I2C read port information comes from SFP28 port module, not QSA Module.
- 【Smooth Speed Migration】10Gtek QSA adapter Module offers 25 Gigabit Ethernet connectivity for QSFP28-only platforms. It allows smooth and cost-effective migration to 100 Gigabit Ethernet by providing an option to use lower-speed.
- 【Convenient and Flexible Use】With QSA adapter, you can flexibly use any SFP28 module or cable to connect to a lower-speed port on the other end of the network with low insertion loss and crosstalk. Plug and play, without any setup.[Note: This module can only reach 10G rate when used on Mellanox equipment, not 25G.]
