Part Replacement Service Window
The following table contains a time required and a replacement window related to each hot swappable
replacement part within the enclosure. The time required for replacement is the expected amount of time it
requires to replace the part. The replacement window is the amount of time that the enclosure can be open
for servicing. If the enclosure cover is open for a period lasting longer than the replacement window, the
enclosure may reduce access to drives and other components to reduce the occurrence of thermal issues.

part is replaced. Once the enclosure cover is open, the failed fan must be removed within a minute.
The remainder of the replacement of a failed fan should be completed within the 5 minute replacement
windows.
