Adding an 8, 16, or 32 Gigabyte DIMM to a Cisco Nexus 9300 Series Switch
Cisco provides two modes of operation for Cisco Nexus 9300 series switches: Cisco NX-OS Software and Cisco Application Centric Infrastructure (Cisco ACI™). You can use Cisco NX-OS software to deploy the switches in standard Cisco Nexus switch environments (NX-OS mode). Cisco ACI™ platform takes full advantage of an automated, policy-based, systems-management approach (ACI mode).
Cisco Nexus switches may require an upgrade in system memory if you ordered a switch with base memory. The following are two use cases for additional memory upgrade:
1. To support the maximum route scale in Cisco NX-OS (check NX-OS Scalability Guide for details).
2. To support Cisco ACI software where system memory is less than 32 GB.

To check how much system memory is available, use the show system commands. Examples for Cisco NX-OS and Cisco ACI are below:
· Get the 8G DIMM as a spare, PID: NXK-MEM-8GB
· Get the 16G DIMM as a spare, PID: NXK-MEM-16GB
· Get the 32G DIMM as a spare, PID: NXK-MEM-32GB
1. Turn the power off before removing the access panel of the switch.
2. Wear an ESD wrist strap and place antistatic foam or antistatic padding under the DIMM.
3. Remove the DIMM installed in slot 3 and add the new DIMM, in addition to the standard memory DIMM already installed, in slot 1.
Remove the screws and the DIMM access panel (see figure 1).
Remove the old DIMM from slot 3.
Align the 8G, 16G or 32G DIMM card to DIMM slot 3 inside the chassis. Push the DIMM card into the slot until it is fully inserted (see figure 1).
