2 Replacing Storage System Components This chapter describes how to remove and install components of the SC5020 series storage system. This information assumes that you have received the replacement component and are ready to install it. Safety Precautions Always follow these safety precautions to avoid injury and damage to Storage Center equipment. If equipment described in this guide is used in a manner not specified by Dell, the protection provided by the equipment could be impaired.
Electrostatic Discharge Precautions Always follow electrostatic discharge (ESD) precautions to avoid injury and damage to Storage Center equipment. Electrostatic discharge (ESD) is generated by two objects with different electrical charges coming into contact with each other. The resulting electrical discharge can damage electronic components and printed circuit boards.

Power Supply and Cooling Fan Modules The SC5020 series storage system supports two hot-swappable power supply/cooling fan modules. The cooling fans that cool the storage system and the power supplies are integrated into the power supply/cooling fan module and cannot be replaced separately.
Figure 8. Removing the Hook and Loop Strap from the Power Cable 3 Push the release tab on the power supply/cooling fan module to the right and use the handle to slide the module out of the chassis. CAUTION: The power supply/cooling fan modules are heavy. To avoid injury, use both hands while removing the module. Figure 9.
Next step 1 Use Dell Storage Manager to edit the Storage Center settings and set the operation mode of the Storage Center to Production mode. 2 Use Dell Storage Manager to send SupportAssist information to technical support. Storage Controllers Use this procedure to remove a storage controller from the chassis. Remove a storage controller if it fails or if a component inside the storage controller fails.
Figure 10. Installing the Service Baffle Storage Controller Each storage controller contains the front-end, back-end, and management communication ports of the storage system. Remove a Storage Controller Use this procedure to remove a storage controller from the chassis. Prerequisites 1 Locate the storage controller service baffle. CAUTION: To prevent a thermal shutdown of the storage system, the service baffle must be installed within three minutes of removing the storage controller.
Figure 11. Removing and Installing a Storage Controller 8 1 SC5020 series storage system chassis 3 Release lever 2 Storage controller Install the service baffle into the empty slot in the storage system chassis. Install a Storage Controller Install the storage controller into the storage system chassis. About this task The cover of the storage controller indicates which slot the storage controller operates in. • Storage controller 1 goes into the top slot.
Next steps 1 Use Dell Storage Manager to send SupportAssist information to technical support. 2 Contact technical support to let them know that you have completed a repair. Replace a Failed Storage Controller Replace a failed storage controller with a replacement storage controller. Prerequisite CAUTION: Do not power down both storage controllers. The other storage controller continues to operate when the failed storage controller is powered down.
Next steps 1 Use Dell Storage Manager to edit the Storage Center settings and set the operation mode of the Storage Center to Production mode. 2 Use Dell Storage Manager to send SupportAssist information to technical support Storage Controller Cover The storage controller cover protects the internal components of the storage controller. Remove the Storage Controller Cover Remove the cover of the storage controller to access the components inside.
Replace the Storage Controller Cover Replace the cover of the storage controller before reinserting it into the storage system chassis. 1 Place the cover on top of the storage controller. 2 Slide the cover towards the back of the storage controller until it locks in place.. CAUTION: Do not operate the storage controller without the cover. Figure 13.
• Use Dell Storage Manager to edit the Storage Center settings and set the operation mode of the Storage Center to Maintenance mode. Steps 1 Shut down the storage controller using Dell Storage Manager. 2 Make sure that all cables plugged into the storage controller are labeled. 3 Disconnect the cables from the storage controller that was shut down.
