Product overview
Juniper lists QFX5100-48S-3AFO as a 48x10GbE 6x40GbE managed Switch. Airflow direction has to match the rest of the row, and a front-to-back unit dropped into a back-to-front aisle will run hot from day one. Tell us the rack layout and we will confirm the variant.
Ask for the datasheet and firmware notes with the quote; we would rather you check our claim than take it.

Specifying a system, not just the part?
Multi-node training is bounded by the fabric between the nodes, so the switch is specified with the cluster rather than after it.
