Replacing the Enclosure
The RAID enclosures are ruggedly constructed and under extremely rare instances
do they incur damages so severe (breakage causing circuit exposure, deformation,
etc.) that require replacing the enclosure. However impossible it may be, the
likely-hood of an enclosure needing to be replaced is usually due to a faulty
integrated backplane that separates the front and rear sections of the chassis as
mentioned previously in section
. The internal backplane contains
a circuit board that provides logic level signals and low voltage power paths. Thermal
sensors and I
2
C devices are embedded to detect system temperatures and
PSU/cooling module operating status. And as this board contains no
user-serviceable components, when damaged, you will have to replace the entire
enclosure
A faulty backplane board may cause the following:
Falsely report module statuses
Unable to power on some modules or not able to power on the system at all
System
instability
Poor
system
performance
Affect storage data integrity
