Removing an Expansion Module from a QFX5100 Device

Before you begin removing an expansion module from the switch:

Ensure that you have the following parts and tools available:

  • ESD grounding strap

  • Phillips screwdriver, number 2

  • A replacement optional module or cover panel

  • An antistatic bag or antistatic mat

The expansion modules used in QFX5100-24Q and QFX5100-24Q-AA devices are hot-removable and hot-insertable field-replaceable units (FRUs): You can remove and replace them without powering off the switch or disrupting switch functions.

Note:

You must take the QFX5100-24Q-AA switch offline, before replacing the QFX-PFA-4Q expansion module.

CAUTION:

We recommend that you install either a replacement optional module or a cover panel in the empty module slot to avoid chassis overheating and dust accumulation.

To remove an expansion module from the switch (see Figure 1 and Figure 2):

  1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
  2. Unscrew both captive screws on the faceplate of the expansion module by using your fingers. If you are unable to unscrew the captive screws by using your fingers, use the screwdriver.
  3. Hold the handle and gently pull the expansion module toward you and out of the module slot. For a QFX5100-24Q-AA switch, unscrew the captive screws of the ejector handles and pull the expansion module toward you and out of the module slot (see Figure 2).
  4. Place the expansion module in an antistatic bag or on an antistatic mat placed on a flat, stable surface.
  5. If you are not replacing the expansion module with an optional module, install the cover panel over the slot.
    Note:

    After you have removed an expansion module, wait for at least 5 seconds before you install an expansion module. If you do not wait for at least 5 seconds, the interfaces on the expansion module might not come up.

Figure 2 shows removing a QFX-PFA-4Q expansion module from the port panel of a QFX5100-24Q-AA switch.

Note:

You must take the QFX-PFA-4Q offline before replacing it.
