2: Installation of Customer Replaceable Components
The following instructions describe how to install 3.5-inch drives in the front-access drive
cage:
Note: Use of 10,000 RPM drives in the front-access drive cage is not recommended.
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 on
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. Figure 2-8 illustrates the procedure.
