The 7133 can be disconnected from its related SSA attachments while the using system
is running. Also, most of the field-replaceable units (FRUs) of the 7133 can be removed
and replaced while the 7133 and the using system are running. For a list of those
FRUs, see “Concurrent Maintenance” on page 137.
Each 7133 Model D40 or Model T40 contains two power supply assemblies and three
fan assemblies, which together provide all the necessary power and cooling. It also
contains a controller card, which monitors and controls the various functions of the
7133. For further details about the controller card, see “Controller Card” on page 3.
The 7133 Models D40 and T40 can be configured to the using system as devices if
applicable. See “Configuring a 7133 to the Using System” in the “Additional Information”
appendix (in this book) for your using system. When a 7133 is configured as a device:
v
Errors that are detected in the 7133 are logged in the system error log against that
7133.
v
Vital product data (VPD) for the 7133 can be accessed.
Each FRU contains its own VPD. A using system can access this VPD while the 7133
is being configured to that particular using system.
Enclosure configuration information is stored in several locations in the 7133 to allow
concurrent replacement of FRUs. (Such information might be, for example, the
information that is displayed on the ID display of the 7133.) When a new FRU is
installed, any special configuration information that is required by that FRU is read from
other locations in the 7133. That information is then used to update the new FRU. To
ensure that the configuration is not corrupted or changed, always exchange FRUs one
at a time. Do not exchange multiple FRUs between 7133s.
