To remove an expansion module from the switch (see Figure 150 on page 439 and Figure 151 on page 440 ):
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 151 on page 440 ).
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.
