Console Breakout Cable - Lenovo Flex System x480 X6 Compute Node Installation And Service Manual

After the compute node is removed from the chassis, press and hold this button to activate the
system-board LEDs (light path diagnostics). See "Compute node controls, connectors, and LEDs" on
page 14 for more information.
This button is also the power LED. This green LED indicates the power status of the compute node:
• Flashing rapidly: The LED flashes rapidly for one of the following reasons:
– The compute node has been installed in a chassis. When you install the compute node, the LED
flashes rapidly for up to 90 seconds while the integrated management module II (IMM2) in the
compute node is initializing and synchronizing with the chassis management module.
– Power permissions have not been assigned to the compute node through the Chassis
Management Module.
– The Lenovo Flex System chassis does not have enough power to turn on the compute node.
– The IMM2 in the compute node is not communicating with the Chassis Management Module.
• Flashing slowly: The compute node is connected to power through the Lenovo Flex System chassis
and is ready to be turned on.
• Lit continuously: The compute node is connected to power through the Lenovo Flex System chassis
and is turned on.
When the compute node is on, pressing this button causes an orderly shutdown of the compute node
so that it can be removed safely from the chassis. This includes shutting down the operating system (if
possible) and removing power from the compute node.
If an operating system is running, you might have to press the button for approximately 4 seconds to
initiate the shutdown.
Pressing the button for 4 seconds forces the operating system to shut down immediately. Data loss
is possible.
KVM connector
Connect the console breakout cable to this connector (see "Console breakout cable" on page 17
for more information).
Note: It is best practice to connect the console breakout cable to only one compute node at a time
in each Lenovo 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 Lenovo Flex System chassis.

Console breakout cable

Use this information for details about the console breakout cable.
Use only the console breakout cable that comes with the compute node. Attempting to connect other
console breakout cable types might damage the console breakout cable and the compute node.
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
14). 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.
