CAUTION:
When laser products (such as CD-ROMs, DVD drives, fiber optic devices, or
transmitters) are installed, note the following:
•
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.
•
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
Complete the following actions to install a CD-ROM drive.
1.
Remove the new drive from its protective wrapper, and place it component-side
down on an antistatic surface.
2.
Install the drive cable adapter PCB to the CD-ROM drive by connecting it into the
back of the CD-ROM drive and securing the two small screws at the ends of the
PCB.
3.
Install the drive carrier assembly over the drive such that the following conditions
are met:
•
The end with the thumbscrew is oriented toward the rear of the drive.
•
The two ends of the drive cable adapter PCB are inserted into the slots in the
carrier.
•
The four metal tabs (two on each half of the drive carrier) are aligned with the
holes in the drive.
•
Ensure that the tab is locked.
4.
Pick up the drive carrier assembly and place it face up (carrier side down) on the
chassis such that the front of the drive is aligned with the opening in the front of
the chassis.
5.
Grasp the sides of the assembly and slide it forward such that the front part of the
drive comes through the opening in the chassis. Make sure that the thumbscrew
at the rear of the drive carrier assembly aligns with the hole in the surface of the
chassis.
6.
Tighten the thumbscrew at the rear of the drive carrier assembly.
7.
Install the top cover (see "Top cover installation" on page 170 ).
The Processor/Memory complex mounts memory boards to the processor board and
forms a module that you can remove from the main system chassis. To access this
module, you need to remove the access door on the right side of the chassis as you
face its front, remove four securing screws on the left side of the chassis, and slide the
Processor/Memory complex out of the system.
