2: Installation of Customer Replaceable Components
Removing and Installing a 3.5-inch Drive in the Internal Drive Cage
The following instructions describe how to remove 3.5-inch drives from the internal
drive cage:
1. Remove the side panel as described in “Pre-installation Instructions” on page 16.
2. Disconnect all cables from the drive to be removed.
3. To remove the drive from a drive bay, press the drive rail plastic release tabs on both
sides of the drive and pull the drive out of the chassis. If the drive is hard to pull
out, you can facilitate the removal by gently pushing the drive from behind.
4. To remove a drive rail from the drive, pull the rail away from the drive by lifting one
end of the rail.
The following instructions describe how to install 3.5-inch drives in the internal drive
cage:
Note: Only low-profile (i.e., one-inch) drives can be mounted in the internal drive cage.
1. All drives are mounted on snap-on drive rails. The Silicon Graphics 230 Visual
Workstation comes with two sets of spare 3.5-inch drive rails. One set of spare
3.5-inch drive rails is located inside the chassis on the side of the 5.25-inch drive
bays. The other set is located inside a plastic bag attached to the side panel.
2. There are two different sets of drive rails for 3.5-inch drives. The difference between
the two sets is the distance between the wire clips. To choose which drive rail fits
your drive, place the drive rail wire clips next to the drive screw holes and verify
that the distance between the wire clips is the same as the distance between the two
screw holes. If the distance is the same, the drive rail is the correct one.
3. The drive rails for the 3.5-inch drives are not interchangeable. They have ‘R’ or ‘L’
markings that indicate which side they have to be mounted on. Before mounting the
rails to the drive, check to be sure the rail marked ‘L’ is on the left side of the drive
and the rail marked ‘R’ is on the right side of the drive, as shown in Figure 2-8.
4. To mount a drive rail to the drive, place one end of the drive rail wire clip into its
drive screw hole. Gently push on the middle of the drive rail until the other end of
the wire clip snaps into its screw hole. Make sure that the connectors face out.
Figure 2-8 illustrates the procedure.
