79 Installation and Service Guide: Color Controller E-45
Replacing parts
4
Install the four screws that secure the power supply to the connector panel of the chassis.
5
Replace the motherboard (see page 64 ).
6
Connect one of the SATA power cables to the power connector on the dual data/power cable that connects to the DVD
drive.
7
Connect three of the other SATA power cables to the SATA power connectors on the hard disk drive.
8
Connect the power cables to the motherboard (see Figure 22 on page 49 and Figure 28 on page 61):
• 8-pin power cable to connector PWRCONN1
• 24-pin power cable to connector J18
9
Replace the tie-wraps that you removed earlier.
10
Reassemble the E-45 and verify its functionality (see page 84 ).
Hard disk drive
The factory-installed hard disk drive is formatted and loaded with system software, network drivers, and printer fonts. The
hard disk drive is also used to store spooled print jobs. Available space on the hard disk drive is displayed in
Command WorkStation.
If you replace the hard disk drive with a new one, you must restore the backup (see page 86 ) or install system software as
described on page 97 . (Spare hard disk drives are not shipped with preinstalled system software.)
It is unlikely that both the hard disk drive and the motherboard are defective. Avoid replacing both to solve one problem. If
troubleshooting strategies (such as checking cables and connections; see
page 104 ) do not solve the problem, and you
suspect either the hard disk drive or the motherboard is at fault, use the following order to troubleshoot: replace the hard
disk drive, install system software, and then check to see if the problem persists. If it does, perform other procedures, such
as replacing the motherboard (see
page 63 ).
Proper handling
• Use proper ESD practices when grounding yourself and the E-45.
•
Keep magnets and magnetic-sensitive objects away from the hard disk drive.
• Do not remove the screws on top of the hard disk drive. Loosening these screws voids the warranty.
•
Never drop, jar, bump, or put excessive pressure on the hard disk drive.
• Handle the hard disk drive by its sides and avoid touching the printed circuit board.
•
Allow the hard disk drive to reach room temperature before installation.
Important:
Do not replace the hard disk drive and the motherboard at the same time. Doing so in the wrong order,
without updating the system (see page 63 ), will cause the system to malfunction.
Important:
Improper handling can damage a hard disk drive. Handle the hard disk drive with extreme care.
