FAQs

Q: Can the QSFP28 ports be broken out?
A: Yes. Ports can break out to 4x25G (from 100G) or 4x10G (from 40G) using supported breakout cables or transceivers.

Q: Does the switch support PoE?
A: No. The platform is designed for datacenter switching without PoE.

Q: Which optics are supported?
A: Common QSFP+/QSFP28 modules such as SR4, LR4, CWDM4, and PSM4, as well as DAC/AOC cables, are supported subject to software and hardware compatibility.

Q: What operating system does it run?
A: It runs NX-OS and supports programmatic interfaces such as NX-API.

Q: Are there dedicated uplink ports?
A: No. All 64 QSFP28 ports can be used flexibly as data interfaces.
