Network topologies supported

The Cisco Catalyst C9300-NM-2Q is a 2-slot 40-gigabit Ethernet network module designed for use with the Cisco Catalyst 9300 Series switches. It provides two 40-Gigabit Ethernet QSFP+ (Quad Small Form-Factor Pluggable Plus) ports that can support various network topologies.

Here are some of the network topologies that can be supported by the C9300-NM-2Q module:

• Point-to-Point: The C9300-NM-2Q can be used to connect two switches directly using a QSFP+ cable. This topology is typically used for high-speed data center interconnects or for connecting switches in a high-availability cluster.
• Spine-Leaf: In a spine-leaf topology, the C9300-NM-2Q can be used as a spine switch to connect multiple leaf switches in a data center. This provides a highly scalable and resilient network design.
• Ring: The C9300-NM-2Q can also be used in a ring topology to create a redundant network design. In this topology, each switch is connected to two other switches in a ring configuration, providing redundancy in case of a link failure.
• Mesh: In a mesh topology, each switch is connected to every other switch in the network. This topology provides high availability and redundancy but can be complex to manage and configure.

Cooling requirements of the 2 Slots Module

The Cisco Catalyst C9300-NM-2Q network module provides two slots for installing 40 Gigabit Ethernet (40G) QSFP+ transceiver modules on Cisco Catalyst 9300 Series switches. The module supports a range of cooling requirements to maintain optimal performance and reliability.

The cooling requirements of the C9300-NM-2Q module depend on the type of QSFP+ transceiver module installed and the operating conditions of the switch. The QSFP+ transceiver modules can be either passive or active, with the active modules requiring more power and generating more heat than the passive ones.

To ensure proper cooling, it is recommended to install active QSFP+ transceiver modules in the first slot of the module, as this slot has direct airflow from the switch's fan modules. Passive modules can be installed in the second slot or both slots, but the airflow may not be as direct, so it's important to ensure proper airflow and cooling in the switch's chassis.

In addition to the proper installation of the QSFP+ transceiver modules, the switch's cooling system must also be adequate to dissipate the heat generated by the modules. The Cisco Catalyst 9300 Series switches have built-in fan modules that provide front-to-back airflow to cool the modules and other components in the switch. It's important to ensure that the fan modules are functioning properly and that the switch has adequate ventilation to allow for proper airflow.
