Replacing System Components

Notice: Do not remove or service any I/O modules, storage modules, or compute modules if the ztC Endurance console​ is reporting any PSU faults.

You must first restore full PSU functionality to both PSUs before removing any other modules for additional service (that is, the LED on both PSUs must be solid green).

In extreme circumstances, failure to follow this service sequence may result in compromised power integrity to the ztC Endurance system.

Before replacing a system component, do the following:

  • Confirm that the component has failed and needs to be replaced. You can view failure information from the status LEDs on each component, from your system’s event or error logs, and from viewing the Dashboard page of the ztC Endurance console​.

  • Determine if a component needs to be taken out of service.

  • Observe the proper safety precautions by following the precautions listed in General Safety Precautions.

After replacing a component, do the following:

  1. Place the component in service if it is out of service.

  2. Verify system operation.

  3. Package and ship the failed component. See Repacking System Components.
