> Most rackmount switches are not really designed to be used in datacenter rack as they do not have front-to-back airflow It's my understanding that switchable fans are standard on cisco, arista, and mellanox switches (have no idea about juniper) and besides, front-to-back or back-to-front depends on whether you mount in the back or in the front (both are valid) AND even if you go the "wrong way" patch panels are pretty easy to find and are cheap (at the expense of 1U)
