●
Highly scalable server access: Gigabit and 10 Gigabit Ethernet server access is scalable, with no reliance
on Spanning Tree Protocol.
●
Simplified operations: One single point of management and policy enforcement using upstream Cisco
Nexus switches eases the commissioning and decommissioning of server racks through zero-touch
installation and automatic configuration of fabric extenders.
●
Increased business benefits: Consolidation, cabling reduction, rack-space reduction, reduced power and
cooling, investment protection through feature inheritance from the parent switch, and the capability to add
functions without the need for a major equipment upgrade of server-attached infrastructure all contribute to
reduced operating expenses (OpEx) and capital expenditures (CapEx).
The Cisco Nexus 2000 Series design aligns with that of servers. It 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. It also offers back-to-front cooling,
with switch ports in front of the chassis, aligned with the cold aisle, for optimized cabling in network racks. 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 1-rack-unit (1RU) form factor takes up relatively little space,
making it easy to incorporate into rack designs. The fabric extenders are available in several models to provide
speed, connectivity, and port-density options (Figure 2).

The Cisco Nexus 2000 Series provides two types of ports: ports for end-host attachment (host interfaces) and
uplink ports (fabric interfaces). Fabric interfaces, differentiated with a yellow color, are 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.
