Routing and Control Board
The routing and control board (RCB) (see Figure 5 on page 10 ) contains a Routing Engine and is
responsible for the system management and system control in QFX10016. See "QFX10000 Routing and
Control Board Description" on page 86 . RCBs are FRUs that are installed in the front of the chassis in
the slots labeled CB0 and CB1. The base configuration has a single RCB; the fully-redundant
configuration has two RCBs. The RCB also contains Precision Time Protocol (PTP) ports and four Media
Access Control Security (MACsec) capable ports. See
"QFX10016 Components and Configurations" on
page 18 . The base configuration has a single RCB; the fully redundant configuration has two RCBs.

Line Cards
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 0 through 15 (top to bottom) on the front of the switch chassis. All line cards are hot-removable
and hot-insertable.
Five 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 96 logical 10-Gigabit
Ethernet ports.
