Power Supply/Blower Assemblies - HP 201723-B21 - StorageWorks Modular SAN Array 1000 Hard Drive Reference Manual

Power Supply/Blower Assemblies

The MSA1000 includes redundant power supply/blower assemblies.
The power supplies share the electrical load equally. If either supply fails or is
removed, the other power supply assumes the full load without interruption.
Hot-pluggability allows you to replace the failed supply without shutting down the
MSA1000 storage system.
The blowers work together to maintain an acceptable operating temperature. If
one blower operates too slowly or completely shuts off, the other blower will
begin to operate at a higher speed.
Any changes in the performance level of the power supply or blower are reported
on the LCD panel of the associated controller. For a description of the possible
informational and error messages associated with the power supplies or blowers,
see the definitions for messages numbered 400 through 499 in the HP
StorageWorks 1000 Modular Smart Array Maintenance and Service Guide.
Depending on the setup of Insight Manager 7 and System Event Analyzer,
informational and error messages about the power supplies and blowers are also
reported though these software components.
Refer to the HP StorageWorks 1000 Modular Smart Array Maintenance and
Service Guide for more information.
