REPLACE
THE
FANS
1.
Replace the two screws that secure the fan to the GA-1121 tray; be sure to hold the nuts
on the inside of the corner mounting.
Be sure to position the fan so that the fan blades are closest to the GA-1121 tray.
2.
If you removed intake fan 1, replace the fan cable to board connector J353.
3.
If you removed intake fan 2, replace the fan cable to board connector J352.
4.
Reassemble the GA-1121 and verify functionality (see page 3-22).
Hard disk drive
The factory-installed hard disk drive (HDD) is formatted and loaded with all GA-1121
software, including operating software, system software, network drivers, and printer
fonts.
Instructions for installing system software are provided to service technicians in a separate
kit and also are included in this guide.
If you are replacing the HDD, you need:
• The appropriate System Software CD
• The latest version of user software (for networked computers that will be printing to
the GA-1121)
Proper handling
Handle the hard disk drive with care:
• Use proper ESD practices when grounding yourself and the GA-1121.
• Keep magnets and magnetic-sensitive objects away from the HDD.
• Do not remove the screws on top of the HDD. Loosening these screws voids the
warranty.
• Never drop, jar, or bump the HDD.
• Handle the HDD by its sides and avoid touching the printed circuit board assembly.
• Allow the HDD to reach room temperature before installation.
Hard disk drive problems may be a result of the following:
• Loose or faulty connection
• Faulty hard disk drive
