About Subsystem Maintenance
Constant monitoring and maintenance of your subsystem minimizes
system downtime and preserves the working integrity of the system
for a longer period of time. If any of the components fails, 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 modules –
Section 5.2
2. Memory modules –

3. BBUs

Section 5.4
4. PSUs
