External Ports
The RG-S6250-48XS8CQ 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-S6250-48XS8CQ 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.
SFP+ port: There are 48 10G SFP+ ports, which support optical modules and DAC copper cables (1000BASE-X
compatible).
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-S6250-48XS8CQ series switches support power supply the RG-PA550I-F and RG-PA550I-R. 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.
The RG-S6250-48XS8CQ series switches support 1+1 power supply redundancy. To improve the stability and
reliability of the entire system, it is recommended to configure 1+1 power supply redundancy. When the two power
supply modules work normally, the switch is in the status of current sharing.
It requires at least one power supply module 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-S6250-48XS8CQ switches is 0°C to 45°C, or 32°F to 113°F, and the heat
dissipation design needs to ensure the stability, safety and maintainability in such environment. The
RG-S6250-48XS8CQ 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-S6250-48XS8CQ supports M1EFAN II-F and M1EFAN II-R and provides fan speed regulation, fan failure
warning, and fan hot swapping.

Leave sufficient space in the front and at the back of the chassis (at least 20 cm) 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.
2 Preparation before Installation
2.1 Safety Precautions
To avoid body injury and device damage, please carefully read the safety precautions before you install the RG-
S6250.
The following safety precautions do not cover all possible dangers.
2.1.1 Installation Safety
Keep the chassis clean and dust-free.
Do not place the device in walking areas.
Do not wear loose clothes, ornaments or any other things that may be hooked by the chassis during the
installation and maintenance.
Turn off all power supplies and unplug all power cords and cables before the installation or the dismantling.
2.1.2 Removal Safety
Avoid frequent removals after the device is installed.
Turn off all power supplies and unplug all power cords and cables before the installation or the dismantling.
When removing the device, pay attention to the balance and avoid hurting legs and feet or straining the back.

- 8 -
When the device is being removed, do not hold the power supply handle or the fan handle for these parts are not
designed for bearing the entire weight of the device. It will cause damage to the device or to your body if you hold
these parts when removing the device.
To reduce the weight of the chassis during the removal, dismantle the extension module, fan module and the
power supply module first.
Install and operate the device in places where removing is restricted.
2.1.3 Electric Safety
Observe local regulations and specifications when electric operations are performed. Relevant operators must be
qualified.
Carefully check any potential danger in the working area, such as ungrounded power supply, unreliable grounding
of the power supply, and damp/wet ground.
Find out the location of the emergency power supply switch in the room before installation. First cut off the power
supply in the case of an accident.
Be sure to make a careful check before you shut down the power supply.
Do not place the device in a damp location. Do not let any liquid enter the chassis.
Any nonstandard and inaccurate electrical operation can cause accidents such as fires or electrical attacks, thus
causing severe, or even fatal damages to human bodies and the devices.
Direct or indirect touch through a wet object on high-voltage and mains supply can bring a fatal danger.
2.1.4 Electrostatic Discharge Damage Precautions
The RG-S6250-48XS8CQ designing gives a great consideration to prevent electrostatic discharge damage and adopts
multiple measures. But if the electrostatic exceeds certain limit, it can still cause great damages to the circuitry and the
device. In networks connected by the RG-S6250-48XS8CQ, the major sources of electrostatic induction are outdoor
high voltage transmission cables, lightening, indoor floor materials and the machine structure.
Pay attention to the following tips:
The device and the floor are well grounded.
Take dust prevention measures in the room.
Maintain an appropriate humidity.
When the pluggable modules of the switch are being installed, wear antistatic wrist strap and make sure the
antistatic wrist strap is well grounded.
Do not use bare hand to directly touch the components and the printed-circuit board (PCB) when the boards are
used.
Use an anti-static shielding bag to properly store the board.
Do not let any clothes touch a circuit board. An antistatic wrist strap can only prevent human static electricity from
damaging the circuit board, but cannot prevent any static electricity on clothes.
