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 5.3
5. Cooling modules – Section 5.5
6. Hard drives – Section 5.6.2
