Replacing SCv2000/SCv2020 Storage System Components 2 This section describes how to remove and install components of the SCv2000/SCv2020 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.
• Provide a suitable power source with electrical overload protection. All Storage Center components must be grounded before applying power. Make sure that there is a safe electrical earth connection to power supply cords. Check the grounding before applying power. • The plugs on the power supply cords are used as the main disconnect device. Make sure that the socket outlets are located near the equipment and are easily accessible.
NOTE: To ensure proper storage system cooling, hard drive blanks must be installed in any hard drive slot that is not occupied. Pre-Replacement Procedures Perform the procedures described in this section before replacing a component of the SCv2000/ SCv2020 storage system. Send Diagnostic Data Using Dell SupportAssist Use Dell SupportAssist to send diagnostic data to Dell Technical Support Services. 1. Use the Storage Client to connect to the Storage Center. 2.
Shutting Down the Storage System If you are replacing the storage system chassis or rack rails, use the Dell Storage Client to shut down the storage system. About this task CAUTION: Shutting down the storage system results in a system outage. Steps 1. Select Actions → System → Shutdown/Restart. The Shutdown/Restart dialog box appears. 2. Select Shutdown Controller from the first drop-down menu. 3. Click OK.
Replacing Power Supply/Cooling Fan Modules The SCv2000/SCv2020 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. If one power supply/cooling fan module fails, the second module continues to provide power to the storage system.
Figure 11. Rear View of the Enclosure Showing the Failed Power Supply Identifying the Failed Cooling Fan To determine which cooling fan failed, use the Dell Storage Client. 1. Click the Hardware tab. 2. In the Hardware tab navigation pane, select and expand the failed storage system. 3. In the Hardware Alerts area, find the hardware alert that identifies the enclosure with the failed cooling fan.
Figure 12. Hardware Alert Identifying the Enclosure with the Failed Cooling Fan 4. In the Hardware tab navigation pane, expand the enclosure identified in the previous step. 5. Select Cooling Fan Sensors. The status of each cooling fan is displayed in the Cooling Fans tab. 6. Select the failed cooling fan. The location of the failed cooling fan is displayed in the Fan View tab. Figure 13.
Replacing a Power Supply/Cooling Fan Module Use this procedure to replace a failed power supply/cooling fan module. Prerequisites • Use SupportAssist to send diagnostic data to Dell Technical Support Services. About this task You can replace power supply/cooling fan modules one at a time without shutting down the storage system. Steps 1. Press the power switch on the power supply/cooling fan module to turn it off. 2.
Figure 15. Securing the Power Cable 6. Press the power switch on the power supply/cooling fan module to turn it on. NOTE: Allow several seconds for the storage system to recognize the power supply/cooling fan module and determine its status. When the power supply/cooling fan module is functioning properly, the AC power status indicator turns green and the three fault indicators are off. 7.
Figure 17. SCv2020 Storage System Drive Numbering Identifying the Failed Hard Drive To determine which hard drive failed, use the Dell Storage Client. 1. Start the Dell Storage Client and connect to the Storage Center that has an expansion enclosure with a failed hard drive. 2. Click the Hardware tab. 3. In the Hardware tab navigation pane, select and expand the Storage Center. 4. In the Hardware Alerts area, find the hardware alert that identifies the expansion enclosure with the failed hard drive.
Figure 19. Front View of the Expansion Enclosure Showing the Failed Hard Drive 8. (Optional) To open a wizard to guide you through the replacement steps, right-click on the failed hard drive. Replacing a Hard Drive Use this procedure to replace a failed hard drive. About this task Hard drives can be replaced one at a time without shutting down the storage system. NOTE: At least one powered drive must remain installed in the primary chassis when multiple disks are replaced. Steps 1.

Slide the battery into the storage controller until the release tab clicks into place. Next steps Use SupportAssist to send diagnostic data to Dell Technical Support Services. Replacing a Storage Controller The SCv2000/SCv2020 storage system supports redundant hot-swappable storage controllers.
Figure 23. Hardware Alert Identifying the Enclosure with the Failed Storage Controller 4. In the Hardware tab navigation pane, expand the Enclosures entry. 5. Click I/O Modules. The status of each storage controller is displayed in the I/O Modules tab. 6. Select the failed storage controller to display its location in the IO Module View tab. Figure 24.
Replace a Single Storage Controller Use this procedure to replace a single failed storage controller. Prerequisites 1. Use SupportAssist to send diagnostic data to Dell Technical Support Services. 2. Shut down the storage controller using the Dell Storage Client. About this task Storage controllers can be replaced one at a time without shutting down the storage system. Steps 1. Make sure all of the cables are labeled. 2. Disconnect all of the cables from the storage controller that was shut down. 3.
10. Push the release lever toward the chassis until it clicks into place. The storage controller is powered on. NOTE: When a storage controller is powered on, a one‐minute delay occurs while the storage controller prepares to boot. During this time, the only indication that the storage controller is powered on are the LEDs on the storage controller. After the one‐minute delay, the fans and LEDs turn on to indicate that the storage controller is starting up. 11.
