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 one-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).

Parent Switch Interconnect Are in Front of the Fabric Extenders

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.

Description Specification

Cisco Nexus 2148T 48 1000BASE-T host interfaces and 4 10 Gigabit Ethernet fabric interfaces (Small Form-Factor Pluggable Plus [SFP+])

Cisco Nexus 2224TP 24 100/1000BASE-T host interfaces and 2 10 Gigabit Ethernet fabric interfaces (SFP+)

Cisco Nexus 2248TP 48 100/1000BASE-T host interfaces and 4 10 Gigabit Ethernet fabric interfaces (SFP+)

Cisco Nexus 2232PP 32 1/10 Gigabit Ethernet and Fibre Channel over Ethernet (FCoE) host interfaces (SFP+) and 8 10 Gigabit Ethernet and

FCoE fabric interfaces (SFP+)

The Cisco Nexus 2224TP and 2248TP provide port density options for highly scalable 100-Mbps and Gigabit

Ethernet connectivity. The Cisco Nexus 2232PP provides ease of migration from Gigabit Ethernet to 10 Gigabit

Ethernet while supporting highly scalable 10 Gigabit environments.

The Cisco Nexus 2232PP 1/10GE Fabric Extender is the ideal platform for migration from Gigabit Ethernet to 10

Gigabit Ethernet and unified fabric environments. It supports FCoE and a set of network technologies known

collectively as Data Center Bridging (DCB) that increase the reliability, efficiency, and scalability of Ethernet

networks. These features allow the switches to support multiple traffic classes over a lossless Ethernet fabric, thus

enabling consolidation of LAN, SAN, and cluster environments.

Cisco Nexus 2000 Series Fabric Extenders connect to a parent Cisco Nexus switch through their fabric links using

CX1 copper cable, short-reach or long-reach optics, and the cost-effective Cisco Fabric Extender Transceivers.
