Parts Replacement Procedures
This section provides procedures for removing and replacing components and assemblies in your storage system:
Unless otherwise noted, each procedure assumes the following conditions:
You have read the safety instructions in your Product Information document. Always follow the instructions closely. While working on the system, do not attempt to service the
system except as explained in this guide and elsewhere in Dell documentation.
You can replace or reinstall a part by performing the removal procedure in reverse order, unless additional information is provided.
Recommended Tools
Most of the procedures in this section require the use of one or more of the following tools:
#2 Phillips-head screwdriver
Wrist grounding strap, as explained in the safety instructions found in your Product Information document
Standard flat-blade screwdriver
Removing and Installing Hard Drives
Your storage system features a SCSI backplane that simplifies cabling and configuring your storage system's SCSI hard drives. The SCSI backplane configures all SCSI IDs.
When used in combination with a host RAID controller that supports hot-pluggable drives, the SCSI backplane allows you to remove and insert hard drives without shutting down the
storage system. You can replace a failed drive without requiring network users to log off, thus avoiding potential loss of time and data. To verify that your RAID controller supports hot-
plugging, see your RAID controller documentation.
NOTICE:
If the storage system is connected to a supported RAID controller, you can remove and insert SCSI hard drives while the storage system is running. However, hot-
plugging hard drives without a supported card could result in data loss. See your RAID controller documentation to ensure that the host adapter is configured correctly to support
hot-plug hard drive removal and insertion. HBA cards do not support hot-plugging of drives while the system is running. For more information on supported cards, see your
system's readme file.
This section describes how to remove and install hard drives in your storage system.
CAUTION:
See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.
NOTICE:
Extra care must be taken when handling and storing the hard drives. The carriers provide some protection, but the hard drives can be damaged by rough handling.
When removing the hard drives from the storage system, place them on a padded surface. Never drop the hard drives.
