KVM connector
Connect the console breakout cable to this connector (see “Console breakout cable” on page 15
for more information).
Note: It is best practice to connect the console breakout cable to only one compute node at a time in
each Flex System chassis.
USB connector
Connect a USB device to this connector.
Note: It is best practice to connect a USB device to the front of only one compute node at a time in
each Flex System chassis.
Console breakout cable
Use this information for details about the console breakout cable.
Use the console breakout cable to connect external I/O devices to the compute node. The console breakout
cable connects through the KVM connector (see “Compute node controls, connectors, and LEDs” on page
12). The console breakout cable has connectors for a display device (video), two USB connectors for a USB
keyboard and mouse, and a serial interface connector.
The following illustration identifies the connectors and components on the console breakout cable.

Turning on the compute node
Use this information for details about turning on the compute node.
After you connect the compute node to power through the Flex System chassis, the compute node can
be started in any of the following ways:
• You can press the power button on the front of the compute node (see “Compute node controls,
connectors, and LEDs” on page 12) to start the compute node. The power button works only if local
power control is enabled for the compute node. Local power control is enabled and disabled through the
CMM
power command and the CMM web interface.
– For more information about the CMM power command, see the "Flex System
Chassis Management Module: Command-Line Interface Reference Guide" at

power.html.
– From the CMM web interface, select Compute Nodes from the Chassis Management menu.
