2 Module
The RG-CS88-08 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-CS88-08 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.

External Port
The CM88-CM module provides three 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.
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.
Button
The CM88-CM module provides a FUNC 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.
In case of a short press, the Status LED flashes in green, and the device resets within five seconds after the press.
In case of a long press, the Status LED flashes in green and then flashes in red; the device resets within five seconds
after the press.
Press the button, and the system starts to collect information, during which the device will not restart. After the
collection is complete, the device restarts automatically. Hold the button for a while and release it, the device restarts
automatically in five seconds.
