CAUTION:
You have only seven minutes to perform the replacement procedure! Both power supplies must be
installed for the enclosure to co ol properly. If a power supply fails, leave it in place in the enclosure until
a new power supply is available to install. The enclosure could shut down due to overheating unless the
power supply is replaced within seven minutes of removal of the failed/failing power supply.
If cabling is obstructing access to the power supply/blower, c arefully move the cables out of the way
to avoid loosening any connections.
Parts can be damaged by electrostatic discharge. Use proper anti-static protection. Refer to the
documentation that shipped with your system for additional information.
Have a copy of the product User Guide available for reference. You can download a copy of the User
Guide from the product support page on the HP web site.
