Supported Transceivers and Cables
The Cisco Nexus 2248TP-E 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 2248TP-E 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 details see, the
Cisco Nexus 2000 Series Fabric Extenders Release Notes.
Cisco Nexus 2248TP
The Cisco Nexus 2248TP is a stackable 1 RU 17.2-inch (45 cm) deep FEX that supports 48 1000-TX
host-facing (downlink) ports and 4 10-Gigabit SFP+ network-facing (uplink) ports. You can order it with
port side exhaust or port side intake air cooling, and with AC or DC power supplies.
You can use this FEX with the Cisco Nexus 5000 Series switch. The Cisco Nexus 2248TP is managed
and configured by the upstream switch. The FEX software ships with the Cisco Nexus 5000 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.
