Transceivers and Connectors Supported by the Cisco Nexus 2248TP-E FEX
The Cisco Nexus 2248TP-E 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 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.
