Q: Does this switch support Power over Ethernet (PoE)?
A: No, the N3K-C3048-FA-L3 does not support PoE. It provides 48 standard Gigabit Ethernet ports without power delivery capability. If PoE is required, consider the Cisco Nexus 3048TP model instead.

Q: What does the FA designation mean in the model number?
A: The FA indicates Forward Airflow with port-side exhaust. This airflow direction is important for data center rack thermal management and ensures proper cooling when integrated into hot aisle/cold aisle configurations.

Q: What license is included with the L3 suffix?
A: The L3 suffix indicates this unit includes the LAN Enterprise license, which provides advanced Layer 3 routing features including OSPF, BGP, VXLAN, and enhanced security capabilities. A Base license is also required and typically included with the switch.

Q: What types of transceivers are supported in the SFP+ uplink ports?
A: The 4x SFP+ ports support 1G and 10G transceivers including SFP+ direct-attach copper Twinax cables, multimode and single-mode optical SFP+ modules, and standard Cisco-compatible SFP/SFP+ transceivers for flexible uplink connectivity.

Q: Is this switch suitable for campus or enterprise networks?
A: While the Nexus 3048 can function in enterprise environments, it is primarily designed and optimized for data center top-of-rack deployments with its low-latency architecture, NX-OS software, and data center-focused feature set.
