The port panel of the QFX5100-24Q device consists of 24 quad small-form factor pluggable plus (QSFP+)
ports. Each QSFP+ socket can be configured to support 40 GbE or as a set of 4 independent 10 GbE ports
using breakout cables (channelization mode). In standalone mode, any of the 24 ports 0 through 23 can
be configured as either uplink or access ports. The QFX5100-24Q device has two module bays for the
optional expansion modules, QFX-EM-4Q or EX4600-EM-8F. The QFX-EM-4Q, can add a total of 8
additional QSFP+ ports to the chassis and the EX4600-EM-8F can provide 8 additional 10-Gigabit Ethernet
Enhanced Small Form-Factor Pluggable (SFP+) ports. The QFX-EM-4Q ports can also be configured as
either access ports or as uplinks, but only ports 0 and 2 can be channelized using port mode.
Figure 16 on page 32 shows the port panel of the QFX5100-24Q device.
