MPC-2121 provides two storage options—CFast card and SD card. The
storage slots are located on the left panel. You can install the OS in the
CFast card and save your data in the SD card. For a list of compatible
CFast models, check the MPC-2121 component compatibility report
available on Moxa’s website.
To install the storage devices, do the following:
1. Remove the two screws on the storage-socket cover.
The top slot is for the CFast card while the lower slot is for the SD card,
as indicated by the following illustration:
2. Insert a CFast or SD card into the respective slot using the push-push
mechanism.

Real-time Clock
The real-time clock (RTC) is powered by a lithium battery. We strongly
recommend that you do not replace the lithium battery without help from
a qualified Moxa support engineer. If you need to change the battery,
contact the Moxa RMA service team. The contact details are available at:
https://www.moxa.com/en/support/repair-and-warranty/product-repair
-service.
ATTENTION
There is a risk of explosion if the clock’s
lithium battery is
replaced with an incompatible battery.
Grounding the MPC-2121
Proper grounding and wire routing help to limit the effects of noise from
electromagnetic interference (EMI). Run the ground connection from the
ground screw to the grounding surface prior to connecting the power
source.

Powering On/Off the MPC-2121
Connect an M12 Connector to Power Jack Converter to the
MPC-2121’s M12 connector and connect a 40 W power adapter to the
converter. Supply power through the power adapter. After you have
connected a power source, the system power turns on automatically. It
takes about 10 to 30 seconds for the system to boot up. You can change
the power-on behavior of your computer by changing the BIOS settings.
To power off the MPC-2121, we recommend using the "shut down"
function provided by the OS installed on the MPC. If you use the Power
button, you may enter one of the following states depending on the power
management settings in the OS: standby, hibernation, or system
shutdown mode. If you encounter problems, you can press and hold the
Power button for 4 seconds to force a hard shutdown of the system.
