Maintaining MX-SPC3 Services Card

 

Maintaining MX-SPC3 Services Card

Purpose

For optimum router performance, verify the condition of the MX-SPC3 Services Card. To maintain MX-SPC3s cards, perform the following procedures regularly.

Action

On a regular basis:

  • Check the LEDs on the craft interface corresponding to the slot for each MX-SPC3. The green LED labeled OK lights steadily when a MX-SPC3 is functioning normally.

  • Check the OK/FAIL LED on the MX-SPC3. If the MX-SPC3 detects a failure, the MX-SPC3 sends an alarm message to the Routing Engine.

  • Issue the CLI show chassis fpc command to check the status of installed MX-SPC3s.

    user@host> show chassis fpc

    For more detailed output, add the detail option.

    user@host> show chassis fpc detail

  • Issue the CLI show chassis fpc pic-status command.

    user@host> show chassis fpc pic-status

    For further description of the output from the command, see the CLI Explorer.

Replacing an MX-SPC3

Removing an MX-SPC3

The MX-SPC3 installs horizontally in the front of the MX240 & MX480 routers and vertically in the MX960 router. The MX-SPC3s are hot-insertable and hot-removable and the router continues to function when you remove an MX-SPC3.

A fully configured MX-SPC3 can weigh up to 18.35 lb (8.3 kg). Be prepared to accept its full weight.

To remove an MX-SPC3:

  1. Have ready a replacement MX-SPC3 or a blank panel and an antistatic mat for the MX-SPC3. Also have ready rubber safety caps for transceivers.
  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 cables connected to each port on the MX-SPC3 so that you can later reconnect the cables to the correct ports.
  4. Use one of the following methods to take the MX-SPC3 offline:

    • Press and hold the corresponding online button on the craft interface. The green OK/FAIL 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 CLI Explorer.

  5. Disconnect the cables from the MX-SPC3. If the MX-SPC3 uses fiber-optic cable, immediately cover each transceiver and the end of each cable with a rubber safety cap.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 a transceiver emit laser light that can damage your eyes.

    Caution

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

    Caution

    Avoid bending a 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. Arrange the disconnected cables in the cable manager to prevent the cables from developing stress points.
  7. Simultaneously turn both the ejector handles counterclockwise to unseat the MX-SPC3.
  8. Grasp the handles, and slide the MX-SPC3 straight out of the card cage halfway.
  9. Place one hand around the front of the MX-SPC3 and the other hand under it to support it. Slide the MX-SPC3 completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag.Caution

    The weight of the MX-SPC3 is concentrated in the back end. Be prepared to accept the full weight—up to 18.35 lb (8.3 kg)—as you slide the MX-SPC3 out of the chassis.

    When the MX-SPC3 is out of the chassis, do not hold it by the ejector handles, bus bars, or edge connectors. They cannot support its weight.

    Do not stack MX-SPC3s on top of one another after removal. Place each one individually in an electrostatic bag or on its own antistatic mat on a flat, stable surface.

  10. If you are not reinstalling an MX-SPC3 into the emptied line card slots within a short time, install a blank panel over each slot to maintain proper airflow in the card cage.Caution

    After removing an MX-SPC3 from the chassis:

    • Check the back panel connectors of the MX-SPC3 for damages. A damaged connector on the MX-SPC3 card can damage the chassis back plane.

    • Wait for at least 30 seconds before reinserting the MX-SPC3 into the same slot or inserting it into a different slot.

Installing an MX-SPC3

The MX-SPC3 installs horizontally in the front of the MX240 & MX480 routers and vertically in the MX960 router.

A fully configured MX-SPC3 can weigh up to 18.35 lb (8.3 kg). Be prepared to accept its full weight.

Caution

Before installing an MX-SPC3 into the chassis:

  • Check the back panel connectors of the MX-SPC3 for damages. A damaged connector on the MX-SPC3 card can damage the chassis back plane.

  • Wait for at least 30 seconds, before reinserting the MX-SPC3 into the same slot or inserting it into a different slot.

To install an MX-SPC3:

  1. 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.
  2. Place the MX-SPC3 on an antistatic mat.
  3. Locate the slot in the card cage in which you plan to install the MX-SPC3.
  4. Verify that each fiber-optic transceiver is covered with a rubber safety cap. If it does not, cover the transceiver with a safety cap.
  5. Orient the MX-SPC3 so that the faceplate faces you.
  6. Lift the MX-SPC3 into place, and carefully align first the bottom and then the top of the card with the guides inside the card cage.Caution

    When the MX-SPC3 is out of the chassis, do not hold it by the ejector handles, bus bars, or edge connectors. They cannot support its weight.

  7. Slide the MX-SPC3 all the way into the card cage until you feel resistance.
  8. Grasp both ejector handles, and rotate them clockwise simultaneously until the MX-SPC3 is fully seated.
  9. If the MX-SPC3 uses fiber-optic cable, remove the rubber safety cap from each 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 cables connected to a transceiver emit laser light that can damage your eyes.

  10. Insert the appropriate cables into the cable connector ports on MX-SPC3. Secure the cables so that they are not supporting their own weight. Place excess cable out of the way in a neatly coiled loop, using the cable management system. Placing fasteners on a loop helps to maintain its shape.Caution

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

    Caution

    Avoid bending a 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.

  11. Use one of the following methods to bring the MX-SPC3 online:

    • Press and hold the corresponding MX-SPC3 online button on the craft interface until the green OK/FAIL LED next to the button lights steadily, in about 5 seconds.

    • Issue the following CLI command:

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

      For more information about the command, see the CLI Explorer.

    Caution

    After the OK/FAIL LED lights steadily, wait at least 30 seconds before removing the MX-SPC3 again, removing an MX-SPC3 from a different slot, or inserting an MX-SPC3 in a different slot.
