Cisco Nexus 2000 Series Fabric Extenders
The Cisco Nexus 2000 Series Fabric Extenders comprise a category of data center products that provide a universal
server-access platform that scales across a multitude of Gigabit Ethernet, 10 Gigabit Ethernet, unified fabric, rack,
and blade server environments. The Cisco Nexus 2000 Series Fabric Extenders are designed to simplify data center
architecture and operations by meeting the business and application needs of a data center. 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 first product in the Cisco Nexus 2000 Series is the Cisco Nexus 2148T Fabric Extender. The Cisco Nexus 2148T
provides 48 Gigabit Ethernet (1000BASE-T) server ports and four 10 Gigabit Ethernet uplink ports in a compact 1RU
form factor. Designed with architecture to provide the benefits of both top-of-rack and end-of-row configurations, the
Cisco Nexus 2148T offers front-to-back cooling compatible with data center hot-aisle and cold-aisle designs, all
switch ports at the rear of the unit in close proximity to server ports, and all user-serviceable components accessible
from the front panel (Figure 5).

Interfaces for Server Connectivity and Up to Four 10 Gigabit Ethernet Uplink Interfaces
Efficient Transceiver and Cabling Options
The Cisco Nexus 5000 Series supports a wide variety of 10 Gigabit Ethernet connectivity options using Cisco
10GBASE SFP+ modules.
In addition, a subset of the ports on the Cisco Nexus 5020 and 5010 support Gigabit Ethernet connectivity options
using 1GBASE SFP modules, and 4/2/1-Gbps Fibre Channel SFP interfaces are supported with expansion module
options.
