SFP+ Copper Cables
Copper interface cables are available for use with the 10-Gigabit Ethernet SFP+ transceiver. Table 1- 8
lists the available cables and provide s a brief description of the ca bles.
Cisco Nexus 2248PQ
The Cisco Nexus 2248PQ is a stackable 1 RU 17.2 inch (45 cm) deep FEX that supports high-density
10-Gigabit Ethernet environments and has 48 1/10-Gigabit SFP+ host interfaces and 4 QSFP+ (16
10-Gigabit ) on network interfaces. QSFP+ connectivity simplifies cabling while lowering power and
solution costs. You can order it with front-to-back or back-to-front air cooling, which makes this FEX
compatible with hot-aisle, col d aisle data center designs.
You can use this FEX with the Cisco Nexus 5500 Series switch and the Cisco Nexus 6004 parent switch
(The supported software is Cisco Nexus OS Release 6.0(2)N1(1) ). The Cisco Nexus 2248PQ is managed
and configured by the upstream swit ch. The FEX software ships wit h the Cisco Nexus 5500 Series
switch software. The FEX download s the software image from the sw itch the same way that a module
would download it from the supervisor in a modular chassis.

Chassis
The Cisco Nexus 224 8PQ FEX chassis has a height of 1.72 inc hes (4.37 cm), a widt h of 17.3 inches
(43.94 cm), and a depth of 17.7 inches (44.96 cm). It weighs 17.5 pounds (8.0 kg). Its one-rack-unit (1
RU) form factor takes up relatively little space, ma king it easy to incorporate into rack designs. The FEX
is mounted in a standard 19-inch (48.26 cm) rack. All of the switch ports at the rear of the chassis are in
close proximity to server ports, and all user-serviceable components are accessible from the front panel.
