Frequently Asked Questions

Why does the model say 128 if there are 96 SFP+ ports?

The 128 in the model name refers to the total port count in 10GbE equivalents — 96x 10GbE SFP+ ports plus 8x 40GbE QSFP+ uplinks (each counting as 4x 10GbE) equals 128 total 10GbE equivalent ports.

What does the -F suffix indicate?

The -F suffix indicates front-to-back airflow — air enters from the front and exits from the rear, suitable for cold aisle containment configurations.
