Figure 4: QFX10000 Control Board

The QFX10016 features 16 horizontal line card slots and supports line rate for each line
card. The line cards combine a Packet Forwarding Engine (PFE) and Ethernet interfaces
enclosed in a single assembly. The QFX10000 line card architecture is based on a number
of identical, independent PFE slices, each with 500 Gbps full-duplex throughput. Line
cards are FRUs that can be installed in the line card slots labeled
bottom) on the front of the switch chassis. All line cards are hot-removable and
hot-insertable.
Four line cards are available for the QFX10016:
QFX10000-36Q–provides 36 ports of 40-gigabit QSFP+. Twelve ports are designed
to be 100-Gigabit capable using QSFP28. Each of the 40-Gigabit QSFP+ can be
configured as either a native 40-Gigabit port or four 10-Gigabit ports using a breakout
cable. With breakout cables, the line card supports a maximum of 144 logical 10-Gigabit
Ethernet ports.
QFX10000-30C–provides 30 ports of either 100-gigabit or 40-gigabit QSFP28. The
ports autodetect the type of transceiver installed and set the configuration to the
appropriate speed. Each of the 40-gigabit ports can be configured as either a native
40-gigabit port or four 10-gigabit ports using a breakout cable. With breakout cables,
the line card supports a maximum of 120 logical 10-Gigabit Ethernet ports.
QFX10000-60S-6Q–provides 60 SFP+ ports that can be configured for either 1-gigabit
or 10-gigabit speeds. The card also provides six flexible configuration ports for
100-gigabit and 40-gigabit speeds. Of the six flexible configuration ports, two ports
have QSFP28 sockets that support either 100-gigabit or 40-gigabit speeds. The
remaining four ports have QSFP+ sockets that can be configured as either a native
40-gigabit port or four 10-gigabit ports using a breakout cable. With breakout cables,
the line card supports a maximum of 84 logical 10-Gigabit Ethernet ports.
QFX10K-12C-DWDM-provides 6 coherent dense wavelength-division multiplexing
(DWDM) ports with built-in optics. The card supports MACsec security features and
provides a flexible rate modulation at 100 Gbps, 150 Gbps, and 200 Gbps speeds.
