4.1 Replaceable components
Your EonStor DS system is comprised of replaceable components:
• PSU module
• Hard disk drives
WARNING!
• DO NOT remove a defective component from the system until you have the replacement on hand.
Doing so may disrupt the internal airow.
• Consult with the qualied engineers who are familiar with the system to recommend component
replacements.
• DO NOT use excessive force when installing a replaceable module. Forced installation of the
module can damage the connector pins of the system, the module, or the internal backplane.

The PSUs are congured in a redundant conguration, with each PSU housed in a robust steel canister.
