Compaq StorageWorks RAID Array 4000 User Guide
Be careful when working around the power and Fibre Channel
cables on the back of a working RA4000. Accidentally disconnecting a cable
could cause loss of data.
Do not operate the RA4000 for extended periods of time with either
power supply location open. Internal cooling air flow will be disrupted without a
power supply or blanking panel installed in both locations. This could cause
overheating of internal components and possible data loss. In Redundant Power
Supply systems, retain the blank power supply cover in case it is necessary to
remove one of the supplies again in the future.
Perform the following steps to install the Redundant Power Supply option in
the Compaq RA4000.
1. Loosen the thumbscrew securing the blanking panel over the lower
power supply opening and remove the panel.
