The Cisco Nexus 3548P-10GX (N3K-C3548P-10GX) is 1 rack unit (RU) switch with 48 fixed 1- and 10-Gigabit Ethernet small form-factor pluggable (SFP+) ports, 1 fixed 10/100/1000 management port, 1 console port, and 2 USB ports. This switch supports both port-side exhaust and port-side intake airflow schemes. It requires one AC or DC power supply for operations, but it can have a second power supply for redundancy.
