EX4600-EM-8F–Each module adds eight 10 Gigabit SFP+ ports. See Figure 146 on page 435.
Figure 146: EX4600-EM-8F Expansion Module
The QFX5100-24Q device is configured for the QFX-EM-4Q by default, but any combination of the two
modules is supported. Expansion modules can be hot-inserted or hot-removed. However, when an
EX4600-EM-8F is inserted instead of the default QFX-EM-4Q, the new configuration causes the PFE to
reboot and all of the interfaces to go down temporarily, causing a short disruption in traffic.
The QFX5100-24Q-AA switch supports the double-wide QFX-PFA-4Q expansion module, in addition to
the QFX-EM-4Q (see Figure 145 on page 435) and the EX4600-EM-8F (see Figure 146 on page 435). The
QFX-PFA-4Q module adds four 40-Gigabit Ethernet QSFP+ ports (see Figure 147 on page 435).

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.
