Installing Heatsinks On High-Power Drives - Intergraph InterServe 9000 System Reference Manual

Installing Heatsinks on High-Power Drives

If you plan to use SCSI drives whose power exceeds 15 watts, you must install heatsinks on those
drives.
CAUTION
If you install high-power drives, you must also install additional system fans.
This requires that you work inside the chassis and that you are a technically
qualified service technician. See "Installing Fans for High-Power Drives"
(page 100) in part two of this document, "Service Technician's Guide."
1. Position each heatsink (B in Figure 21) so that the three screw holes in the heatsink align with
their corresponding holes in the hard drive. The holes are spaced apart so that you can position
the heatsink in only one way: with the fins extending along the side and the top of the hard
drive. The "top" of the drive has the label (C in Figure 21); the "bottom" has the exposed
circuit board (A).
2. Use three screws (D) to attach each heatsink to the drive.
3. To insert the drive into the hot-docking bay, you must attach a carrier to the drive. See
"Mounting a SCSI Hard Disk Drive in a Plastic Carrier" on page 73.
