56 Installing System Components
Before You Begin
Hard drives are supplied in special hot-pluggable drive carriers that fit in the hard-drive bays. Depending
on your configuration, you received one of the following two drive carrier types:
• SATA drive carrier — Usable only with a SATA hard drive.
• SATAu drive carrier — Usable with either a SAS hard drive or a SATA hard drive with a universal
interposer card. The interposer card provides enhanced functionality that makes the SATA hard drive
usable in some storage systems.
NOTICE: Before attempting to remove or install a drive while the system is running, see the documentation for the
optional SAS RAID controller daughter card to ensure that the host adapter is configured correctly to support hot-
plug drive removal and insertion.
NOTE: It is recommended that you use only drives that have been tested and approved for use with the SAS
backplane board.
You may need to use different programs than those provided with the operating system to partition and
format SAS or SATA hard drives.
NOTICE: Do not turn off or reboot your system while the drive is being formatted. Doing so can cause a drive
failure.
When you format a high-capacity hard drive, allow enough time for the formatting to be completed.
Long format times for these drives are normal. A 9-GB hard drive, for example, can take up to 2.5 hours
to format.
Removing a Drive Blank
NOTICE: To maintain proper system cooling, all empty hard-drive bays must have drive blanks installed. If you
remove a hard-drive carrier from the system and do not reinstall it, you must replace the carrier with a drive blank.
The process for removing a drive blank depends on whether your system is configured with 3.5-inch or
2.5-inch hard drives.
For 3.5-inch hard drive configurations:
1
Remove the front bezel, if attached. See "Removing the Front Bezel" on page 53.
2
Insert your finger under the shrouded end of the blank and press in on the latch to eject the blank
outward from the bay.
3
Pry the ends of the blank outward until the blank is free.
For 2.5-inch hard drive configurations, remove the blank as you would the 2.5-inch hard drive carrier:
1 Remove the front bezel, if attached. See
"Removing the Front Bezel" on page 53
.
2 Open the drive blank release handle to release the blank. See
Figure 3-4
.
3
Slide the drive blank out until it is free of the drive bay.
