Working in conjunction with Cisco Nexus switches, the Cisco Nexus 2000 Series Fabric Extenders offer a
cost effective and efficient way to support today’s Gigabit Ethernet environments while allowing easy migration to
10 Gigabit Ethernet, virtual machine-aware Cisco unified fabric technologies.
The Cisco Nexus 2000 Series design is aligned with the design of servers. It offers front-to-back or back-to-front
cooling, compatibility with data center hot-aisle and cold-aisle designs, placement of all switch ports at the rear of
the unit in close proximity to server ports, and accessibility of all user-serviceable components from the front
panel. The Cisco Nexus 2000 Series is built for nonstop operation, with redundant hot-swappable power supplies
and a hot-swappable fan tray with redundant fans. Its compact 1RU form factor takes up relatively little space,
making it easy to incorporate into rack designs (Figure 9).
Figure 9. Cisco Nexus 2000 Series Fabric Extenders from Bottom Right to Top Left: Cisco Nexus 2224TP GE, 2248TP GE,
2248TP-E GE, 2232TM 10GE, 2232TM-E 10GE, 2232PP 10GE and 2248 PQ 10GE
The Cisco Nexus 2000 Series provides two types of ports: ports for end-host attachment (host interfaces) and
uplink ports (fabric interfaces). Fabric Interfaces are differentiated with a yellow color for connectivity to the
upstream parent Cisco Nexus switch.
Table 1 lists the Cisco Nexus 2000 Series Fabric Extenders. Fabric extenders can be mixed and matched to a
parent switch to provide connectivity options.
