Information About Using a Fabric Extender with a Cisco Nexus
5000 Series Switch
The Cisco Nexus 2000 Series Fabric Extenders (FEXs) support Gigabit Ethernet and 10-Gigabit Ethernet
environments while allowing transparent migration to 10-Gigabit Ethernet virtual machine aware unified
fabric technologies. The Cisco Nexus 2000 Series FEXs behave as remote I/O modules for a parent Cisco
Nexus 5000 Series switch. The FEX is an extension of the parent Cisco Nexus switch fabric, with the
FEX and the parent Cisco Nexus switch together forming a virtual modular system.
A Cisco Nexus 2000 Series FEX forwards all the traffic to the parent Cisco Nexus 5000 Switch over
10-Gigabit Ethernet uplinks. Passing all traffic to the parent switch allows traffic to be shaped according
to policies established on the parent Cisco Nexus 5000 Series switch with a single point of management.
Cisco Nexus 2248TP-E
The Cisco Nexus 2248TP-E is a stackable 1 RU 17.2-inch (45 cm) deep FEX that supports 48 1000-TX
host-facing (downlink) ports and 4 10-Gigabit SFP+ network-facing (uplink) ports. You can order it with
front-to-back or back-to-front air cooling, and with AC or DC power supplies.
