1 About the SC400 Series Expansion Enclosure An SC400 series expansion enclosure provides expansion storage for a Dell Storage Center. The SC400 series expansion enclosure connects directly to the SAS ports on the back of the storage system. SC400 Series Expansion Enclosure Overview The SC400 is a 2U expansion enclosure that supports up to 12 3.5‐inch hard drives installed in a four‐column, three-row configuration. The SC420 is a 2U expansion enclosure that supports up to 24 2.
Item Name Icon Description 1 System identification button The system identification button on the front control panel can be used to locate a particular expansion enclosure within a rack. When the button is pressed, the system status indicators on the control panel and the Enclosure Management Module (EMM) blink blue until the button is pressed again. 2 Power LED The power LED lights when at least one power supply unit is supplying power to the expansion enclosure.
Item Name Description 5 Power switches (2) Controls power for the expansion enclosure. There is one switch for each power supply. 6 Power supply unit and cooling fan module (PS2) 600 W power supply SC400 Series Expansion Enclosure EMM Features and Indicators The SC400 Series includes two enclosure management modules (EMMs) in two interface slots. Figure 4.
SC400 Series Expansion Enclosure Drives Dell Enterprise Plus hard disk drives (HDDs) and Dell Enterprise Plus solid-state drives (SSDs) are the only drives that can be installed in SC400 series expansion enclosures. If a non-Dell Enterprise Plus drive is installed, the Storage Center prevents the drive from being managed. The drives in an SC400 expansion enclosure are installed horizontally. The drives in an SC420 and SC420F expansion enclosure are installed vertically.
2 Replacing SC400 Series Expansion Enclosure Components This chapter describes how to remove and install components of the SC400 series 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.
• Unplug the expansion enclosure chassis before you move it or if you think it has become damaged in any way. When powered by multiple AC sources, disconnect all power sources for complete isolation. 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.
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. Replacing the Front Bezel 5. Hook the right end of the replacement bezel onto the front panel of the expansion enclosure. 6.
Identify the Failed Hard Drive To determine which hard drive failed, use the Storage Manager. 1. Use the Storage Manager to connect to the Storage Center. 2. Click the Hardware tab. 3. In the Hardware tab navigation pane, select the Storage Center. 4. In the Hardware Alerts area, find the hardware alert that identifies the expansion enclosure with the failed hard drive. Figure 9. Hardware Alert Identifying the Expansion Enclosure with the Failed Hard Drive 5.
Figure 10. Front View of the Expansion Enclosure Showing the Failed Hard Drive Replace a Hard Drive Use this procedure to replace a failed hard drive. Prerequisite Use SupportAssist to send diagnostic data to Dell Technical Support Services. About this task Hard drives can be replaced without shutting down the expansion enclosure. CAUTION: To prevent a storage system reset, at least one powered drive must remain installed in the primary chassis when multiple drives are replaced. Steps 1.
3. 4. Hard drive carrier 4. Hard drive slot Press the release button on the replacement hard drive to open the hard drive carrier release handle. NOTE: Hold the hard drive by the plastic part of the hard drive carrier or the handle. 5. Insert the hard drive carrier into the hard drive slot until the carrier make contact with the backplane. CAUTION: Do not remove the hard drive blanks that are installed in hard drive slots that are not occupied.
Figure 13. Installing Dell Enterprise Hard Drives in an SC420 or SC420F 3. Close the hard drive carrier handle to lock the hard drive in place. 4. Continue to push firmly until you hear a click and the hard drive carrier handle fully engages. 5. Insert drive blanks into any open slots in the expansion enclosure. All the drive slots in the expansion enclosure must be filled with a drive or drive blank. Replacing Rack Rails Rack rails are used to install SC400 series expansion enclosures into a rack.
Post-Replacement Procedures Perform the procedures described in this section after replacing a component of an SC400 series expansion enclosure. Send Diagnostic Data Using Dell SupportAssist After replacing components, use Dell SupportAssist to send diagnostic data to Dell Technical Support Services. 1. Use Dell Storage Client to connect to the Storage Center. 2. In the Summary tab, click Send SupportAssist Information Now, which is located under SupportAssist Actions in the Status pane.
3 Troubleshooting SC400 Series Components This section contains basic troubleshooting steps for components inside the SC400 series expansion enclosures. Troubleshooting Power Supply/Cooling Fan Modules Use these steps to troubleshoot power supply/cooling fan modules. 1. Check the status of the power supply/cooling fan module using the Dell Storage Client. 2. Determine the status of the power supply/cooling fan module LEDs.
Troubleshooting the Control Panel Use these steps to troubleshoot the control panel. 1. Determine the status of the control panel LEDs. If the LEDs are not lit, and the enclosure is powered on, the control panel has failed. 2. Reseat the control panel by removing and reinstalling it. CAUTION: The storage system and expansion enclosures must be shut down before reseating the control panel.
