The Cis Nexus 5010 is a 1RU, 10 Gigabit Ethernet, FCoE, and Fiber Channel switch providing more than 520-Gbps throughput with very low latency. It has 20 fixed 10 Gigabit Ethernet and FCoE SFP+ ports. The first 8 fixed ports are dual speed, supporting both 10 Gigabit Ethernet and Gigabit Ethernet in hardware and providing a smooth migration path to 10 Gigabit Ethernet. One expansion module slot can be configured to support up to 6 additional 10 Gigabit Ethernet and FCoE SFP+ ports, up to 8 4Gbps SFP Fiber Channel switch ports, up to 6 8Gbps SFP+ Fiber Channel switch ports or a combination of 4 additional 10 Gigabit Ethernet and FCoE SFP+ ports with 4 additional 4/2/1-Gbps Fiber Channel switch ports. The switch has a serial console port and an out-of-band 10/100/1000-Mbps Ethernet management port. The switch is powered by 1+1 redundant, hot-pluggable power supplies and 1+1 redundant, hot-pluggable fan modules to provide highly reliable front-to-back cooling.
