 2000 Series Fabric Extenders (FEX) behave as remote line cards 
for a parent Cisco Nexus 5000 Series or 7000 Series switch, simplifying data center 
access operations and architecture by combining the management simplicity of 
end-of-row platforms with the flexible physical layout of top-of-rack platforms.
•  Up to 48 100/1000 BASE-T ports plus 4 10 GE uplinks, 32 1/10 GE/FCoE with 8 10 
GE uplinks and 32 1/10GBASE-T with 8 10 GE uplinks configurations
•  Up to 24 Fabric Extenders per Cisco Nexus 5000 parent switch (Homogeneous 
policies across 1152 1G ports and 768 10G/FCoE ports)
•  Up to 32 Fabric Extenders per Cisco Nexus 7000 parent switch (Homogeneous 
policies across 1536 1G ports and 1024 10G ports)
•  Rich Layer 2-4 switching features and intelligent services inherited from  
parent switch
•  Ideal to support today's traditional Gigabit Ethernet while allowing transparent 
migration to 10 Gigabit Ethernet, virtual machine-aware, unified fabric technologies
•  Operational simplicity at scale for datacenter point of delivery (POD) access  
level design
•  Front-to-back cooling compatible with data center hot-aisle and cold-aisle design, 
forward and reversed airflow options, AC/DC power supply options

Blade Switches
Cisco Nexus 4000 Series
The Cisco Nexus™ 4001I Switch Module for IBM BladeCenter is a blade 
switch solution for IBM BladeCenter H and HT chassis, providing the server 
I/O solution required for high-performance, scale-out, virtualized and 
non-virtualized x86 computing architectures.
•  Line-rate, extremely low-latency, nonblocking, Layer 2, 10 Gigabit Ethernet 
blade switch
•  Fully compliant with the INCITS Fibre Channel over Ethernet (FCoE) and IEEE 
802.1 Data Center Bridging (DCB) standards
•  Unified Fabric architecture provides a significant reduction in the number of 
switches, network interface cards, cabling, and power requirements.
•  Supports 14 fixed 1 or 10 Gigabit Ethernet server-facing downlinks and 6 
fixed 1 or 10 Gigabit Ethernet uplinks
