WARNING!
To reduce the risk of personal i njury from hot surfaces, a llow the internal system components to cool
before touching them.
CAUTION:
Do not operate the node for long periods without the access panel. Operating the node without the
access panel results in improper airflow and improper cooling that can lead to thermal damage.

of the following procedures:
• Extend the node from the rack. See Extending the node from the rack.
If you are performing service procedures in an HP, Compaq branded, telco, or third-party rack
