External Port
The CM88-CM module provides three external ports:
Universal Serial Bus (USB) port: By connecting to the USB port, the USB storage devices can store logs, host version,
alarms and other diagnosis information, facilitating online upgrade of switch software and storage of logs.
To secure data and prevent damage to the device, it is recommended to use high-quality flash disks produced by
reliable manufacturers. The USB port is compatible with most USB controllers but may be unable to identify some
USB disk models.
Console port: As a serial communications port, it uses the RS-232 interface level and standard RJ-45 connector. This
port is used to connect the device to serial ports of background terminal computers to perform tasks including system
commissioning, configuration, maintenance, management, and host software loading.
10/100/1000M MGMT port: As the 10/100/1000BASE-T Ethernet port, it uses the RJ-45 connector. This port can be
used to connect the device to the Ethernet port of the background computer to load programs. Use the standard cable
to connect the device to the Ethernet port of the background computer.
Button
The CM88-CM module provides a FUNC button, which is used to reset the system. If the button is held for less than five
seconds, it is a short press; if the button is held for five seconds or longer, it is a long press.
In case of a short press, the Status LED flashes in green, and the device resets within five seconds after the press.
In case of a long press, the Status LED flashes in green and then flashes in red; the device resets within five seconds
after the press.
Press the button, and the system starts to collect information, during which the device will not restart. After the

Avoid moving the equipment frequently.
Turn off all power supplies and unplug all power cables before you remove the equipment.
At least four people are needed to move the equipment. Do not attempt to move the equipment by one people only.
Keep balance when moving the equipment, and avoid injuring your leg and feet or spraining your waist.
Do not move the equipment by grasping the panel, power supply handle, ventilation holes of the chassis, as they are
not designed to bear the weight of the entire equipment. This may cause damage or even injure you.
Remove all supervisor modules, service modules and power modules before you move the device, to reduce the
chassis weight.
The device must be installed and used in the restricted access location.
3.1.3 Electrical Safety
Please observe local regulations and specifications when performing electrical operations. Relevant operators must
be qualified.
Please carefully check for any potential danger in the working area, for example, ungrounded power supply, unreliable
grounding of the power supply and damp/wet ground or floor.
Find out the location of the emergency power supply switch in the room before installation. First cut off the power
supply in case of an accident.
Be sure to make a careful check before you shut down the power supply.
Do not place the equipment in a damp/wet location. Do not let any liquid enter the chassis
Any nonstandard and inaccurate electrical operation can cause an accident such as fire or electrical attack, thus
causing severe even fatal damages to human bodies and equipment.

Direct or indirect touch through a wet object on high-voltage and mains supply can bring a fatal danger.
3.1.4 Static Discharge Damage Prevention
Although much has been done in RG-CS88-08 to prevent static electricity, great damage may be caused to the circuitry
and equipment when the static electricity exceeds a certain limit. In the communication network of the RG-CS88-08,
electrostatic induction may come from the following sources: External electric field produced by the high-voltage supply
cable, lightning, etc; internal systems such as the indoor floor and the entire structure.
To prevent damage from static electricity, you must pay attention to the following:
Properly ground the equipment.
Take dust prevention measures in the room.
Maintain an appropriate humidity.
Always wear an anti-static wrist strap when you touch any circuit board.
Try to hold a circuit board by its edges. Do not touch any components or the PCB.
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.
The CS88-08 series switches are equipped with an anti-static wrist strap. Please refer to Figure 2-1 for the position
of the jack for the wrist strap.
The CS88-08 series switches are equipped with an anti-static wrist strap. To protect electronic components against static
electricity, wear an anti-static wrist strap close to your skin and keep it properly grounded while installing swappable
modules.
Use an anti-static wrist strap as follows:
Ensure that the switch is properly grounded.
Put your hand in the anti-static wrist strap.
Tighten the buckle till the trap is closely attached to your skin.
For safety, use a multimeter to measure the resistance between yourself and the ground, which should be within the
range from 1 to 10 Ω.
Make sure that the switch is properly grounded when the anti-static wrist strap is connected to the ground through
the chassis jack.

Precautions:
When a fiber transceiver works, ensure that the port has been connected with a fiber or is covered with a dust cap so
as to keep out dust and avoid burning your eyes.
Do not stare into any fiber port.
Do not stare into any fiber port under any circumstances, as this may cause permanent damage to your eyes.
3.2 Installation Site Requirements
RG-CS88-08 must be used in the room. To ensure normal operation and a prolonged useful life of the equipment, the
installation site must meet the following requirements.
3.2.1 Load Bearing Requirements
Evaluate the load bearing requirements for the ground according to the weight of the switch and its components (such as
the cabinet, chassis, single board and power supply). Make sure the installation site meet the requirements.
3.2.2 Space Requirements
It is recommended that the width of the machine room corridor be greater than 0.8m to ensure enough space for
moving of chassis and plugging and removing of modules.
Please do not install the switch against the wall. Instead, please leave some space around the switch for heat
dissipation and switch maintenance.
3.2.3 Ventilation Requirements
See Product Overview for heat dissipation and ventilation. Maintain a minimum clearance of 10 cm around the air intakes
and exhaust vents for ventilation. After connecting various cables, you should bundle the cables or place them in the cable
management bracket to avoid blocking air intakes.
Remove all foam packaging materials and protective plastics before you power on the switch.
3.2.4 Temperature Requirements
To ensure the normal operation and a prolonged useful life of the RG-CS88-08, you must maintain an appropriate
temperature in the equipment room. Too high or low temperature for a long period of time may damage the equipment.
In an environment with high temperature, the equipment is subjected to even greater harm, as its performance may
degrade significantly and its useful life may be shortened in the case of long-term exposure that expedites the aging
process.
