How to Install Cisco Compatible UCS-MR-1X162RU-A

Installing this memory module is a straightforward, hot-pluggable process in compatible Cisco UCS servers. Follow these steps to ensure proper seating and operation:

1) Power down the server and unplug all power sources. Ground yourself to avoid static discharge. Open the cover or access panel to reach the memory slots.

2) Identify the correct memory slot. Refer to your UCS server hardware guide to locate the RDIMM slots that support 16GB dual‑rank modules. Remove any existing DIMMs if you are replacing them, and take care to note the seating order for optimal memory channel interleaving.

3) Align the module properly. The notch on the edge connector must align with the key in the slot. For RDIMMs, insert with even pressure along the edges to avoid bending pins. Do not force the module or bend it at an angle.

4) Seat the module firmly. Push straight down until the module is fully seated and the retention latches click into place, securing the DIMM. Confirm that both edges are locked and that the module sits evenly in the slot.

5) Reassemble any panels, reconnect power, and boot the server. Enter the system BIOS or POST screen to verify the memory is recognized and that ECC is active. Consider running a memory diagnostic or a quick UCS health check to confirm stability after installation.

6) If you are upgrading from a smaller capacity, observe the operating system and hypervisor memory metrics to ensure the new total memory capacity is being utilized effectively. In some configurations, you may need to adjust firmware or BIOS memory settings to maximize performance and stability.
