Maintaining MX480 Interface Modules

 

Maintaining MX480 DPCs

Purpose

The router can have up to six Dense Port Concentrators (DPCs) mounted horizontally in the DPC card cage at the front of the chassis. For optimum router performance, verify the condition of the DPCs.

Action

On a regular basis:

  • Check the LEDs on the craft interface directly above each DPC slot. The green LED labeled OK lights steadily when a DPC is functioning normally.

  • Check the OK/FAIL LED on the DPC. For more information, seeMX Series Interface Module Reference . If the DPC detects a failure, the DPC sends an alarm message to the Routing Engine.

  • Check the status of installed DPCs by issuing the CLI show chassis fpc command to check the status of installed DPCs. As shown in the sample output, the value Online in the column labeled State indicates that the DPC is functioning normally:

    user@host> show chassis fpc

    For more detailed output, add the detail option. The following example does not specify a slot number, which is optional:

    user@host> show chassis fpc detail
  • Issue the CLI show chassis fpc pic-status command. The DPC slots are numbered 0 through 5, bottom to top:

    user@host> show chassis fpc pic-status

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

Holding an MX480 DPC

When carrying a DPC, you can hold it either vertically or horizontally.

Note

A DPC weighs 14.5 lb (6.6 kg). Be prepared to accept the full weight of the DPC as you lift it.

To hold a DPC vertically:

  1. Orient the DPC so that the faceplate faces you. To verify orientation, confirm that the text on the DPC is right-side up and the electromagnetic interference (EMI) strip is on the right-hand side.
  2. Place one hand around the DPC faceplate about a quarter of the way down from the top edge. To avoid deforming the EMI shielding strip, do not press hard on it.
  3. Place your other hand at the bottom edge of the DPC.

If the DPC is horizontal before you grasp it, place your left hand around the faceplate and your right hand along the bottom edge.

To hold a DPC horizontally:

  1. Orient the DPC so that the faceplate faces you.
  2. Grasp the top edge with your left hand and the bottom edge with your right hand.

You can rest the faceplate of the DPC against your body as you carry it.

As you carry the DPC, do not bump it against anything. DPC components are fragile.

Never hold or grasp the DPC anywhere except places that this document indicates. In particular, never grasp the connector edge, especially at the power connector in the corner where the connector and bottom edges meet. See Figure 1.

Figure 1: Do Not Grasp the Connector Edge
Do Not Grasp
the Connector Edge

Never carry the DPC by the faceplate with only one hand.

Do not rest any edge of a DPC directly against a hard surface (see Figure 2).

Do not stack DPCs.

Figure 2: Do Not Rest the DPC on an Edge
Do Not Rest the
DPC on an Edge

If you must rest the DPC temporarily on an edge while changing its orientation between vertical and horizontal, use your hand as a cushion between the edge and the surface.

Storing an MX480 DPC

You must store a DPC as follows:

  • In the router

  • In the container in which a spare DPC is shipped

  • Horizontally and sheet metal side down

When you store a DPC on a horizontal surface or in the shipping container, always place it inside an antistatic bag. Because the DPC is heavy, and because antistatic bags are fragile, inserting the DPC into the bag is easier with two people. To do this, one person holds the DPC in the horizontal position with the faceplate facing the body, and the other person slides the opening of the bag over the DPC connector edge.

If you must insert the DPC into a bag by yourself, first lay the DPC horizontally on a flat, stable surface, sheet metal side down. Orient the DPC with the faceplate facing you. Carefully insert the DPC connector edge into the opening of the bag, and pull the bag toward you to cover the DPC.

Never stack a DPC under or on top of any other component.

  2. Installing an MX480 DPC

Removing an MX480 DPC

A DPC weighs up to 13.1 lb (5.9 kg). Be prepared to accept its full weight.

To remove a DPC (see Figure 3):

  1. Have ready a replacement DPC or DPC blank panel and an antistatic mat for the DPC. Also have ready rubber safety caps for each DPC you are removing that uses an optical interface.
  2. Attach an 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 DPC so that you can later reconnect the cables to the correct ports.
  4. Use one of the following methods to take the DPC offline:
    • Press and hold the corresponding DPC 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 CLI Explorer.

  5. Disconnect the cables from the DPC.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 you are inserting or removing 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. 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 cable management brackets to prevent the cables from developing stress points.
  8. Simultaneously turn both of the ejector handles counterclockwise to unseat the DPC.
  9. Grasp the handles, and slide the DPC straight out of the card cage halfway.
  10. Place one hand around the front of the DPC and the other hand under it to support it. Slide the DPC completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag.Caution

    The weight of the DPC is concentrated in the back end. Be prepared to accept the full weight—up to 13.1 lb (5.9 kg)—as you slide the DPC out of the chassis.

    When the DPC 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 DPCs 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.

  11. If you are not reinstalling a DPC into the emptied DPC slot within a short time, install a blank DPC panel over the slot to maintain proper airflow in the DPC card cage.Caution

    After removing a DPC from the chassis, wait at least 30 seconds before reinserting it, removing a DPC from a different slot, or inserting a DPC into a different slot.

Figure 3: Removing a DPC
Removing a DPC

Installing an MX480 DPC

A DPC weighs up to 14.5 lb (6.6 kg). Be prepared to accept its full weight.

To install a DPC (see Figure 4):

  1. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  2. Place the DPC on an antistatic mat, or remove it 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. If it does not, cover the transceiver with a safety cap.
  5. Orient the DPC so that the faceplate faces you.
  6. Lift the DPC into place, and carefully align the sides of the DPC with the guides inside the card cage.
  7. Slide the DPC all the way into the card cage until you feel resistance.
  8. Grasp both ejector handles, and rotate them clockwise simultaneously until the DPC is fully seated.
  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 cables connected to a transceiver emit laser light that can damage your eyes.

  10. Insert the cables into the cable connector ports on each DPC (see Figure 5).
  11. Arrange the cable in the cable management brackets 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 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.

  12. Use one of the following methods to bring the DPC online:
    • Press and hold the corresponding DPC 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 fpc slot slot-number online

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

    Caution

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

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

Maintaining MX480 FPCs

Purpose

The MX480 router can have up to three Flexible PIC Concentrators (FPCs) installed horizontally in the front of the chassis. For optimum router performance, verify the condition of the FPC.

Action

On a regular basis:

  • Check the LEDs on the craft interface directly above the FPC. The green LED labeled OK lights steadily when an FPC is functioning normally.

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

  • Issue the CLI show chassis fpc command to check the status of the installed FPC. As shown in the sample output, the value Online in the column labeled State indicates that the FPC is functioning normally:

    user@host> show chassis fpc

    For more detailed output, add the detail option. The following example does not specify a slot number, which is optional:

    user@host> show chassis fpc detail
  • Issue the CLI show chassis fpc pic-status command. The following example shows an FPC installed in DPC slots 0, and 1:

    user@host> show chassis fpc pic-status
    Note

    An FPC takes up two DPC slots when installed on an MX Series router. The slot number corresponds to the lowest numbered DPC slot.

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

Holding an MX480 FPC

Caution

Many components on the FPC are fragile. Failure to handle FPCs as specified in this document can cause irreparable damage.

Note

An FPC configured with PICs installed can weigh as much as 18 lb (8.2 kg). Be prepared to accept the full weight of the FPC as you lift it.

Caution

To prevent damage when handling or carrying FPCs:

  • As you carry the FPC, do not bump it against anything. FPC components are fragile.

  • Do not grasp the FPC anywhere except places that this document indicates. In particular, never grasp the connector edge, especially at the power connector in the corner where the connector and bottom edges meet (see Figure 6).

    Figure 6: Do Not Grasp the Connector Edge
    Do Not Grasp the
Connector Edge
  • Do not carry the FPC by the faceplate with only one hand (see Figure 7).

    Figure 7: Do Not Carry an FPC with Only One Hand
    Do Not
Carry an FPC with Only One Hand
  • Do not rest any edge of an FPC directly against a hard surface (see Figure 8). If you must rest the FPC temporarily on an edge while changing its orientation between vertical and horizontal, use your hand as a cushion between the edge and the surface.

    Figure 8: Do Not Rest the FPC on an Edge
    Do Not Rest the

You hold an FPC horizontally when installing it into the chassis or an equipment rack.

If the FPC is horizontal before you grasp it, place your left hand around the faceplate and your right hand along the bottom edge.

To hold an FPC horizontally:

  1. Orient the FPC so that the faceplate faces you.
  2. Grasp the top edge with your left hand and the bottom edge with your right hand.

Storing an MX480 FPC

When not installed in the routing platforms, FPCs must be either stored in the container in which a spare FPC is shipped or stored horizontally with the component-side up on a flat, stable surface. When you store an FPC on a horizontal surface or in the shipping container, always place it inside an antistatic bag. Because the FPC is heavy and because antistatic bags are fragile, inserting the FPC into the bag is easier with two people. The storage guidelines are as follows:

  • When storing an FPC with two people, one person holds the FPC in the horizontal position with the faceplate facing their body, the other person slides the opening of the bag over the FPC connector edge.

  • When storing an FPC with one person, you must insert the FPC into a bag by yourself. First lay the FPC horizontally on a flat, stable surface, component-side up. Orient the FPC with the faceplate facing you. Carefully insert the FPC connector edge into the opening of the bag, and pull the bag toward you to cover the FPC.

Caution

To prevent damage when storing FPCs:

  • Never lay an FPC component-side down.

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

    Caution

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

You can also verify correct FPC and PIC functioning by issuing the show chassis fpc and show chassis fpc pic-status commands described in Maintaining MX480 FPCs and Maintaining MX480 PICs.

Figure 11: Installing an FPC
Installing an FPC

Maintaining MX480 MICs

Purpose

For optimum router performance, verify the condition of the MICs.

Action

On a regular basis:

  • Check the LEDs on MIC faceplates. The meaning of the LED states differs for various MICs. For more information, see the MX Series Interface Module Reference. If the MPC that houses the MIC detects a MIC failure, the MPC generates an alarm message to be sent to the Routing Engine.

  • Issue the CLI show chassis fpc pic-status command. The MIC slots in an MPC are numbered PIC 0/1 and PIC 2/3, left to right:

    user@host> show chassis fpc pic-status

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

Replacing an MX480 MIC

  2. Installing an MX480 MIC

  3. Installing an MX480 Dual-Wide MIC

Removing an MX480 MIC

MICs are hot-insertable and hot-removable. When you remove a MIC, the router continues to function, although the MIC interfaces being removed no longer function.

The MICs are located in the MPCs installed in the front of the router. A MIC weighs less than 2 lb (0.9 kg).

To remove a MIC (see Figure 12 and Figure 13):

  1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the MIC. If the MIC connects to fiber-optic cable, have ready a rubber safety cap for each transceiver and cable.
  2. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  3. Use one of the following methods to take the MIC offline:
    • Press its online/offline button. Use a narrow-ended tool that fits inside the opening that leads to the button. Press and hold the button until the MIC OK/FAIL LED goes off (about 5 seconds).

    • Issue the following CLI command:

      user@host> request chassis mic fpc-slot mpc-slot mic-slot mic-slot offline

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

  4. Label the cables connected to the MIC so that you can later reconnect each cable to the correct MIC.
  5. Disconnect the cables from the MIC. If the MIC 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 you are inserting or removing cable. The safety cap keeps the port clean and prevents accidental exposure to laser light.

  6. Arrange the cable 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. 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.

  7. On the MPC, pull the ejector lever that is adjacent to the MIC you are removing away from the MPC faceplate. Pulling the ejector lever disconnects the MIC from the MPC.Note

    To remove a dual-wide MIC that takes up both MIC slots, you must pull both ejector levers away from the MPC faceplate.

  8. Grasp the handles on the MIC faceplate, and slide the MIC out of the MPC card carrier. Place it in the electrostatic bag or on the antistatic mat.
  9. If you are not reinstalling a MIC into the emptied MIC slot within a short time, install a blank MIC panel over the slot to maintain proper airflow in the MPC card cage.

Maintaining MX480 MPCs

Purpose

The router can have up to six MPCs mounted horizontally in the card cage at the front of the chassis. For optimum router performance, verify the condition of the MPCs.

Action

On a regular basis:

  • Check the LEDs on the craft interface directly above each MPC slot. The green LED labeled OK lights steadily when an MPC is functioning normally.

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

  • Issue the CLI show chassis fpc command to check the status of installed MPCs. As shown in the sample output, the value Online in the column labeled State indicates that the MPC is functioning normally:

    user@host> show chassis fpc

    For more detailed output, add the detail option. The following example does not specify a slot number, which is optional:

    user@host> show chassis fpc detail
  • Issue the CLI show chassis fpc pic-status command. The MPC slots are numbered 0 through 5, bottom to top:

    user@host> show chassis fpc pic-status

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

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

  5. Disconnect the cables from the MICs installed in 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 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. If a MIC uses fiber-optic cable, immediately cover each transceiver and the end of each cable with a rubber safety cap.
  7. Arrange the disconnected cables in the cable management brackets to prevent the cables from developing stress points.
  8. Simultaneously turn both the ejector handles counterclockwise to unseat the MPC.
  9. Grasp the handles, and slide the MPC straight out of the card cage halfway.
  10. Place one hand around the front of the MPC (the MIC housing) and the other hand under it to support it. Slide the MPC completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag.Caution

    The weight of the MPC 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 MPC out of the chassis.

    When the MPC 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 MPCs 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.

  11. If necessary, remove each installed MIC from the MPC.
  12. After you remove each MIC, immediately place it on an antistatic mat or in an electrostatic bag.
  13. If you are not reinstalling an MPC into the emptied line card slots within a short time, install a blank DPC panel over each slot to maintain proper airflow in the card cage.Caution

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

    • Press its online/offline button. Use a narrow-ended tool that fits inside the opening that leads to the button. Press and hold the button until the AS MXC LED goes out (about 5 seconds).

    • Issue the following CLI command:

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

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

  4. Slide the AS MXC out of the AS MLC card carrier by pulling the handles, and place it in the electrostatic bag or on the antistatic mat.
  5. If you are not reinstalling an AS MXC into the emptied AS MXC slot within a short time, install a blank AS MXC panel over the slot to maintain proper airflow in the AS MLC card cage.

Installing an MX480 AS MXC

To install an AS MXC (see Figure 27):

  1. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  2. Align the notches in the connector at the rear of the AS MXC with the notches in the AS MXC slot (slot 1—the bottom slot in the AS MLC), and then slide the AS MXC in until it lodges firmly in the AS MLC.Caution

    Slide the AS MXC straight into the slot to avoid damaging the components on the bottom of the AS MXC.

  3. Use one of the following methods to bring the AS MXC online:
    • Press the AS MXC offline/online button until the LED light turns green.

    • Issue the following CLI command:

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

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

    The normal functioning status LED confirms that the AS MXC is online. You can also verify correct AS MXC functioning by issuing the show chassis fpc pic-status command.

Maintaining Cables That Connect to MX480 DPCs, MPCs, MICs, or PICs

Purpose

For optimum router performance, verify the condition of the cables that connect to the DPCs, MPCs, MICs, or PICs.

Action

On a regular basis:

  • Use the cable management brackets to support cables and prevent cables from dislodging or developing stress points.

  • Place excess cable out of the way in the cable management brackets. Do not allow fastened loops of cable to dangle from the connector or cable management brackets, because this stresses the cable at the fastening point. Putting fasteners on the loops helps to maintain their shape.

  • Keep the cable connections clean and free of dust and other particles, which can cause drops in the received power level. Always inspect cables and clean them if necessary before connecting an interface.

  • Label both ends of the cables to identify them.

The following guidelines apply specifically to fiber-optic cables:

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

  • Anchor fiber-optic cables to avoid stress on the connectors. Be sure to secure fiber-optic cables so that they do not support their own weight as they hang to the floor. Never let fiber-optic cable hang free from the connector.

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

  • Frequent plugging and unplugging of fiber-optic cable into and out of optical instruments can cause damage to the instruments that is expensive to repair. Instead, 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 easy and inexpensive to replace.

  • Keep fiber-optic cable connections clean. Small microdeposits of oil and dust in the canal of the transceiver or cable connector could cause loss of light, reducing signal power and possibly causing intermittent problems with the optical connection.

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

    After you clean an optical 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 Opptex Cletop-S Fiber Cleaner. Follow the directions for the cleaning kit you use.
