T5 Adapters
Chelsio T5 40G adapters can be configured in the following 3 modes:
i. 2X40Gbps: This is the default mode of operation where each port functions as 40Gbps link.
The port nearest to the motherboard will appear as the first network interface (Port 0).
ii. 4X10Gbps (Spider): In this mode, port 0 functions as 4 10Gbps links and port 1 is disabled.
iii. QSA: This mode adds support for QSA (QSFP to SFP+) modules, enabling smooth, cost-
effective, connections between 40 Gigabit Ethernet adapters and 1 or 10 Gigabit Ethernet
networks using existing SFP+ based cabling. The port farthest from the motherboard will
appear as the first network interface (Port 0).
