SC180 Expansion Enclosure Drive Numbering In the SC180 expansion enclosure, the drive slots are numbered 1–42 in the top drawer and 43–84 in the bottom drawer. Dell Storage Client identifies drives as XX-YY, where XX is the number of the unit ID of the expansion enclosure, and YY is the drive position inside the expansion enclosure.

Always follow these safety precautions to avoid injury and damage to Storage Center equipment. If equipment described in this section is used in a manner not specified by Dell, the protection provided by the equipment could be impaired. For your safety and protection, observe the rules described in the following sections.
The resulting electrical discharge can damage electronic components and printed circuit boards. Follow these guidelines to protect your equipment from ESD: • Dell recommends that you always use a static mat and static strap while working on components in the interior of the expansion enclosure chassis. •...
Shut Down the Storage System If the field replaceable unit (FRU) is not hot-swappable, use the Dell Storage Client to shut down the storage system. Shutting down the storage system results in a system outage, so plan to perform these procedures during a maintenance window.
When the storage system is shut down, unplug the power cables from the storage system and expansion enclosures. Replacing PSUs The SC180 expansion enclosure supports two hot-swappable power supply units (PSUs). If one unit fails, the second unit continues to provide power to the expansion enclosure. Identifying the Failed PSU To determine which power supply unit (PSU) failed, use the Dell Storage Client.
Use this procedure to replace a failed power supply unit (PSU). Prerequisites Use SupportAssist to send diagnostic data to Dell Technical Support Services. About this task You can replace PSUs one at a time without shutting down the expansion enclosure.

Connect the power cable to the PSU and make sure that the cable is plugged into a power outlet. Secure the power cable using the clip. Figure 11. Securing the power cable Press the power switch on the PSU to turn it on. Replacing SC180 Expansion Enclosure Components...
When the PSU is functioning properly, the Power OK indicator turns green and the PSU fault and AC fault indicators are off. In the Dell Storage Client, make sure that the replacement PSU is recognized and shown as up and running.
Use this procedure to replace a failed cooling fan module. Prerequisites Use SupportAssist to send diagnostic data to Dell Technical Support Services. About this task You can replace cooling fan modules one at a time without shutting down the expansion enclosure.
Page 23
Battery and Fan fault LEDs are off. In addition, the cooling fan status indicator turns green in the Dell Storage Client. In the Dell Storage Client, make sure that the replacement cooling fan module is recognized and shown as up and running.
Replacing Hard Drives The SC180 expansion enclosure supports up to 84 3.5‐inch hot‐swappable hard drives installed in a two‐ drawer, three‐row, 14‐column configuration. Hard drives are connected to a backplane using Disk Drive in Carrier (DDIC) hard drive carriers. Identifying the Failed Hard Drive To determine which hard drive failed, use the Dell Storage Client.
Hard drives can be replaced one at a time without shutting down the expansion enclosure. Steps Find the SC180 and drawer that contains the failed drive. To identify the drawer with the failed driver, look for a drawer fault LED.

WARNING: Keep fingers clear of the chassis as the drawer is closed. In the Dell Storage Client, make sure that the replacement hard drive is recognized and shown as up and running. If the Dell Storage Client informs you that there are unassigned hard drives, see the Dell Storage Manager Client Administrator’s Guide for instructions on managing unassigned hard drives.
Identifying the Failed Enclosure Management Module To determine which enclosure management module (EMM) failed, use the Dell Storage Client. Start the Dell Storage Client and connect to the Storage Center that has an expansion enclosure with a failed EMM. Click the Hardware tab.
NOTE: Make sure the cables are labeled before disconnecting them from the EMM. Steps Use SupportAssist to send diagnostic data to Dell Technical Support Services. Disconnect the SAS cables connected to the EMM. Push the release tab to the right and pull the release lever away from the chassis.
Push the release lever toward the chassis until it clicks into place. Reconnect the SAS cables to the EMM. Replacing Rack Rails Rack rails are used to install the SC180 expansion enclosure into a rack. Prerequisites Use SupportAssist to send diagnostic data to Dell Technical Support Services.
NOTE: Always turn on the expansion enclosure before turning on the storage system. Turn on the storage system by pressing the power switches on the PSUs. Use the Dell Storage Client to make sure the replacement part is recognized and shown as up and running.
Troubleshooting SC180 Components This section contains basic troubleshooting steps for components inside the SC180 expansion enclosures. Troubleshooting Cooling Fan Modules To troubleshoot cooling fan modules: Check the status of the cooling fan module using the Dell Storage Client. Determine the status of the cooling fan module LEDs.
Remove the EMM. b. Verify that the pins on the backplane and the EMM are not bent. If any pins are bent, do not attempt to correct them, instead, contact Dell Technical Support Services for further instruction. c. Reinstall the EMM.
