External Ports
The RG-S6120-48XS8CQ switch 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.
The RG-S6120-48XS8CQ switch supports 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.
SFP+ port: There are 48 10G SFP+ ports, which support optical modules and DAC copper cables, and are
compatible with 1000BASE-X.
QSFP28 port: There are eight 100G QSFP28 ports, which support 100G QSFP28 modules, 40G QSFP28
modules and DAC copper cables. The port can work in 4x25G mode.

Heat Dissipation
The working temperature of the RG-S6120-48XS8CQ 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-S6120-48XS8CQ 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-S6120-48XS8CQ supports M1EFAN II-F and provides fan speed regulation, fan failure warning, and fan hot
swapping.
Figure 1-2 Ventilation and Heat Dissipation of the RG-S6120-48XS8CQ
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.
Power modules and fan modules with different air direction cannot be used together.
