FAQs

Q: Does this switch provide PoE?
A: No. QSFP28 100G ports are data-only and do not supply PoE.

Q: What does front-to-back airflow mean?
A: Air is drawn from the port side (cold aisle) and exhausted toward the power side (hot aisle), aligning with common data center cooling designs.

Q: Can the 100G ports be broken out to 25G?
A: Yes on many platforms via 4x25G breakouts, subject to platform and software support. Consult the device’s port breakout guidelines.
