Removal and Replacement Procedures— Small Form Factor (SFF) Chassis
✎
If you are not replacing the old expansion card with a new card, install an expansion slot cover to
close the open slot. Insert the metal slot covering the open slot, then push the expansion slot latch
down to secure the slot cover in place
Ä
CAUTION: After removing an expansion card, you must replace it with a new card or cover the open
slot with a metal slot cover or a piece of tape for proper cooling of internal components. Failure to do so
may cause the system to overheat.
7.8 Drives
The computer supports up to three drives. This section describes the procedure for replacing or
upgrading the storage drives. You need a Torx T-15 screwdriver to remove and install the guide
screws on a drive.
Ä
CAUTION: Make sure personal files on the hard drive are backed up to an external storage device
before removing the hard drive. Failure to do so will result in data loss. After replacing the primary hard
drive, you need to run the Restore Plus! CD to load the factory-installed files.
7.8.1 Drive Positions
To verify the type and size of the storage device installed in the computer, run Computer Setup.
Drive Positions
Item Description Item Description
1 One standard 3.5-inch, one-third
height bay (1.44-MB diskette drive
shown)*
3 Internal 3.5-inch, one-third height bay
for hard drive
2 5.25-inch drive bay for optional
drives.
*If a 1.44-MB diskette drive is installed, it is configured with a diskette drive bezel as shown in
the illustration. If the computer contains an empty 3.5-inch drive bay, then a bezel blank is
installed instead. If you do not have a drive in this slot, you may later choose to install a 3.5-inch
device (such as a diskette drive, hard drive, or Zip drive). However, to install a 3.5-inch device
other than a diskette drive or hard drive, you must order the 3.5-inch device bezel to provide
proper air flow within the chassis.
