System Maintenance

5.1 Overview

5.1.1 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 subsystem 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:

RAID controller modules –

Section 5.2

Memory modules –

Section 5.3

BBU –

Section 5.4

PSUs –

Section 5.5

Cooling modules –
