3.7 System Nodes
The chassis includes power supplies, rear I/O ports, expansion card slots and four nodes.
Each node is a separate system containing a drawer with a motherboard, fans, and other
components and may be removed from the chassis separately.
Each node in the system supports six 3.5" drive bays. Two M.2 NVMe slots are also supported.
For compatible storage drives, see the
The drives are mounted in toolless drive carriers that simplify their removal from the chassis.
These carriers also help promote proper airflow.
Note:
Enterprise level hard disk drives are recommended for use in Supermicro chassis and
servers. For information on recommended HDDs, visit the Supermicro website product pages

Installing and Removing the Node Drawers
The F620P3-RTBN contains four individual motherboards in separate node drawers. Note
that if a node drawer is pulled out of the chassis, the hard drives associated with that node
will power down as well.
Warning
: Except for short periods of time, do not operate the server without the cover in place.
The chassis cover must be in place to allow for proper airflow and to prevent overheating.
