The Cisco Nexus® 3636C-R switch is a high-speed, high-density 10-, 25-, 40-, or 100-Gigabit Ethernet (GE) switch designed for the data center spine. The large buffers and routing table sizes of the 3636C-R also make this switch an alternative for a wide range of applications, such as IP storage, demilitarized zone (DMZ), big data, and edge routing. The switch comes in a compact 1-Rack-Unit (1RU) form factor and provides extensive Layer 2 and Layer 3 functions. It is part of the R-Series family and runs industry-leading Cisco® NX-OS Software.

The comprehensive programmability features enable organizations to run today's applications while also preparing them for demanding and changing application needs. The Cisco Nexus 3636C-R switch supports both forward and reverse (port-side exhaust and port-side intake) airflow schemes with AC and DC power inputs.

The 3636C-R is a Quad Small Form-Factor Pluggable (QSFP) switch with 36 QSFP28 ports. Each QSFP28 can operate at 100 or 40 Gigabit Ethernet or in a breakout cable configuration.
