• Remove any jewelry or metal objects from your body because they are excellent metal conductors
that can create short circuits and harm you if they come into contact with printed circuit boards or
areas where power is present.
• Do not lift a expansion enclosure chassis by the handles of the power supply units (PSUs). They are
not designed to hold the weight of the entire chassis, and the chassis cover may become bent.
• Before moving a expansion enclosure chassis, remove the PSUs to minimize weight.
• Do not remove drives until you are ready to replace them.
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 an SC180 expansion
enclosure.

Sending Diagnostic Data Using Dell SupportAssist

Use Dell SupportAssist to send diagnostic data to Dell Technical Support Services.
1. Click Send SupportAssist Data Now. The Send Support Assist Data Now dialog box appears.
2. Select Storage Center Configuration and Detailed Logs.
3. Click OK.

Contacting Dell Technical Support Services

Contact Dell Technical Support Services to let them know that you are performing a repair.
Request that Dell Technical Support Services suspend alerts for the expansion enclosure and ask for a
pre‐installation system check.

Shutting Down the Storage System and Expansion Enclosures

If the replacement component is not hot-swappable, use the Dell Storage Client to shut down the
storage system and expansion enclosures. Shutting down the storage system and expansion enclosures
results in a system outage, so plan to perform these procedures during a maintenance window.
1. Before shutting down the storage system and expansion enclosures, make sure you identify the
failed part.
2. From the Actions menu, select System→ Shutdown/Restart. The Shutdown/Restart dialog box
appears.
3. Select Shutdown and click OK.
4. When the storage system and expansion enclosures are shut down, switch off both power switches
and unplug the power cables from the expansion enclosure.
