Subsystem Maintenance
5.1. Introducing Subsystem Maintenance and
Upgrading
5.1.1 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. RAID controller module – Section 5.2.3
2. DIMM module – Section 5.2.4
3. BBU module – Section 5.3
4. PSU modules – Section 5.4
5. Cooling modules – Section 5.5
6. Hard drives – Section 5.6.2
