1 Product Introduction
The RG-SF2920 series switches are simplistic optical switches released by Ruijie Networks for all-optical network
scenarios.
The switches adopt a new hardware architecture design to reduce noise, save energy, and implement flexible installation.
They are equipped with built-in power supplies, metal housings, and network ports, ensuring reliability and stability. They
are suitable for indoor scenarios.
With Ruijie's modular OS, the RG-SF2920 series switches support the simplistic optical Ethernet solution, and implement
lifecycle management, security control, plug and play, and intelligent O&M through software-defined networking (SDN).

Power Supply
RG-SF2920-16GT2MG2XS adopts an AC power supply, with the rated values as follows:
Rated voltage: 200–240 V~
Rated frequency: 50/60 Hz
Rated current: 0.6 A
Power cord requirements: 10 A power cord
Cooling
The RG-SF2920-16GT2MG2XS adopts natural cooling to ensure that the device works properly under specified
environment. When placing a chassis, maintain sufficient space for heat dissipation on both sides and above the chassis.
For details, see chapter 3 "Product Installation". Dust the device every three months to avoid blocking ventilation openings
on the housing.
