Line Card Components
The EX9253-6Q12C line card has:
• Six built-in QSFP+ ports, each of which can house a combination of QSFP+ transceivers or breakout
cables. These ports operate at 40 Gbps speed. By default, the ports operate with 4x10 Gbps
interfaces and support breakout cables. If you need to connect a QSFP+ transceiver to the port, you
must configure a 40 Gbps interface on the port by using the command set chassis fpc
slot port port-number 40g . The ports are labeled 0 through 5. The ports support rate selectability and
remote port identification.
• 12 built-in QSFP28 ports, each of which can house a combination of QSFP28 transceivers, QSFP+
transceivers, or breakout cables. These ports can operate at 40 Gbps and 100 Gbps speeds. By
default, the ports operate with 4x10 Gbps interfaces and support breakout cables. If you need to
connect a QSFP+ transceiver to the port, you must configure a 40 Gbps interface on the port. If you
need to connect a QSFP28 transceiver to the port, you must configure a 100 Gbps interface on the
port by using the command set chassis fpc
labeled 0 through 11. The ports support rate selectability and remote port identification.
• Port LEDs—One LED on each QSFP+ port and two LEDs on each QSFP28 port, which indicates the
link status and activity on the port. See
