both the knobs, and slide the MPC straight out of the adapter card.
  10. Place one hand around the front of the MPC and the other hand under it to support it. Slide the MPC completely out of the adapter card.Caution

    The weight of the MPC without the adapter card is concentrated in the back end. Be prepared to accept the full weight—up to 18.35 lb (8.32 kg)—as you slide the MPC out of the adapter card.

    When the MPC is out of the adapter card, do not hold it by the knobs, bus bars, or edge connectors. They cannot support its weight.

    Do not stack MPCs on top of one another after removal.

  11. Place each adapter card individually in an electrostatic bag or on its own antistatic mat on a flat, stable surface.
  12. If you are not reinstalling an MPC into the emptied MPC slot within a short time, install a blank MPC panel over the slot to maintain proper airflow in the MPC card cage.Caution

    After removing an MPC from the adapter card, wait at least 30 seconds before reinserting it, removing an MPC from a different slot, or inserting an MPC into a different slot.

Installing an MX2010 MPC into an Adapter Card

An MPC weighs up to 25 lb (11.34 kg). Be prepared to accept its full weight.

To install an MPC (see Figure 4):

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  2. Remove the MPC from its electrostatic bag.
  3. Identify the slot on the router where it will be installed.
  4. Verify that each fiber-optic transceiver is covered with a rubber safety cap.
  5. Orient the MPC so that the faceplate faces you vertically.
  6. Lift the MPC into place, and carefully align the sides of the MPC with the guides inside the adapter card.
  7. Slide the MPC all the way into the adapter card until you feel resistance.
  8. Grasp both knobs, and rotate them clockwise simultaneously until the MPC is fully seated into the adapter card.
  9. Remove the rubber safety cap from each fiber-optic transceiver and cable.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.

  10. Insert the cables into the cable connector ports on each MPC (see Figure 5).
  11. Arrange the cable in the cable manager to prevent it from dislodging or developing stress points. Secure the cable so that it is not supporting its own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop. 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.

  12. Use one of the following methods to bring the MPC online:
    • Press and hold the corresponding MPC LC online button on the craft interface until the green OK LED next to the button lights steadily, in about 5 seconds.

    • Issue the following CLI command:

      user@host>request chassis adc slot slot-number online

      For more information about the command, see the Junos OS System Basics and Services Command Reference  .

      Note

      When you issue the request chassis adc slot slot-number online command, the FRU gets power, and the system’s total power decreases.

    Caution

    After the OK LED turns green, wait at least 30 seconds before removing the MPC again, removing an MPC from a different slot, or inserting a MPC in a different slot.

You can also verify that the MPC is functioning correctly by issuing the show chassis fpc and show chassis fpc pic-status commands.
