1 Product Description
The RG-PF2920U-4GT1MS-P is the simplified optical Ethernet (SOE) switch released by Ruijie Networks for
all-optical network scenarios.
It can be used with the Power over Fiber (PoF) switch to realize remote power supply, dual-network deployment,
energy saving, and flexible installation. It is also designed with a built-in PD power supply, which is stable and
reliable and suitable for indoor scenarios.
With Ruijie's modular OS, the RG-PF2920U-4GT1MS-P is fit for the SOE solution, and implements lifecycle
management, security control, plug and play, and intelligent O&M through software-defined networking (SDN).

2 Preparing for Installation
2.1 Safety Precautions
Warning
To avoid personal injury and device damage, carefully read the safety precautions before you install the
RG-PF2920U-4GT1MS-P.
The following safety precautions may not cover all possible dangers.
2.1.1 Mounting
Keep the chassis clean and dust-free.
Do not place the device in a walking area.
During installation and maintenance, do not wear loose clothes, ornaments, or any other things that may be
hooked by the chassis.
Cut off all the power supplies and unplug all power cords before handling the switch.
2.1.2 Handling
Avoid handling the device frequently.
Keep balance and prevent personal injuries when handling the device.
Cut off all the power supplies and unplug all power cords before moving or handling the switch. Avoid scalds
because the housing surface is hot.
2.1.3 Electricity
Observe local regulations and specifications during electric operations. Only qualified personnel can perform
such operations.
Before installing the device, check whether there are hidden risks in the operating environment of the device.
For example, check whether the power socket is grounded and whether the ground is wet.
Determine the location of the indoor emergency power supply switch before installing the device. When an
accident occurs, immediately cut off all power supplies.
Do not maintain the device by yourself when the device is powered on.
Make sure that the device is powered off when you cut off the power supply.
Do not place the device in a wet position, and keep the device away from liquid.
Warning
Improper or incorrect electric operations may cause a fire, electric shock, and other accidents, and lead
to severe and fatal personal injury and device damage.
Direct or indirect contact through wet objects with high voltage or mains power supply may be fatal.
If a power supply system is equipped with a leakage protector (also referred to as leakage current switch
or breaker), the rated leakage action current of each leakage protector must be twice greater than the
maximum leakage current of all the power supplies in the system. For example, if the system is equipped
with 16 identical power modules and the leakage current of each power module is equal to or less than
