Chapter 6. Module replacement
Overview
Observe all precautions when replacing modules.
Important: Always have available a replacement or blank module before removing the old module.
When you replace a module, you must never leave an empty bay in the rear of the enclosure.
ESD Precautions
Important: Fit and check a suitable anti-static wrist or ankle strap and observe all conventional ESD
precautions when handling plug-in modules and components. Avoid contact with midplane and
sideplane components, and with module connectors.
Continuous operation during replacement
Your hardware or software enclosure management application determines the capability of replacing a
failed disk without loss of access to any file system on the enclosure. Enclosure access and use during
this period is uninterrupted. If an enclosure contains two PSUs, one of them can maintain power to the
system while the other is replaced.
