Make note of the location of SIMM modules for reference. 1. Remove memory modules by holding back the metal clips on the memory module connector, tilting the memory module and lifting it out of its connector. o Installing the New CPU Module 1. Remove the new CPU module Part No. 54-20674-01 from its packaging, and verify that it is at revision level E04. The revision level tag is typically located at the left of the bottom two EISA slots. Also verify that the system firmware is at level 2.0 or later. If the firmware is at a lower level, contact the Digital office for a copy of the latest revision. QUICK CHECK: Position the motherboard so that the EISA slots are at bottom left position, and memory slots are at top left. E163 is located below the second memory slot, and starting at the right end of the slot, it is the third component to the left. E125 is located below the sixth memory slot and starting from the right end of the slot, it is the third component to the left.

Install the SIMM memory modules which were removed from the original CPU module onto the revision E04 CPU module. To install, carefully insert the memory module at the proper angle (approximately 45 degrees) into the connector, and then rotate back so that it is latched-in by the metal clips. 3. Lower the CPU module into the case while slightly tilting the module to avoid interference with the enclosure. 4. Gently move the CPU module toward the rear of the enclosure until the serial and parallel port connectors insert into the openings in rear of the enclosure. 5. Make sure the screw holes are aligned with the stand-off's in the enclosure. 6. Install all of the screws (qty. 9) which fasten the CPU module to the enclosure. (DO NOT over tighten any of the screws.) 7. Re-connect power cables (PS1, PS2, and PS3) to the CPU module. 8. Re-connect the front panel signal cable to the CPU module. 9. Re-connect the battery cable to the CPU module. 10. Re-connect the fan power cable to the CPU module. 11. Install the Adaptec SCSI adapter card. Ensure the SCSI bus and floppy cables are re-connected properly. 12. Re-install all other ISA and/or EISA option cards, and associated internal cables. o Installing EISA or ISA option boards in the system unit. Use ALL ESD safety precautions to prevent DOA's on material in kit. ******************************************************************** * C A U T I O N * * * * The module, as with all modules, contain electrostatic discharge * * sensitive devices (ESDS).
