Removing the motherboard
Before you remove the motherboard, you must remove:
• All boards installed on the motherboard
• All cables connecting the motherboard to other components (including the three motherboard power cables, back fan
cables, DVD/HDD data/power cables, Fiery QuickTouch USB cable, and SW/LED cable)
To remove motherboard components from the motherboard
1 Shut down the E-85, remove all cables from the back, and then open the system (see page 48).
To access the motherboard, you must remove the left panel.
2 Remove the printer interface board assembly from the motherboard (see page 55).
To access the mounting screws for the board brackets, you must first remove the bracket cover plate from the connector
panel.
3 Remove the following cables attached to the motherboard (for the location of each connector on the motherboard, see
Figure 24 on page 46 and Figure 25 on page 47):
• Back fan cable
• Mini SAS HDD/DVD data cable
• Fiery QuickTouch USB cable
• 8-pin motherboard power cable (PW2)
• 8-pin motherboard power cable (PW3)
• 24-pin motherboard power cable (PW1)
• Power/LED cable (FPIO_1)
Important: Do not move or change any of the default jumper configurations.
Caution:Follow standard ESD precautions (see page 11) when handling components. During service to the
motherboard, avoid using excessive force and always place the motherboard on a grounded, non-metallic, static-free
surface. Never allow any metal to touch the solder contacts on the underside of the motherboard, especially beneath
the battery socket. Improper handling can short-circuit and permanently damage the motherboard.
