SECTION 5 - INSTALLATION
This section describes the procedures for installing the IRV-3702 All-In-One Single Board Computer
into your system. The following is a list of typical peripherals required to build a minimum system:
• Passive Backplane and Power Supply
• IBM PC/AT Type Keyboard
• Monitor
• Floppy or Hard Disk with MS-DOS, ROM-DOS, or PROMDISK Disk Emulator
INSTALLING THE DIMMS
When installing or removing the SDRAM DIMMs, be sure to first touch a grounded surface to
discharge any static electricity from your body. Use the following procedure to install the DIMMs:
1. Insert the first DIMM edge connector into the DIMM1 socket closest to the top of the board. Note
that the DIMMs are keyed and will only go in one way.
2. Push the DIMM into the connector carefully until it snaps into place.
3. Check to make sure the DIMM is inserted securely.
4. Insert the remaining DIMMs (if required).
To remove a DIMM, move the locking ejector tabs outward on each side of the DIMM and lift the
DIMM from the connector.
INSTALLING THE CPU
When installing or removing the CPU, be sure to first touch a grounded surface to discharge any static
electricity from your body. Use the following procedure to install the CPU:
1. Open the ZIF socket by lifting the release arm to its vertical position causing the sliding base plate
to move to the open position.
2. Align pin one (white dot or beveled edge) on the CPU chip with pin one of the ZIF (zero insertion
force) socket. Note pin 1 of the ZIF socket is located on the bottom right side of the socket. To
complete the installation gently press the CPU chip into place and return the release arm to its
locked position.
3. Double-check the insertion and orientation of the chip before applying power. Improper
installation will result in permanent damage to the chip. Refer to Appendix E for CPU speed and
configuration jumpers.
To remove the CPU chip, open the ZIF socket by lifting the release arm to its vertical position and
gently remove the chip.
INSTALLING THE PROMDISK-CHIP
When installing or removing the PROMDISK-Chip, be sure to first touch a grounded surface to
discharge any static electricity from your body. Use the following procedure to install the PROMDISK-
Chip:
1. Align pin one (square pad) on the PROMDISK-Chip with pin one of socket U31 on the CPU board.
