    QFX5100-24Q Layer 3 Switch

    Juniper’s QFX5100-24Q-3AFI is a 24-port QFX5100 switch that measures 1 rack unit (RU). All 24 ports on the device are compatible with QSFP+ optics and support up to 40G Ethernet.

    The total number of ports can be increased with breakout cables. In fact, each QSFP+ port can be split into four 10G Ethernet connections, increasing the total number of available ports to 96. 

    The port density can be increased even more by adding expansion modules. The QFX5100-24Q-3AFI has two expansion module slots. There are two expansion modules that are compatible with the QFX5100-24Q-3AFI switch: the EX4600-EM-8F and the QFX-EM-4Q.

    The EX4600-EM-8F adds another eight SFP+ slots and the QFX-EM-4Q adds another four QSFP+ slots. Adding two QFX-EM-4Q modules increases the total QSFP+ port density to 32.

    In addition, on the QFX-EM-4Q module, two of the slots can be broken out into four SFP+ ports, which increases the total number of available 10G Ethernet ports to 104. This can be achieved with two EX4600-EM-8F modules as well. Expansion modules must be purchased separately.

    The QFX5100-24Q-3AFI has a maximum capacity of 2.56 Tbps.

    There is one key feature that makes this particular switch model stand out. The QFX5100-24Q-3AFI includes three — not two — management ports. One is an RJ-45 and the other two are SFP ports. All three management ports support up to 1G Ethernet.

    The QFX5100-24Q-3AFI is designed with back-to-front airflow. It has an AC power supply and its power consumption is 161 W.
