CRU Replacement and Server Upgrades 4-45
Replacing the Device Module
Your system contains two standard PC AT compatible peripheral devices that
are housed in the device module. The standard peripheral devices are as follows:
!
Super floppy disk drive
!
24X CD-ROM drive (supports 650 MB CD media).
The device module is a single CRU and is not hot-pluggable.
You must open the front door of the tower cabinet or the front cover of the rack-
mount system to turn the server power off before removing or installing the
device module.
!
CAUTION
CD-ROM devices contain a laser system and are classified
as CLASS 1 LASER PRODUCTS. In case of any trouble
with a CD-ROM, please contact your nearest service
representative. To prevent direct exposure to the laser
beam, do not try to open the enclosure.
Use of controls or adjustments or performance of
procedures other than those recommended by the
manufacturer may result in hazardous radiation exposure.
To replace the device module perform the following procedures (see Figure
4-56).
1. Observe the safety and ESD precautions listed at the beginning of this
chapter.
2. Unlock and open the front door on the tower cabinet or front covers on the
rack-mount system. See

3. Power off the system. Ensure the power cords are unplugged from the AC
wall outlet.
4.
Remove the two screws securing the device module to the front panel of the
cabinet.
5. While holding the upper and lower tabs protruding from the device module
