ESD grounding strap
Phillips screwdriver, number 2
A replacement optional module or cover panel
An antistatic bag or antistatic mat
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 84 on page 212):
Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD
1.
point on the chassis.
Unscrew both captive screws on the faceplate of the expansion module by using your
2.
fingers. If you are unable to unscrew the captive screws by using your fingers, use the
screwdriver.
Hold the handle and gently pull the expansion module toward you and out of the
3.
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 84 on page 212).
Place the expansion module in an antistatic bag or on an antistatic mat placed on a
4.
flat, stable surface.
If you are not replacing the expansion module with an optional module, install the
5.
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 83 on page 212 shows removing a QFX-EM-4Q expansion module from the port
panel of a QFX5100-24Q device.
