3.1 Part Replacement Service Window
3.1 Part Replacement Service Window
The following table contains a time required and a replacement window for each hot-swappable
replacement part within the enclosure. The Time Required is the expected amount of time 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.
Table 43: Replacement Service Window
Part Time Required Replacement Window
IOM 1 min 5 min
PSU 1 min 5 min
Rear Fan 1 min 5 min
IOM Fan 1 min 5 min
Drive Assembly 1 min 5 min
Attention: In the case of multiple CRU failures, a failed fan should always be replaced before
any other part. Once the enclosure cover is open, the failed fan must be removed within
a minute. The remainder of the fan replacement should be completed within the 5 minute
window.
3.1.1 Multiple CRU Replacements
This procedure provides information and instructions for replacing multiple CRUs in a single servicing
window.
In order to maintain proper airflow for enclosure cooling, the Ultrastar Data102 can be opened for
servicing of hot-swap components for a maximum of 5 minutes. If multiple CRUs must be replaced within
that servicing window, it is critical to optimize servicing actions to make the best use of that time. The
following procedure describes a scenario where an IOM Fan, an IOM , and a 3.5in HDD Assembly must be
replaced. These instructions provide a strategy for optimizing the servicing window, the order in which
CRUs should be replaced, and how to respond if the replacement time will exceed the overall enclosure
servicing window.
Step 1 : Remotely determine which CRUs have faulted.
Step 2 : Review the appropriate CRU replacement procedures in Support (page 58) to familiarize
yourself with the steps involved, the required parts and tools, and any safety precautions.
Step 3 : Gather all the replacement CRUs and required tools.
