Statement 3
CAUTION:
When laser products (such as CD-ROMs, DVD-ROM drives, fiber optic devices, or
transmitters) are installed, note the following:
v
Do not remove the covers. Removing the covers of the laser product could result in
exposure to hazardous laser radiation. There are no serviceable parts inside the
device.
v Use of controls or adjustments or performance of procedures other than those
specified herein might result in hazardous radiation exposure.
DANGER
Some laser products contain an embedded Class 3A or Class 3B laser diode. Note
the following:
Laser radiation when open. Do not stare into the beam, do not view directly with
optical instruments, and avoid direct exposure to the beam.
8. Touch the static-protective package containing the drive to any unpainted metal
surface on the server; then, remove the drive from the package and place it on
a static-protective surface.
9. Set any jumpers or switches on the drive according to the documentation that
comes with the drive.
Note: You might find it easier to install the new drive into the appropriate
opening on the front, and then attach the cables.
10. If you are installing a 5.25-in. drive in bay 2, push the drive into the bay; then,
use the two screws to attach the drive to the drive cage. If you are installing a
3.5-in. drive in bay 2, you must attach the 5.25-in. conversion kit, supplied with
your option, to the 3.5-in. drive.
11. Determine whether the drive is an IDE or SCSI device; then, connect one end
of the appropriate signal cable into the back of the drive and the other end of
this cable into the appropriate IDE or SCSI connector on the system board.
v
If you are installing a SCSI removable-media drive, use the one-drop SCSI
cable that comes with the drive and connect it to SCSI channel B (SCSI2).
See “Power and signal cables for internal drives” on page 59 for additional
information about cabling drives and “System board internal cable
connectors” on page 34 for the location of IDE and SCSI connectors on the
system board.
v
If there are open connectors on the cables connecting existing IDE or SCSI
drives, this cable can be used to connect the new drive. The 4-connector
SCSI cable that comes with non-hot-swap model servers cannot be used to
connect a SCSI drive in bay 2.
12. Route the signal cable so that it does not block the airflow to the rear of the
drives or over the microprocessor and memory.
13. Connect the power cable to the back of the drive. The connectors are keyed
and can be inserted only one way.
