Chapter 1 Product Overview
Nexus 5000 Series Switch Hardware
Virtual Interfaces
When FCoE is enabled, a physical Ethernet cable carries traffic for a logical Ethernet connection and a
logical Fibre Channel connection.
The Nexus 5000 Series switch uses virtual interfaces to represent the logical connections that are carried
on the same physical Ethernet. The Nexus 5000 Series switch supports virtual Ethernet and virtual Fibre
Channel interfaces.
For configuration purposes, virtual Ethernet and virtual Fibre Channel interfaces are implemented as
Layer 2 subinterfaces of the physical Ethernet interface.
Link-level features (such as link debounce timer and CDP) are configured on the physical Ethernet
interface. Logical Layer 2 Ethernet features (such as VLAN membership and ACLs) are configured on
the virtual Ethernet interfaces. Logical Fibre Channel features (such as VSAN membership) are
configured on the virtual Fibre Channel interfaces.
Nexus 5000 Series Switch Hardware
The Nexus 5000 Series includes the Nexus 5020 switch. The Nexus 5020 switch hardware is described
in the following topics:
• Chassis, page 1-3
• Expansion Modules, page 1-3
• Ethernet Interfaces, page 1-4
• Fibre Channel Interfaces, page 1-4
• Management Interfaces, page 1-4
Chassis
The Nexus 5020 switch is a 2 RU chassis designed for rack mounting. The chassis supports redundant
fans and power supplies.
The Nexus 5020 switching fabric is low latency, nonblocking and supports Ethernet frame sizes from 64
to 9216 bytes.
Expansion Modules
The Nexus 5020 switch has two slots for optional expansion modules. The following expansion modules
are available:
• N5K-M1404 provides four 10-Gigabit Ethernet ports, and four 1/2/4 Gb Fibre Channel ports.
• N5K-M1600 provides six 10-Gigabit Ethernet ports.
The expansion modules are field-replaceable units (FRUs) that support online insertion and removal
(OIR).
