Maintaining QFX10000 Line Cards

Removing a QFX10000 Line Card

QFX10000 line cards are field-replaceable units (FRUs) that can be installed in the line card slots on the front of the 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.

If you have the optional line-card cable management system, it is not necessary to remove the cable management system before removing the line card.

Before you remove a line card from the switch chassis:

Ensure that you have the following parts and tools available to remove a line card from a QFX10000 chassis:

  • ESD grounding strap

  • An electrostatic bag or an antistatic mat

    Note:

    Placing a line card in an electrostatic bag might require a second person to assist with sliding the line card into the bag.

  • Replacement line card or a cover for the empty slot

To remove a line card from a QFX10000 switch chassis:

  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 above the status LEDs on the switch chassis (see Figure 1).

  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. Unscrew the line card from the chassis by continually turning the handles to the left until the line card is fully unseated. See Figure 3.

  6. Using the handles, slide the line card halfway out of 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 electrostatic bag or on the antistatic mat placed on a flat, stable surface.

    CAUTION:

    Each QFX10000 line card weighs between 20.9 lb (9.5 kg) and 27.3 lb (12.4 kg). Be prepared to support the full weight as you slide the line card out of the chassis.

  7. Grasp both sides of line card at midpoint and remove the line card from the chassis. Either have someone assist you in putting the line card into the electrostatic bag or rest the card on the antistatic mat. Take care not to bump or store the line cards on the connectors. See Figure 4.

  8. If you are not installing a line card in the emptied line card slot within a short time, install a cover 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.

Installing a QFX10000 Line Card

QFX10000 line cards are field-replaceable units (FRUs) that can be installed in any of the line card slots on the front of the 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.

Before you install a line card in the switch chassis:

To install a line card in the switch chassis:

  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 above the status LED panel on the front of the switch chassis. See Figure 5 and Figure 6.

  2. Remove the cover panel by grasping the handles and pulling straight out to expose the slot for the line card. See Figure 7.

    CAUTION:

    Do not lift the line card by holding the edge connectors or the handles on the faceplate. Neither the handles or the edge connectors can support the weight of the line card. Lifting the line card by the handles or edge connectors might bend them, which would prevent the line cards from being properly seated in the chassis. See Figure 8.

  3. Remove the line card from the electrostatic bag and inspect it for any damage before installing it into the chassis.
  4. Grasp and lift the line card by the sides.
  5. Slide the line card all the way into the slot until the handle holes align. See Figure 9.

  6. Screw the line card into the chassis by rotating the handles until the card is fully seated and the handles are vertical.
  7. Bring the line card online:

     

You can install the optional cable management kit after the card is installed.

Installing the QFX10000 Cable Management System

The QFX10000 cable management system is an optional kit that can be ordered to organize and protect optical cabling attached to the line cards. After a card is installed, you can still remove the line card without needing to remove the cable management system.

Ensure that you have the following parts and tools available to install the QFX10000 cable management system on a line card:

  • Phillips (+) screwdriver, number 2

To install the cable management system (see Figure 10):

  1. Open the shipping carton for cable management system and check that you have:

    • Two handle extensions

    • One cable tray

    Figure 10: Cable Management System ComponentsCable Management System Components
  2. Use the Phillips screwdriver to loosen and remove the screws on the two line card handles (see Figure 11).
    Figure 11: Removing the Handle ScrewsRemoving the Handle Screws
  3. Replace the blue cap on the line card handle with the two handle extensions (see Figure 12).
    Figure 12: Adding Handle ExtensionsAdding Handle Extensions
  4. Tighten the screws into the handle extensions.
  5. Snap open the blue clips on the ends of the cable tray with your hands.
  6. Place the cable tray across the front of the line card so that the two ends of the cable tray are under the handle extensions.
  7. Snap to close the blue clips of the cable tray around the handle extensions (see Figure 13).
    Figure 13: Adding the Cable TrayAdding the Cable Tray
  8. Drape and tie the optical cables to the side (see Figure 14). Another option is to drape some of the cables under the handle extension and some cables over the handle extension.
