Configuring the storage devices
The system supports up to four 3.5-inch hot-plug SATA/SAS hard disk
drives. An optional optical drive can also be added to the server.
Accessing the drive bays
Since SAS/SATA drives have hot-plug capability, you do not need to
access the inside of the chassis or power down the system to install or
replace SAS/SATA drives. Proceed to the next step for instructions.
Note: The operating system you use must have RAID support to
enable the hot-plug capability of the SATA drives.
Caution! When working around the SATA backplane, do not
touch the backplane with any metal objects and make sure no
cables touch the backplane. Also, regardless of how many SATA
drives are installed, all four drive carriers must remain in the
chassis to maintain proper airflow.
Guidelines for configuring hard disk drives
Observe these guidelines when replacing or installing a hard disk drive.
• Use only qualified SAS or SATA HDDs. To purchase a SAS or SATA
HDD, contact your local representative.
• Install hard disk drives in the special drive carriers that fit in the
hard drive bays.
• Before removing a hard disk drive, make sure to back up all
important system files.
• Check hard disk drive status by checking the status LED indicators
on the HDD carrier.
• The recommended HDD installation order is from left to right.
