Memory Configuration Rules

rp54xx Servers have 16 slots (8 DIMM pairs) for memory DIMMs. These slots are numbered 0a/b, 1a/b,... 7a/b. 8 of these slots (4a/b - 7a/b) are disabled on rp5400 Servers. rp5450 Servers can access all slots. rp5400 and rp5450 Servers have DIMM slots located on the System Board.

rp5470 Servers install DIMMs using memory carriers. The memory carriers fit into slots on the system Board.

The following rules govern the installation of memory DIMMs for rp5400, rp5450, and rp5470 Servers:

  • Memory must be installed in DIMM pairs.

  • The capacity of DIMMs within a pair must be the same.

  • Install DIMMs with the greatest capacity in the lowest slot numbers.

  • Install DIMMs the following slot order: 0a/b, 1a/b, 2a/b, 3a/b, and so on.

Installing rp5400 and/or rp5450 DIMMs

  1. Power down and unplug the rp54xx Server.

    NOTE: DC voltages are present when the server is connected to AC power. Do not attempt to install or service: CPUs, memory, PSMs, the platform monitor or PCI I/O cards installed in non-turbo slots (1-6) while DC voltage is present. Failure to observe this warning may result in damage to the server.

  2. Make the top of the server accessible for service.

  3. Loosen the captive T-15 screws that hold the top cover in place, then grasp the strap handle, raise the cover slightly, and pull the cover toward the front of the server to free the cover tabs from the slots in the chassis. The air baffle will be exposed.

  4. Loosen the four (4) captive T-15 screws on the air baffle. Grasp the two handles on the baffle, and lift and remove the baffle.

  5. Observe electrostatic discharge (ESD) precautions.

  6. Refer to the following graphic for memory slot locations.

    Locate the correct DIMM pair slots. Insert the DIMM connectors into the guides until the card snaps firmly in place. It may be necessary to apply downward force using the palm of your hand on the DIMM. Observe the top of the DIMM to make sure one side is not higher than the other.

    NOTE: It may be necessary to remove PSM 1 when installing a DIMM in slot 0a and PSM 0 when installing a DIMM in slot 1b. If either PSM is removed to install memory, ensure it is re-installed.

  7. Replace the air baffle. Tighten the four captive screws to secure the air baffle in place.

  8. Replace the top cover. Slide the cover tabs into the slots in the chassis and close the cover. Tighten the two captive screws to secure the top cover in place.

  9. For rack configurations, insert the rp54xx Server back into the rack.

  10. For deskside enclosure configurations, replace the deskside enclosure cover.

  11. Power the rp54xx Server on.

  12. Use the BCH command in me to verify the system recognizes the memory that you have just added.

Installing rp5470 DIMMs

  1. Power down and unplug the rp54xx Server.

    NOTE: DC voltages are present when the server is connected to AC power. Do not attempt to install or service: CPUs, memory, PSMs, the platform monitor or PCI I/O cards installed in non-turbo slots (1-6) while DC voltage is present. Failure to observe this warning may result in damage to the server.

  2. Make the top of the server accessible for service.

  3. Loosen the captive T-15 screws that hold the top cover in place, then grasp the strap handle, raise the cover slightly, and pull the cover toward the front of the server to free the cover tabs from the slots in the chassis. The air baffle will be exposed.

  4. Loosen the four (4) captive T-15 screws on the air baffle. Grasp the two handles on the baffle, and lift and remove the baffle.

  5. Observe electrostatic discharge (ESD) precautions.

  6. Refer to the following graphic for memory carrier locations.

    1. Locate the memory carrier and pull up on the extractor levers on each end of the memory carrier to unseat the memory carrier from its socket.

    2. When the memory carrier unseats from the socket, pull it away from the System Board.

    3. Loosen the captive screws that secure the DIMM Clip and remove the DIMM Clip from the memory carrier.

    4. Seat the memory DIMM into its socket on the memory carrier.

    5. Press the extractor levers on each end of the memory DIMM slot inward until the levers snap into place.

    6. Attach the memory clip to the memory carrier with the DIMM slot markings on the top of the memory clip aligned with the DIMM slot markings on the memory carrier.

    7. Secure the memory clip using the captive screws.

    8. Seat the memory carrier into the appropriate slot on the System Board.

    9. Push down on the extractor levers and snap them into place.

  7. Replace the air baffle. Tighten the four captive screws to secure the air baffle in place.

  8. Replace the top cover. Slide the cover tabs into the slots in the chassis and close the cover. Tighten the two captive screws to secure the top cover in place.

  9. For rack configurations, insert the rp54xx Server back into the rack.

  10. For deskside enclosure configurations, replace the deskside enclosure cover.

  11. Power the rp54xx Server on.

  12. Use the BCH command in me to verify the system recognizes the memory that you have just added.
