Transceivers and Connectors Supported by the Cisco Nexus 2248TP FEX
The Cisco Nexus 2248TP FEX supports SFP+ Ethernet optical and copper transceivers and optical FEX
Transceivers (FETs) for up to four fabric uplink connections to Cisco Nexus 7000 Series switches, and
it supports RJ-45 connectors for up to 48 downlink connections to hosts. For each uplink cable, you must
use the same transceiver on both ends.
Table 2-2
lists the transceivers supported by this FEX for its
uplink fabric .
Figure 2-10 on page 2-10
shows the SFP+ optical transceiver used for uplink connections. For
specifications that apply to these optical transceivers, see the
“SFP+ Optical Transceiver Specifications”
section on page B-6
