Replacing Memory Modules - QNAP ES2486dc User Manual

Replacing Memory Modules

Each storage controller has eight memory slots. You can increase the memory capacity of the NAS by
upgrading the memory module.
Use only QNAP modules of the same type and capacity to maintain system performance and stability. You
can purchase QNAP memory modules from authorized resellers.
