Install and Remove QFX5700 Line Card Components

Line cards on the QFX5700 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.

How to Handle and Store QFX5700 Line Cards

The QFX5700 line cards have fragile components. To avoid damaging the line cards, be sure you follow safe handling practices.

How to Hold QFX5700 Line Cards

Pay proper attention to the way you hold the line cards. Line cards are installed horizontally, and it is best to hold them by the sides of the units when they are not in the chassis.

When you walk with a line card in hand:

  1. Orient the line card so that the faceplate is toward you.
  2. Grasp each side of the unit firmly as you slide the unit out of the chassis.
  3. Take care not to strike the unit against any object as you carry it.
    CAUTION:

    The RCBs are installed horizontally and in an upside down position. Never hold the line card by the connector edge. The connectors are fragile and the line card won’t seat properly if the connector is damaged.

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

    Do not stack line cards on top of one another or on top of any other component.

  5. Place each line card separately in an electrostatic bag or on an antistatic mat placed on a flat, stable surface.

How to Store a Line Card

You must store line cards either in the chassis or in a spare shipping container, horizontally and sheet-metal side down. Don’t stack these units on top of one another or on top of any other component. Place each unit separately in an antistatic bag or on an antistatic mat placed on a flat, stable surface.

Note:

Because these units are heavy and because antistatic bags are fragile, inserting the line card into the bag is best done by two people.

To insert a line card into an antistatic bag:

  1. Hold the unit horizontally with the faceplate toward you.
  2. Slide the opening of the bag over the connector edge.

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

  1. Lay the unit horizontally on an antistatic mat that is on a flat, stable surface with the sheet-metal side down.

  2. Orient the unit with the faceplate toward you.

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

Install a QFX5700 RCB Card

Before you install a line card in the switch chassis:

  • Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.

  • Ensure that you know how to handle and store the line card.

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

  • Ensure that the switch has sufficient power to power the line card while maintaining its n+1 power redundancy. To determine whether the switch has enough power available for the line card, use the show chassis power-budget-statistics command.

  • 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 chassis:

Note:

You need to install the RCB in an “upside-down” position.

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other end of the strap to one of the ESD points on the chassis. An ESD point is located above the status LED panel on the front of the switch chassis. See Figure 1.

  2. See Figure 2.

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

  6. If the system is not powered, the line card automatically comes online when power is applied to the system. If you are adding the line card to a running system, issue the following command to bring the line card online:

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

Remove a QFX5700 RCB

If you have the optional line-card cable management system, it’s 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 taken the necessary precautions to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.

  • If there are any optical cables (including transceivers installed in the line card), remove them before you remove the line card.

  • Ensure that you know how to handle and store the line card.

  • Ensure that you have the following parts and tools available to remove a line card from a QFX5700 chassis:

    • ESD grounding strap

    • An antistatic 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 QFX5700 switch chassis:

  1. Place the antistatic bag or antistatic mat on a flat, stable surface.
  2. Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other end of the strap to one of the ESD points on the chassis. An ESD point is located above the status LED panel on the front of the switch chassis.
  3. Label the cables connected to each port on the line card so that you can reconnect the cables to the correct ports.
  4. Issue the following CLI command to take the line card offline:
  5. Unscrew the line card from the chassis. See Figure 4.
    Figure 4: Remove a QFX5700 RCBRemove a QFX5700 RCB
  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 antistatic bag or on the antistatic mat placed on a flat, stable surface.

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

Install a QFX5700 FEB Board

Before installing a FEB board, you will need to remove the fan tray.

Note:

To install a FEB board in FEB1, remove Fan tray 1 and install FEB1.

Figure 5: Installing a FEB BoardInstalling a FEB Board

There are two FEB slots, and each FEB board is plugged in from the rear side.

Note:

The fan tray removal shown in the picture above is for representative purposes only. Remove Fan Tray 1 to install FEB1 and remove Fan Tray 0 to install FEB0.
