Warnings and Cautions
Before removing the node access panel, be sure that you understand the following warnings and
cautions.
WARNING!
To reduce the risk of electric shock or damage to the equipment:
• Do not disable the AC power cord grounding plug. The grounding plug is an important safety
feature.
• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all times.
• Unplug the power cord from each power supply to disconnect power to the equipment.
WARNING!
To reduce the risk of personal injury from hot surfaces, allow the drives and 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.
Preparation Procedures
To access some components and perform certain replacement procedures, you must perform one or
more 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
cabinet, use the locking feature of the rack rails to support the node and gain access to internal
components.
For more information about telco rack solutions, see the RackSolutions.com web site (

• If you must remove a non-hot-plug component from the node, power off the system. See Powering
Off the System .
• Remove the node from the rack. See Removing the Node from the Rack .
• Remove the node access panel. See Removing the VLS Node Access Panel .
If you must remove a component located inside the node, remove the access panel.
