TheQFX5100-24Q-AA switch supports the double-wide QFX-PFA-4Q expansion module,
in addition to the QFX-EM-4Q (see Figure 78 on page 207) and the EX4600-EM-8S (see
Figure 79 on page 207). The QFX-PFA-4Q module adds four 40-Gigabit Ethernet QSFP+

NOTE: When an expansion module is installed in the switch or an existing
expansion module is replaced with another expansion module, the switch
detects the ports on the expansion module. The switch creates the required
interfaces when transceivers are installed in these ports.
Before you begininstalling an expansion module inthe switch, ensure that you have taken
the necessary precautions to prevent electrostatic discharge (ESD) damage (see
“Prevention of Electrostatic Discharge Damage” on page 263).
Ensure that you have the following parts and tools available:
•
ESD grounding strap. If a grounding strap is not available, follow the alternative
grounding method described in Step 1 of the following procedure.
•
Phillips (+) screwdriver, number 2
To install an expansion module in a QFX5100-24Q or a QFX5100-24Q-AA device (see
Figure 81 on page 209 and Figure 82 on page 209):
1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD
point on the chassis.
If a grounding strap is not available, hold the expansion module in its antistatic bag
in one hand and touch the exposed metallic part of the switch with the other hand to
ground yourself and the component.
2. If the module slot has a cover panel on it, remove the cover panel by using the
screwdriver and save it for later use.
3. Taking care not to touch module components, pins, leads, or solder connections,
remove the expansion module from its bag.
4. Loosen the captive screws on the front faceplate of the expansion module by using
your fingers. If you are unable to loosen the captive screws by using your fingers, use
the screwdriver.
