80Installation and Service Guide Color Controller E-46A
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 27 on page 50 and Figure 33 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-46A and verify its functionality (see page 86).
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 88) or install system software
as described on page 101. (Spare hard disk drive is 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 111) 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-46A.
• 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, shake, 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.
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.
Improper handling can damage a hard disk drive. Handle the hard disk drive with extreme care.
