What "Tested" Means
Every unit is powered on, run through POST, and checked for:
- All 48 SFP28 and 8 QSFP28 ports verified for link
- Both power supplies and all fans confirmed operational
- Clean EOS boot with no hardware fault codes
- Reset to factory-default configuration
Compatibility
- SFP28 ports: 10GBASE / 25GBASE optics and DAC cables
- QSFP28 ports: 40GBASE / 100GBASE optics and breakout cables
- Ideal for spine-leaf fabrics, high-performance server/storage networks, and low-latency environments
Airflow Note
This is the -F (front-to-rear, port-side exhaust) variant — designed for standard hot-aisle/cold-aisle rack containment. If your rack uses reverse containment, you need the -R variant instead.
