Maintaining QFX10000 Switch Interface Boards

Removing a QFX10000 Switch Interface Board

A QFX10008 and QFX10016 switch has six Switch Interface Boards (SIBs) that are located in the middle of the chassis behind the fan trays. SIB 0 through SIB 2 are located behind the left fan tray and SIB 3 through SIB 5 are located behind the right fan tray. You must remove the appropriate fan tray to access the failing SIB. See Removing a QFX10008 Fan Tray.

Ensure you have the following equipment on hand before replacing a SIB:

  • Electrostatic bag or antistatic mat

  • Electrostatic discharge (ESD) grounding strap

To remove a SIB (see Figure 4):

  1. Take the SIB offline using the request chassis sib slot slot number offline command.
    Note:

    If you suspect the SIB is faulty and want to ensure packets do not flow through the SIB, power down the SIB instead of taking the SIB offline. To power down the SIB, use the set chassis sib power-off slot slot number command. To bring up a new SIB up in the slot, you must delete the old configuration using the delete chassis sib power-off slot slot number command.

  2. Place an electrostatic bag or an antistatic mat on a flat, stable surface.
  3. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis. There is an ESD point located next to the protective earthing terminal and below PSU 5 on the QFX10008 rear panel (see Figure 1) and below PSU_9 on the QFX10016 (see Figure 2.

  4. Remove the appropriate fan tray (see Removing a QFX10008 Fan Tray).
  5. Loosen the captive screws at the top and bottom of the card.
  6. Grasp both ejector handles and spread them apart. The SIB slides about a quarter of the way out of the slot. See Figure 3.

  7. Grasp the ejector handle with one hand and place your other hand under the SIB for support as you slide the SIB out of the slot (see Figure 4 and Figure 5).

  8. Support the SIB as you rotate the SIB 90 degrees and place it on the antistatic mat with the printed circuit (PC) board facing upward. Be careful not to bump or handle the SIB by the connectors. If you do not have an antistatic mat, have another person help you slide the electrostatic bag over the SIB before placing it on the stable surface. See Figure 6.
    CAUTION:

    Do not stack hardware components on top of one another after you remove them. Place each component on an antistatic mat resting on a stable, flat surface.

A QFX10008 and QFX10016 switch has six Switch Interface Boards (SIBs) that are located in the middle of the chassis behind the fan trays. SIB 0 through SIB 2 are located behind the left fan tray, and SIB 3 through SIB 5 are located behind the right fan tray. You must remove the appropriate fan tray to install a SIB. See Removing a QFX10008 Fan Tray.

Ensure you have the following equipment on hand before installing a SIB:

  • Electrostatic bag or antistatic mat

  • Electrostatic discharge (ESD) grounding strap

To install a SIB:

  1. Place an electrostatic bag or an 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 chassis. There is an ESD point located next to the protective earthing terminal and below PSU 5 on the QFX10008 rear panel (see Figure 7) and below PSU_9 on the QFX10016 rear panel (see Figure 8).

  3. Remove the appropriate fan tray (see Removing a QFX10008 Fan Tray).
  4. Either remove the failing SIB (see Removing a QFX10000 Switch Interface Board) or remove the cover by grasping each side of the plate and pulling straight out (see Figure 9 for an example using the QFX10008).

  5. Lift the SIB by the handle with one hand and support the lower edge with the other hand.
  6. Holding the SIB vertically, slide the SIB into the open slot until the ejector handles engage and start to close.
  7. Grasp the two ejector handles and fold them inward until they latch to seat the SIB (see Figure 10 for the QFX10008 and Figure 11 for the QFX10016).

  8. Hand-tighten the captive screws.
  9. Bring the SIB online using the request chassis sib slot slot number online command.

    You can check the status of the SIB using the show chassis fabric sibs and the show chassis fabric plane-location commands. For example:

    Note:

    If you completely powered off the SIB using the set chassis sib power-off slot slot command, you must delete the configuration in order to bring the SIB online. To delete the configuration and bring a replacement SIB online, use the delete chassis sib power-off slot slot number command.
