Supported Transceivers
The Cisco UCS 6300 Series Fabric Interconnects support SFP+ Ethernet transceivers, SFP transceivers, SFP+
transceivers, SFP+ copper twinax cables with integrated transceivers, SFP Fibre Channel transceivers, QSFP
transceivers, and QSFP cables. Except where noted, both the UCS 6332 Fabric Interconnect and the UCS
6332-16UP Fabric Interconnect support all the transceivers listed in this section.
On the Cisco UCS 6332 Fabric Interconnect, all 1-Gigabit and 10-Gigabit transceivers and twinax cables
must use a QSA module (CVR-QSFP-SFP10G) to operate in a 40-Gbps QSFP+ port. In addition, the QSA
module is required for a 40-Gbps QSFP+ port to operate at 1 Gbps or 10 Gbps.
On the Cisco UCS 6332-16UP Fabric Interconnect, all 1-Gigabit and 10-Gigabit transceivers, Fibre Channel
transceivers, and twinax cables must use a QSA module (CVR-QSFP-SFP10G) to operate in ports 17–40 (the
40-Gbps QSFP+ ports). Ports 1–16 operate as SFP+ universal ports that are capable of operating at 1- or
10-Gbps fixed Ethernet or 4-, 8-, or 16-Gbps Fibre Channel ports and do not need a QSFP to SFP+ adapter.
In addition, the QSA module is required for a 40-Gbps QSFP+ port to operate at 1 Gbps or 10 Gbps.
SFP 1-Gigabit Transceivers
The SFP 1-Gigabit Ethernet transceiver module is a bidirectional device with a transmitter and receiver in the
same physical package.
