Replacing a ZS5-2 DIMM

Removing a DIMM is a cold-service operation. You must power off the appliance before you remove the DIMM. There will be a loss of access to the storage unless the system is in a clustered configuration.

1. Identify the faulted DIMM.

   Go to the Maintenance > Hardware section of the BUI, click the right-arrow icon for the controller, click DIMM, and note the ID of the faulted DIMM, which has an amber icon. To highlight the location of the memory module in the controller picture, click on the module ID. To view details about the faulted module, click its information icon and then click Active Problems.

2. Shut down the controller using one of the power-off methods described in Powering Off the Controller.
3. Disconnect the AC power cords from the rear panel of the storage controller.

   Caution  -  Because 3.3 VDC standby power is always present in the system, you must unplug the power cords before accessing any cold-serviceable components.
