FAQs

Q: What airflow direction is this model?
A: Rear-to-front (R2F), moving air from the power side to the port side.

Q: Can QSFP+ ports be used as 10G?
A: Yes. With the appropriate breakout cables or optics, each QSFP+ can provide 4x10G.

Q: Are the copper ports PoE-capable?
A: No. The RJ45 interfaces are data-only 1/10GBASE-T.

Q: Do the RJ45 ports support 1GbE?
A: Yes. Ports auto-negotiate 100M/1G/10G depending on link partner and cable quality.

Q: How is multi-switch resiliency achieved?
A: Use MLAG and/or EVPN-based designs rather than traditional chassis stacking.
