Dealing with hardware faults

Ensure that you have obtained a replacement module of the same type before removing any faulty

module as described in the Module removal and replacement section.
Important: If the enclosure system is powered up and you remove any module, replace it immediately. If

the system is used with any modules missing for more than a few seconds, the enclosure(s) can overheat,

causing power failure and potential data loss. Such action can invalidate the product warranty.
Important:
Observe applicable/conventional ESD precautions when handling modules and components, as described

in the ESD precautions section. Avoid contact with mid-plane components, module connectors, leads,

pins, and exposed circuitry.

Continuous operation during replacement

ClevOS supports HOT swapping of data disk drives.
If a small disk enclosure is equipped with two or more PCMs, they can maintain power to the system

while a faulty PCM is replaced.
