Subsystem Maintenance
5.1 Overview
5.1.1 About Subsystem Maintenance
Constant monitoring and maintenance of your subsystem will minimize
subsystem downtime and preserve the working integrity of the system for a
longer period of time. If any of the subsystem components fail, they must be
replaced as soon as possible.
WARNING!
Do not remove a failed component from the subsystem until you have a
replacement on hand. If you remove a failed component without
replacing it, the internal airflow will be disrupted and the system will
overheat causing damage to the subsystem.
All of the following components can be replaced in case of failure:
1.
Controller modules –
Section 5.2
2.
Memory module
– Section 5.3
3.
BBU
– Section 5.4
4.
PSU modules –
Section 5.5
5.
Cooling modules (bundled with PSU modules, not separately available)
–
Section 5.6
6.
Hard drives –
Section 5.7
7.
Hard drive trays –
Section 5.7
5.1.2 General Notes on Component Replacement
With the exception of the RAID controller module, all of the
components on the subsystem, including the PSU modules (along with
the cooling modules within), and drive trays, are hot-swappable and can
be replaced while the subsystem is still in operation.
