The asset management label is in the lower right corner of the rear panel. The label is movable and can be withdrawn

from the device. Users can mark the information such as asset name, category, code and registration date on the label

which helps to improve asset management accuracy and efficiency.

External Ports

The RG-S6920-4C provides the following ports:

Universal serial bus (USB) port: This port can connect with USB memory to save logs, host versions, warnings

and other diagnostic messages. Therefore, it is more convenient to upgrade the software version of the switch on

line and save the log information.

To protect the data and avoid device damage, use qualified USB flash disks of good brands. At the same time, the

local USB port is compatible with most of the USB controllers except some USB flash disks.

RG-S6920-4C series switches support debugging, configuration, maintenance, management and host software

uploading of Console ports.

Console port: Use RS-232 interface electrical level and standard RJ45 connector. This interface is connected with

the serial port of terminal PC to perform system debugging, configuration, maintenance, management, and host

software uploading.

MGMT port: This is an out-band Ethernet port, which uses standard RJ45 connector. This interface is connected

with Ethernet port of a PC to perform program downloading.

QSFP28 port: There are 8 100G QSFP28 ports, which support optical modules and DAC copper cables. These

ports can also work in 4x10G mode.

Power Supply

The RG-S6920-4C series switches support power supply the RG-PA1200I-F. The smart power supply module supports

power management, and the host can read input power, input current, and temperature in real time. The power supply

module supports hot swapping.

Hardware Installation and Reference Guide Product Overview

The RG-S6920-4C series switches support 2+2 power supply redundancy. To improve the stability and reliability

of the entire system, it is recommended to configure 2+2 power supply redundancy. When the four power supply

modules work normally, the switch is in the status of current sharing.

It requires at least two power supply modules to work normally. Filler panels need to be installed in the unoccupied

power supply module slots to ensure ventilation and heat dissipation and avoid dusts.

Heat Dissipation

The working temperature of the RG-S6920-4C switches is 0°C to 45°C (32°F to 113°F), and the heat dissipation design

needs to ensure the stability, safety and maintainability in such environment. The RG-S6920-4C series switches adopt

fan ventilation and forced convection to ensure the device can work normally in specified environment. Dust the device

every three months to avoid blocking the ventilation openings.

The RG-S6920-4C supports M2EFAN I-F and provides fan speed regulation, fan failure warning, and fan hot swapping.

Figure 1-5 Ventilation and Heat Dissipation of the RG-S6920-4C

Maintain a minimum clearance of 20 cm around the switch for ventilation.

It requires at least three fan modules to work normally. Filler panels need to be installed in the unoccupied fan

module slots to ensure ventilation and heat dissipation and avoid dusts.

The power module and fan module with different ventilation direction cannot be used together.
