Replacing SC100/SC120 Expansion Enclosure Components 2 This section describes how to remove and install components of the SC100/SC120 expansion enclosure. 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 expansion enclosure 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 SC100/SC120 expansion enclosure. Send Diagnostic Data Using Dell SupportAssist Use Dell SupportAssist to send diagnostic data to Dell Technical Support. 1. Use the Storage Client to connect to the Storage Center. 2.
Replacing the Front Bezel The front bezel is a cover for the front panel of the expansion enclosure. About this task The front bezel must be removed from the front panel when replacing hard drives. Steps 1. Use the system key to unlock the keylock at the left end of the bezel. 2. Lift the release latch next to the keylock. 3. Rotate the left end of the bezel away from the front panel. 4. Unhook the right end of the bezel and pull the bezel away from the expansion enclosure. Figure 6.
Figure 7. Hardware Alert Identifying the Expansion Enclosure with the Failed Power Supply 5. In the Hardware tab navigation pane, expand the expansion enclosure identified in the previous step. 6. Select Power Supplies. The status of each power supply is displayed in the Power Supplies tab. 7. Select the failed power supply. The location of the failed power supply is displayed in the Power Supply View tab. Figure 8.
Identifying the Failed Cooling Fan To determine which cooling fan 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 cooling fan. 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 cooling fan. Figure 9.
Figure 10. Rear View of the Expansion Enclosure Showing the Failed Cooling Fan Replacing a Power Supply/Cooling Fan Module Use this procedure to replace failed power supply/cooling fan modules. About this task You can replace power supply/cooling fan modules one at a time without shutting down the expansion enclosure. Steps 1. Use SupportAssist to send diagnostic data to Dell Technical Support. 2. Press the power switch on the power supply/cooling fan module to turn it off. 3.
Figure 11. Removing a Power Supply/Cooling Fan Module 1. Power supply/cooling fan module 2. Release tab 3. Power supply/cooling fan module handle 4. Power switch 5. Slide the replacement power supply/cooling fan module into the chassis until it is fully seated and the release tab clicks into place. 6. Connect the power cable to the power supply/cooling fan module and make sure the cable is plugged into a power outlet. 7. Secure the power cable using the hook-and-loop strap.
Figure 12. Securing the Power Cable 1. 8. Hook-and-loop strap Press the power switch on the power supply/cooling fan module to turn it on. NOTE: Allow several seconds for the expansion enclosure 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 power supply/cooling fan status indicator is off. 9.
• The SC120 holds up to 24 drives, which are numbered from left to right starting from 0. Figure 14. SC120 Expansion Enclosure 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.
