Supported Transceivers and Cables
The Cisco Nexus 2248TP FEX supports SFP+ Ethernet transceivers. The enhanced Small-Form-Factor
Pluggable (SFP+) 10-Gigabit Ethernet transceiver is a bidirectional device with a transmitter and
receiver. It has a 20-pin connector on the electrical interface and duplex LC connector on the optical
interface. Currently, the Cisco Nexus 2000 Series FEX supports the short-range SFP and long-range SFP
transceiver. Copper interface cables are available for use with the 10-Gigabit Ethernet SFP+ transceiver.
For an updated list of supported transceivers and optics, please see the Cisco Nexus 2000 Series Fabric
Extenders Release Notes.
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 port side exhaust or port side intake air cooling, which makes this
FEX compatible with hot-aisle, cold 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 switch. The FEX software ships with the Cisco Nexus 5500 Series
switch software. The FEX downloads the software image from the switch the same way that a module
would download it from the supervisor in a modular chassis.
