Maintaining the EX6210 Line Card

 

Removing a Line Card from an EX6200 Switch

EX6200 switches have field-replaceable unit (FRU) line cards that can be installed in the line card slots or the Switch Fabric and Routing Engine (SRE) module slots on the front of the switch chassis. See Slot Numbering for an EX6210 Switch. The line cards are hot-insertable and hot-removable: You can remove and replace them without powering off the switch or disrupting switch functions.

Note

We recommend that you take the line cards offline before removing them.

Before you begin removing a line card from an EX6200 switch:

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

  • ESD grounding strap

  • Phillips (+) screwdriver, number 2

  • An antistatic bag or an antistatic mat

  • Replacement line card or the appropriate cover panel to cover the empty slot

To remove a line card from the switch (see Figure 2):

  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. The ESD point is located on the front top panel on the right side of the switch.
  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:
    user@switch> request chassis fpc slot slot-number offline
  5. Unscrew the captive screws on the faceplate of the line card by turning them counterclockwise using the screwdriver.
  6. Grasp both the ejector levers on the faceplate of the line card and pull them outward simultaneously until they are in the open position and the line card is unseated. See Figure 1 for the open position of the line card ejector lever.
    Figure 1: Open and Closed Positions of the Line Card Ejector Lever
    Open and Closed Positions of the Line Card Ejector Lever
  7. Grasp both the ejector levers and gently slide the line card halfway out of the chassis.

    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

    Be prepared to support the full weight of the line card as you slide it out of the chassis.

  8. 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.

  9. For slots 0 through 3 and 6 through 9:

    If you are not installing a line card in the emptied slot within a short time, install the line card cover panel over the slot and secure it with captive screws by using the screwdriver.

    For slots 4 and 5:

    If you are not installing a line card or an SRE module in the emptied slot within a short time, install the Switch Fabric and Routing Engine (SRE) module cover panel (SRE module filler panel and line card cover panel) over the slot and secure each panel with 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.

    Caution

    Do not overtighten the screws. Applying excessive force might damage the screws.

Installing a Line Card in an EX6200 Switch

EX6200 switches have field-replaceable unit (FRU) line cards that can be installed in the line card slots or the Switch Fabric and Routing Engine (SRE) module slots on the front of the switch chassis. See Slot Numbering for an EX6210 Switch. The line cards are hot-insertable and hot-removable: You can remove and replace them without powering off the switch or disrupting switch functions.

Note

We recommend that you take the line cards offline before removing them.

Note

Installation of a line card in the SRE module slots (slots 4 and 5) in an EX6200 switch is supported in Junos OS Release 12.1 or later.

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

  • Phillips (+) screwdriver, number 2

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. The ESD point is located on the front panel of the switch on the right side.
  2. Determine the slot in which you want to install the line card:
    • For slots 0 through 3 or slots 6 through 9:

      If the line card slot has a cover panel on it, use the screwdriver to remove the captive screws on each side of the cover panel. Save the cover panel and the screws for later use.

    • For slots 4 and 5:

      If the SRE module slot has a SRE module cover panel (line card cover panel and SRE module filler panel) on it, use the screwdriver to remove the captive screws on each side of the line card cover panel to remove it. Save the line card cover panel and the screws for later use. Do not remove the SRE module filler panel (see Figure 3 ).

      Note

      You must install the SRE module filler panel in slots 4 or 5, if you install a line card in either of these slots, to ensure proper airflow in the chassis.

    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 card by the levers might bend them. Bent levers prevent line cards from being properly seated in the chassis.

  3. Taking care not to touch line card components, pins, leads, or solder connections, remove the line card from its bag.Note

    Inspect the connector edge of the line card for physical damage. Installing a damaged line card might damage the switch.

  4. Grasp the ejector levers on the faceplate of the line card and pull them outward until they are fully open (see Figure 4).

and Closed Positions of the Line Card Ejector Lever
  5. Place one hand around the faceplate of the line card and the other hand under the line card to support it.Caution

    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.

  6. 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.
  7. Make sure the levers stay in the open position (see Figure 4) and gently slide the line card fully into the slot using both hands.
  8. Grasp the ejector levers on the line card and push them inward simultaneously until the ejectors are perpendicular to the faceplate of the line card (see Figure 4) and the line card is fully seated (see Figure 5).

  9. Tighten the captive screws on the faceplate of the line card by using the screwdriver.Caution

    Do not overtighten the screws. Applying excessive force might damage the screws or line card.

  10. Verify that the ON LED starts blinking in green. When the ON LED is lit steadily, the line card is ready for use. Caution

    After the ON LED is lit steadily, wait for at least 30 seconds before installing another line card or removing a line card.

  11. Verify that the SRE module filler panel is installed in slots 4 or 5, if a line card is installed in either of these slots, to ensure proper airflow in the chassis.

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.

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 6.

Figure 6: Do Not Grasp the Connector Edge
Do 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 7.

Figure 7: Do Not Rest the Edge of a Line Card on a Hard Surface
Do 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.
