Maintaining the EX9200 Line Cards

Handling and Storing Line Cards

Components in the line cards are fragile. To avoid damaging the line cards, follow the procedures in this topic. The procedures use the following terms to describe the four edges of the line cards:

  • Faceplate—Edge of the line card that has connectors into which you insert the transceivers.

  • Connector edge—Edge opposite the faceplate.

  • Top edge—Edge at the top of the line card when the line card is vertical.

  • Bottom edge—Edge at the bottom of the line card when the line card is vertical.

CAUTION:

Failure to handle line cards as specified in these procedures can cause irreparable damage to them.

Holding a Line Card

You must hold a line card horizontally when installing it in the chassis. You may hold a line card vertically or horizontally when carrying it.

CAUTION:

Be prepared to support the full weight as you slide the line card into the chassis.

To hold a line card vertically:

  1. Orient the line card so that the faceplate faces you. To verify the orientation, confirm that the text on the line card is right-side up.
  2. Place one hand around the line card faceplate about a quarter of the way down from the top edge. Do not press hard on it.
  3. Place the other hand at the bottom edge of the line card.

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

To hold a line card horizontally:

  1. Orient the line card 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 line card against your body as you carry it.

CAUTION:

Take care not to hit the line card against any object as you carry it. Line card components are fragile.

Never hold or grasp the line card anywhere except the places mentioned in these procedures. In particular, never grasp the connector edge. See Figure 1.

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

Never carry the line card while holding the faceplate with only one hand.

Do not rest any edge of a line card directly against a hard surface. See Figure 2.

Figure 2: Do Not Rest the Edge of a Line Card on a Hard SurfaceDo Not Rest the Edge of a Line Card on a Hard Surface

If you must rest a line card temporarily on an edge, place a cushion between the edge and the surface.

Do not stack line cards on top of one another or on top of any other component. Place each line card separately in an antistatic bag or on an antistatic mat placed on a flat, stable surface.

Storing a Line Card

You must store a line card in the chassis or in a spare shipping container, horizontally and sheet metal side down. Do not stack line cards on top of one another or on top of any other component. Place each line card separately in an antistatic bag or on an antistatic mat placed on a flat, stable surface.

Note:

Because a line card is heavy, and because antistatic bags are fragile, inserting the line card into the bag is best done with two people, each to do one of the following steps.

To insert a line card into an antistatic bag:

  1. Hold the line card in the horizontal position with the faceplate facing you.
  2. Slide the opening of the bag over the line card connector edge.

If you must insert the line card into a bag by yourself:

  1. Lay the line card horizontally on a flat, stable surface, sheet metal side down.

  2. Orient the line card with the faceplate facing you.

  3. Carefully insert the line card connector edge into the opening of the bag and pull the bag toward you to cover the line card.

Maintaining Line Card Cables

Components in the line cards are fragile. To extend the lives of your line card cables and to avoid problems that can result from cable damage, follow these procedures:

To maintain line card cables:

  • Place excess cable out of the way. Do not allow fastened loops of cable to dangle from the connector. Placing fasteners on the loops helps retain 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 a port.

  • Label both ends of line card cables to identify them.

Unpacking a Line Card Used in an EX9200 Switch

Before you unpack a line card:

The line cards for EX9200 switches are rigid sheet-metal structures that house the line card components including network ports. The line cards are shipped in a cardboard carton, secured with foam packing material.

CAUTION:

The line cards are maximally protected inside the shipping carton. Do not unpack the line cards until you are ready to install them in the switch chassis.

To unpack a line card (see Figure 3):

  1. Move the shipping carton to a staging area as close to the installation site as possible.
  2. Position the carton so that the arrows are pointing up.
  3. Open the top flaps on the shipping carton.
  4. Pull out the packing material, which holds the line card in place.
  5. Remove the line card from the antistatic bag.
  6. Save the shipping carton and packing materials in case you need to move or ship the line card later.

Removing a Line Card from an EX9200 Switch

Before you begin removing a line card from an EX9200 switch:

Ensure that you have the following parts and tools available to remove a line card from an EX9200 switch chassis:

  • ESD grounding strap

  • An antistatic bag or an antistatic mat

  • Replacement line card or a cover panel and its captive screws to cover the empty slot

EX9200 switches have field-replaceable unit (FRU) line cards that can be installed in the line card slots on the front of the switch chassis. The line cards are hot-insertable and hot-removable: You can remove and replace them without powering off the switch or disrupting switch functions. However, we recommend that you take them offline before removing them.

To remove a line card from an EX9200 switch:

  1. Place the antistatic bag or antistatic mat on a flat, stable surface.
  2. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the switch chassis.
  3. Label the cables connected to each port on the line card so you can reconnect the cables to the correct ports.
  4. Take the line card offline by issuing the following CLI command:
  5. Rotate the ejector handles simultaneously counterclockwise to unseat the line card.
  6. Grasp the handles, and gently slide the line card halfway out of the chassis.

    See Handling and Storing Line Cards.

    CAUTION:

    Do not lift the line card by holding the ejector levers on the faceplate or the edge connectors. The levers cannot support the weight of the line card. Lifting the line cards by the levers might bend them. Bent levers prevent the line cards from being properly seated in the chassis.

    CAUTION:

    Do not stack line cards on top of one another or on top of any other component. Place each line card separately in the antistatic bag or on the antistatic mat placed on a flat, stable surface.

    CAUTION:

    The weight of line cards in EX9200 switches is in the range 14–19.4 lb (6.6–8.8 kg). Be prepared to support the full weight as you slide the line card into the chassis.

  7. Place one hand around the faceplate of the line card and the other hand under the line card to support it. Taking care not to touch line card components, pins, leads, or solder connections, gently slide the line card completely out of the chassis and place it in an antistatic bag or on its own antistatic mat placed on a flat, stable surface.
    CAUTION:

    After removing a line card, wait for at least 30 seconds before installing a line card or removing another line card.

  8. If you are not installing a line card in the emptied line card slot within a short time, install a cover panel over the slot. Do this to protect the interior of the chassis from dust or other foreign substances and to ensure that the airflow inside the chassis is not disrupted.

Figure 4 shows removing a line card from an EX9204 switch. The procedure and orientation of the line card are the same for EX9208. The procedure is the same for EX9214 switch; however, the orientation of the line cards is different—it is installed vertically into the top and bottom of the chassis.

Installing a Line Card in an EX9200 Switch

Before you begin installing a line card in the switch:

Ensure that you have the following parts and tools available to install a line card in the switch:

  • ESD grounding strap

EX9200 switches have field-replaceable unit (FRU) line cards that can be installed in the line card slots on the front of the switch chassis. The line cards are hot-insertable and hot-removable: You can remove and replace them without powering off the switch or disrupting switch functions. However, we recommend that you take them offline before removing them.

To install a line card in the switch:

  1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the switch chassis.
  2. If the slot has a cover panel on it, rotate the ejector handles simultaneously counterclockwise to unseat the cover panel.
  3. Grasp the ejector handles, and slide the cover panel out of the chassis. Save the cover panel for later use.
  4. Taking care not to touch line card components, pins, leads, or solder connections, remove the line card from its bag.
    CAUTION:

    Do not lift the line card by holding the ejector handles on the faceplate or the edge connectors. The ejector handles cannot support the weight of the line card. Lifting the line card by the ejector handles might bend them. Bent ejector handles prevent line cards from being properly seated in the chassis.

  5. Ensure that the ejector handles are not in the locked position. If necessary, flip the ejector handles outward.
  6. Place one hand around the faceplate of the line card and the other hand under the line card to support it.
    CAUTION:

    The weight of line cards in EX9200 switches is in the range 14–19.4 lb (6.6–8.8 kg). Be prepared to support the full weight as you slide the line card into the chassis.

    Before you slide the line card into the slot on the switch chassis, ensure the line card is aligned correctly. Misalignment might cause the pins to bend, making the line card unusable.

  7. Lift the line card, and position it in the chassis with the faceplate facing you and the sides of the line card aligned with the guides in the line card slot on the switch chassis.
  8. Make sure the handles stay in the open position and gently slide the line card fully into the slot using both hands.
  9. Rotate both of the ejector handles inward to seat the line card.
  10. Bring the line card online by pressing the corresponding line card control button on the craft interface or by issuing the following CLI command:
Note:

On EX9204, EX9208, and EX9214 switches, when a line card is brought online, if the aggregate interface is initialized before the child interface is marked as part of the aggregate interface, there might be a loss of traffic from the aggregate interface for up to 30 seconds and the CPU usage of the line card installed on the switch might go up to 100%.

Figure 5 shows installing a line card in an EX9204 switch. The procedure and orientation of the line card are the same for EX9208. The procedure is the same for EX9214 switch; however, the orientation of the line card is different—it is installed vertically in the chassis.

Figure 5: Installing a Line CardInstalling a Line Card

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

Note:

If you have a Juniper J-Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/support/tools/updateinstallbase/ . Failure to do so can result in significant delays if you need replacement parts. This note does not apply if you replace existing components with the same type of component.

Removing a MIC from an EX9200-MPC Line Card

Before you begin removing a MIC from an EX9200-MPC line card:

Ensure that you have the following parts and tools available:

  • (If you will replace the MIC by installing only one EX9200-10XS-MIC or EX9200-20F-M-MIC) A septum if it is not installed in the line card and screws to secure the septum

  • One or two MIC slot cover panels and screws for installing the MIC slot cover panels. You must install both the MIC slot cover panels if you will not install any MIC, or install one cover panel in the empty portion of the MIC slot if you will install only one EX9200-10XS-MIC or EX9200-20F-M-MIC.

  • Rubber safety caps to cover transceivers

  • ESD grounding strap

  4. If there are transceivers installed in the MIC, remove them (see Remove a Transceiver).
  5. Take the MIC offline by pressing the power button on the MIC until the OK/FAIL LED on the MIC is unlit or by issuing the following CLI command:
  6. If you are removing an EX9200-10XS-MIC or EX9200-20F-MIC, grasp the MIC ejector lever on the faceplate of the line card that is adjacent to the MIC and pull it outward until the MIC is fully unseated (see Figure 6). If you are removing an EX9200-40T-MIC, grasp the MIC ejector levers on either side of the faceplate of the line card and pull them outward simultaneously until the MIC is fully unseated (see Figure 7).
  7. Grasp the handles on the MIC faceplate and slide the MIC out of the line card.
    CAUTION:

    Do not stack MICs on top of one another or on top of any other component. Place each MIC separately in the antistatic bag or on the antistatic mat placed on a flat, stable surface.

  8. Place the MIC in an antistatic bag or on its own antistatic mat placed on a flat, stable surface.
  9. Install both the MIC slot cover panels if you will not install any MIC in the MIC slots, or install one cover panel in the empty portion of the MIC slot if you will install only one EX9200-10XS-MIC or EX9200-20F-MIC. Do this to protect the interior of the line card and the switch chassis from dust or other foreign substances and to ensure that the airflow inside the line card and the switch chassis is not disrupted.

    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 you are inserting or removing cable. The safety cap keeps the port clean and protects your eyes from accidental exposure to laser light.

  5. If any transceiver is installed in the MIC, ensure that you cover it by using a rubber safety cap.
  6. Align the MIC with the guides located along the sides of the MIC slot.
    CAUTION:

    Before you slide the MIC into the slot, ensure that the MIC is aligned correctly. Misalignment might cause the pins to bend, making the MIC unusable.

  7. Slide the MIC into the slot gently until it is fully seated (see Figure 10 or Figure 11).
  8. Push the MIC ejector lever on the line card that is adjacent to the MIC slot in which you are installing the MIC until the MIC is secured in position.
  9. If you are installing only one EX9200-10XS-MIC or EX9200-20F-MIC, install a cover panel over the empty MIC slot and secure it with the captive screws by using the screwdriver. Do this to protect the interior of the chassis from dust or other foreign substances and to ensure that the airflow inside the chassis is not disrupted.
  10. Bring the MIC online by pressing the power button on the MIC until the OK/FAIL LED on the MIC is lit green. You can also bring the MIC online by issuing the following CLI command:
