Outlines how to install a DIMM module in QC Series 1U or 4U platforms
REQUIREMENTS
- QC 1U or 4U hardware
- DIMM module on-site
- Phillips head screwdriver (QC 1U Gen 1 only)
PROCESS
Prior to starting, power down the node and disconnect cabling. Loosen the two black thumbscrews on the front of the node and remove the node from the rack.
QC 1U Hardware (Gen 2)
- Loosen the thumbscrew on the back of the node
- Slide the top panel towards the back of the node to remove and expose the black baffle covering the DIMMs
- Lift the black baffle to access the DIMM slots
- Identify the location of the defective DIMM using the following image
- Press down on the two retaining clips to release and remove the DIMM
- Insert the new DIMM into the slot verifying that the retaining clips lock into position
- Reposition the black baffle cover over the DIMM slots
- Replace the top panel and tighten the rear thumbscrew to lock it in place
Once the DIMM replacement is complete, install the node back into the rack, tighten the two black thumbscrews, reconnect all cabling and power on the node.
QC 1U Hardware (Gen 1)
- Use the Phillips head screwdriver to remove the five screws securing the top panel
- Slide the panel towards the back of the node to remove and expose the black baffle covering the DIMMs
- Lift the black baffle to access the DIMM slots
- Identify the location of the defective DIMM using the following image
- Press down on the two retaining clips to release and remove the DIMM
- Insert the new DIMM into the slot verifying that the retaining clips lock into position
- Reposition the black baffle cover over the DIMM slots
- Replace the top panel and the install the five anchor screws to secure
Once the DIMM replacement is complete, install the node back into the rack, tighten the two black thumbscrews, reconnect all cabling and power on the node.
QC 4U Hardware
The QC Series 4U has 16 DIMMs total. Once the top panel is removed, 12 are accessible. To access the remaining four slots, remove the hard drive bay by following the steps in the Remove the Hard Drive Bay section below.
- L oosen the thumbscrew on the back of the node securing the top panel
- Slide the panel towards the back of the node to remove
Note: The hard drive drive bay indicated in the image above must be moved in order to access the final four DIMM slots. - Identify the location of the defective DIMM using the following image
Note: Only 12 of the 16 DIMM slots are accessible at this point. If your defective DIMM is in one of the slots covered by the hard drive bay (G1-H2), refer to the steps for moving it later in this document. - Press down on the two retaining clips on either side of the DIMM to release and remove
- Insert the new DIMM into the slot verifying that the retaining clips lock into position
- Replace the top panel and tighten the rear thumbscrew to lock it in place
Remove the Hard Drive Bay
- Loosen the single thumbscrew anchoring the hard drive bay inside the chassis
- Loosen the four thumbscrews on the back of the chassis anchoring the drive enclosure
- Lift the hard drive enclosure out of position to expose the 4 DIMMs making sure not to disconnect any cables
- Proceed with installing the DIMM module as outlined above
- Replace the drive enclosure (if removed) and re-tighten the five anchoring thumbscrews
- Replace the top panel and tighten the rear thumbscrew to lock it in place
Once the DIMM replacement is complete, install the node back into the rack, tighten the two black thumbscrews, reconnect all cabling and power on the node.
RESOLUTION
You should now be able to successfully install a DIMM module in QC series hardware
