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.
