GA-1121 assembly
GA-1121 assembly
The GA-1121 board has a 850MHz CPU that controls the video image data transferred
to and from the copier. The GA-1121 board provides the Ethernet networking interface,
controls hard disk drive functions, and handles the communication between the
GA-1121 and external devices.
The GA-1121 board has two DIMM sockets (see Figure 3-4 on page 3-8 and also
“DIMMs” on page 3-13). The GA-1121 board is configured with 256MB of memory at
the factory.
The GA-1121 connects to the copier via the copier interface connector at the back of the
GA-1121 assembly. When the entire GA-1121 assembly is installed inside the copier, the
following connectors are accessible from the faceplate:
• 25-pin parallel port for dongle
• 10/100BaseT network port
• 36-pin parallel port for system software installation
Following are instructions for accessing, removing, and replacing the GA-1121 board, as
well as components such as the CPU fan, DIMMs, battery, intake fans, and HDD.
Make sure you attach an ESD grounding wrist strap and follow standard ESD
(electrostatic discharge) precautions before following this procedure.
