What type of chassis do smaller Junos devices typically fall into?

Smaller Junos devices typically fall into the category of fixed port chassis. This design is characterized by a set number of ports that are permanently attached to the chassis, making them simpler and more compact compared to modular chassis. Fixed port chassis are ideal for environments that require a straightforward deployment, as they usually come pre-configured with a specific number of interfaces suited for smaller networks or branch offices.

The choice of a fixed port chassis allows for easier maintenance and simplified operation since the hardware configuration is not subject to change or expansion. This setup can be more cost-effective for organizations that do not need the extensive scalability offered by modular designs, which are more suitable for larger and more complex networking needs.
