Cisco Nexus 5548P Overview
The Cisco Nexus 5548P is a one-rack-unit (1RU), 1 and 10 Gigabit Ethernet and FCoE access-layer switch built to provide 960 Gbps of throughput with very low latency. It has 32 fixed 1 and 10 Gigabit Ethernet ports that accept modules and cables meeting the Small Form-Factor Pluggable Plus (SFP+) form factor. One expansion module slot can be configured to support up to 16 additional 1 and 10 Gigabit Ethernet ports or 8 Fibre Channel ports plus 8 1 and 10 Gigabit Ethernet ports. The switch has a single serial console port and a single out-of-band 10/100/1000-Mbps Ethernet management port. Two N+N redundant, hot-pluggable power supplies and two N+N redundant, hot-pluggable fan modules provide highly reliable front-to-back cooling.
All ports are at the rear of the switches, simplifying cabling and reducing cable length (Figure 2). Cooling is front-to-back, supporting hot- and cold-aisle configurations that help increase cooling efficiency. The front panel (Figure 3) includes status indicators and hot swappable, N+N redundant power supplies and their power entry connections and cooling modules. All serviceable components are accessible from the front panel, allowing the switch to be serviced while in operation and without disturbing network cabling.
