IBM Flex System p270 Compute Node Installation And Service Manual page 18

The IBM Flex System p270 Compute Node is a one-bay compute node and is used in an IBM Flex System
Enterprise Chassis.
Notes:
v Power, cooling, removable-media drives, external ports, and Advanced System Management (ASM) are
provided by the IBM Flex System Enterprise Chassis.
v The operating system in the compute node must provide support for the Universal Serial Bus (USB) to
enable the compute node to recognize and communicate internally with the removable-media drives
and front-panel USB ports.
