QNAP TS-h987XU-RP - Replacing Memory Modules

7. Power on the NAS.
Replacing Memory Modules
The NAS has four memory slots. You can increase the memory capacity of the NAS by upgrading the
memory module.
Use only QNAP memory modules to maintain system performance and stability. For NAS devices with more
than one memory slot, use QNAP modules with identical specications.
Important
Ensure the following when replacing memory modules:
• When installing only one module, use slot 4.
• When installing two modules, use slots 2 and 4. Ensure that the modules are identical.
• When installing four modules, use slots 2 and 4 for the rst pair, and slots 1 and 3 for
the second pair. Ensure that each pair uses identical modules.
For details on slot numbering, see System Board.
Warning
• Only qualied personnel should perform the following steps. Failure to follow
instructions can result in serious injury or death.
• Observe electrostatic discharge (ESD) procedures to avoid damage to components.
