The Nexus 93108TC-FX3 and Nexus 93108TC-FX3P are high-performance switches from Nexus 9000 series, tailored for modern data centers and enterprise deployments. While both models are designed to meet rigorous demands, they feature distinct capabilities and use cases, offering flexibility depending on network requirements.

Overview of Both Models #

Nexus 93108TC-FX3 #

• Ports: 48 fixed downlink ports and 6 uplink ports.
• Downlink Capabilities: Supports speeds of 100 Mbps, 1 Gbps, and 10 Gbps.
• Uplink Speeds: Uplink ports support 40 Gbps and 100 Gbps.
• Use Case: Best suited for traditional data center and enterprise environments where devices have consistent speed requirements, such as servers or access points operating at 1 Gbps or 10 Gbps.

Nexus 93108TC-FX3P #

• Ports: Also has 48 fixed downlink ports and 6 uplink ports.
• Downlink Capabilities: Adds support for multi-gigabit speeds (100 Mbps, 1 Gbps, 2.5 Gbps, 5 Gbps, and 10 Gbps).
• Uplink Speeds: Uplink port specifications are the same (40 Gbps and 100 Gbps).
• Use Case: Ideal for environments with mixed device types, such as offices or hybrid cloud setups, where multi-gigabit devices are deployed.

Key Differences #

1. Multi-Gigabit Support:

• The FX3P model supports 2.5 Gbps and 5 Gbps speeds on downlink ports, ensuring compatibility with next-generation devices like Wi-Fi 6 access points.

1. Future-Proofing:

• The FX3P provides better future-proofing for organizations adopting Wi-Fi 6/6E or IoT devices requiring more than 1 Gbps.

1. Flexibility:

• The FX3P is more versatile for networks with diverse device requirements, while the FX3 is optimized for traditional setups with consistent speed demands.

Shared Features #
