Chapter 1 Overview
Cisco Nexus 5000 Platform Switches
The Cisco MDS 9200 Series is a part of a family of switches that provide 10-Gigabit Ethernet and FCoE
ports and both 10-Gigabit Ethernet and native 4-, 2-, or 1-Gbps Fibre Channel ports. The switches
provide consolidated I/O connectivity to both production Ethernet LANs and Fibre Channel SANs in a
cost-effective, high-performance, low-latency Ethernet switch.
The Cisco Nexus 5020 switch has the following features:
• Forty fixed 10-Gigabit Ethernet server connection ports on the back of the switch
• Two slots for optional 10-Gbps expansion modules or Fibre Channel interfaces on the back of the
switch
• Two slots on the front of the switch for hot swap-capable power supplies
• Five slots on the front of the switch for hot swap-capable fan modules, each of which houses two
fans, that provide front-to-back (port-side exhaust) cooling for the switch
• The L1/L2/Mgmt1 ports are not usable. They are disabled at this time
Chassis
The Cisco Nexus 5020 chassis is 2 RU (3.47 inches) tall, 17.3 inches wide, and 30.0 inches deep. It is
designed to be mounted in a standard 19-inch rack. The switch has two power supplies and five fan
modules on the front of the switch. Ports are at the rear of the switch. The airflow is front-to-back
(port-side exhaust) so it must be positioned with the front side in a cold isle. Figure 1-27 shows the front
of the Cisco Nexus 5020 switch.
