Module
The RG-N18000 switch adopts the module-based design. Compliant with industry standards, the design divides modules
and integrates module interfaces to ensure the switch system's functioning and independence of various function
modules.
The modules of the RG-N18000 switch provide 10/100/1000M auto-sensing Ethernet copper ports, 1000 Mbps/100 Mbps
SFP (single-mode/multi-mode) optical fiber interfaces and 10G/40G optical fiber interfaces.
M18014-CM
M18014-CM is the supervisor module of the RG-N18014 series switches and is designed with management and switching
functions.

External Port
The M18014-CM module provides five external ports:
 Universal Serial Bus (USB) port: By connecting to the USB port, the USB storage devices can store logs, host
version, alarms and other diagnosis information, facilitating online upgrade of switch software and storage of logs.
To secure data and prevent damage to the device, it is recommended to use high-quality flash disks
produced by reliable manufacturers. The USB port is compatible with most USB controllers but may be
unable to identify some USB disk models.
The USB flash disk must be installed to the USB port before you upgrade the software.
 Secure digital (SD) memory card slot: By connecting to the SD card slot, SD memory cards can store logs, host
version, alarms and other diagnosis information, facilitating online upgrade of switch software and storage of logs.
To secure data and prevent damage to the device, it is recommended to use high-quality SD memory cards
produced by reliable manufacturers. The SD card slot is compatible with most SD memory cards but may be
unable to identify some SD memory cards.
 Console port: As a serial communications port, it uses the RS-232 interface level and standard RJ-45 connector.
This port is used to connect the device to serial ports of background terminal computers to perform tasks including
system commissioning, configuration, maintenance, management, and host software loading.
 10/100/1000M MGMT port: As the 10/100/1000BASE-T Ethernet port, it uses the RJ-45 connector. This port can be
used to connect the device to the Ethernet port of the background computer to load programs. Use the standard
cable to connect the device to the Ethernet port of the background computer.

Data Center Manageability Interface (DCMI): DCMI implements the management for the data center devices. For
example, you can check the temperature, configure the serial port, reset the device, and power on/off device. These
operations cannot be achieved through the Console port or the MGMT port. Use the standard cable to connect the
device to the Ethernet port of the background computer.
Button
The M18014-CM module provides a Reset button, which is used to reset the system. If the button is held for less than five
seconds, it is a short press; if the button is held for five seconds or longer, it is a long press.
