Chapter 1 Cisco Nexus 5500 Platform Overview Applications Send documentation comments to nx5000-docfeedback@cisco.com • Energy efficiency that helps data centers operate within their space, power, and cooling parameters while reducing their carbon footprints. Every network link at the rack level requires adapters, switches, and transceivers, all of which consume power. I/O consolidation reduces energy consumption by eliminating the need for separate Fibre Channel adapters, cables, and switches.
Chapter 1 Cisco Nexus 5500 Platform Overview Cisco Nexus 5548P Switch Send documentation comments to nx5000-docfeedback@cisco.com Features The Cisco Nexus 5548P switch is the first switch in the Cisco Nexus 5500 Platform. It is a one-rack-unit (1 RU), 10-Gigabit Ethernet and FCoE switch that offers up to 960-Gbps throughput and up to 48 ports. The switch has 32, 1- or 10-Gbps fixed small form-factor pluggable plus (SFP+) Ethernet and FCoE ports and one expansion slot.
