Voltages are present at various locations within the server whenever an AC power
source is connected. This voltage is present even when the main power switch is in
the off position.
Failure to observe this warning could result in personal injury or damage to
equipment.
CAUTION Do not operate the HP server for more than 5 minutes with any cover (including disk drives)
removed. If you are hot-swapping a fan, reinstall the cover within 5 minutes to prevent
overheating. Damage to system components may result due to improper cooling airflow.
To troubleshoot your server with online diagnostic tools, you must be familiar with the HP-UX operating
system. You should also be familiar with the Offline Diagnostics Environment (ODE). Install both online and
offline troubleshooting programs on your system before trouble is suspected. Descriptions and user
information about offline troubleshooting tools are available at http://docs.hp.com.
Use the online diagnostic tools if you can boot your system. Online troubleshooting programs area available
on the HP-UX operating system CD.
If you can not boot your system, run offline troubleshooting tool from the ODE CD that ships with your
server. ODE CDs are platform-specific for Integrity and PA-RISC servers.
