“Motherboard parts and connectors” on page 26 . The printer interface board is keyed to fit only one way.
2. Replace the mounting screw that secures the printer interface board to the chassis.
Insert the mounting screw through the chassis and into the hole on the board mounting bracket (see “Remove the printer
interface board” on page 21 ). Tighten the screw completely.
3. Connect one end of the 10-pin power button cable to J351 connector on the printer interface board. Connect the
other end to the J29 connector on the motherboard.
The cable connector is keyed to fit only one way.

after service” on page 43 ).
■ DIMM
DIMM (dual in-line memory module) is held in place by a lever at the end of DIMM slot. The motherboard contains two DIMM
slots (See
“Motherboard parts and connectors” on page 26 ).
NOTE:
• DIMMs must be correctly installed in order for the imagePRESS Server to function properly. To ensure proper operation,
replace DIMMs only with approved replacement DIMMs.
• Approved DIMMs are available from your authorized service/support center.
● Replace a DIMM

imagePRESS Server” on page 18 ).
To access the DIMMs, you must remove the chassis cover.
