Technical Specifications

FAQs

Q: Are the 10GBASE-T ports backward compatible with 1GbE?
A: Yes. They auto-negotiate 100M/1G/10G based on link partner and cabling.

Q: Can the QSFP+ ports be split into 10G lanes?
A: Yes. Each QSFP+ can break out to 4x10G with supported DAC/AOC or optics.

Q: Does this switch support stacking?
A: It does not use traditional stacking; use MLAG and/or EVPN-based designs for multi-switch resiliency.

Q: Is PoE supported on the copper ports?
A: No. The RJ45 ports are data-only 1/10GBASE-T.

Q: Which optics are supported on the QSFP+ uplinks?
A: Common 40G QSFP+ options include SR4 and LR4, plus passive/active DAC and AOC cables; 4x10G breakout is also supported.

Q: What airflow direction is this model?
A: Front-to-rear (F2R), suitable for cold-aisle front installations.
