FAQs

Q: Are the 40x SFP/SFP+ ports fixed at 10G?
A: No. Each port flexibly supports 1G or 10G depending on the optic or DAC used.

Q: What are the 40G QSFP+ ports used for?
A: They can be used for 40GbE uplinks to spine/core or for Virtual Chassis/stacking, depending on configuration.

Q: Does this switch support Data Center Bridging?
A: Yes. It includes hardware support for DCB with 802.1Qbb PFC and eight PFC queues.

Q: Can I use third-party SFP+/QSFP+ optics?
A: Standards-compliant optics and DAC/AOC cables are generally supported; verify specific module compatibility before deployment.
