RG-CS88-08 switch is a class A product. In a domestic environment, this product may cause radio interference in
which case the user may be required to take adequate measures.
Product Appearance
The hardware system of the RG-CS88-08 switch is composed of the chassis, the power system, modules and the cooling
system.
The power system provides four power supply slots and supports N+N power redundancy.
The RG-CS88-08 switch provides two supervisor module slots and six service module slots. The supervisor modules
support 1+1 redundancy. Users are recommended to configure redundancy for the supervisor modules. Users may
choose different service modules as needed.

Power supply
The RG-CS88-08 switch adopts both AC power supply input.
AC power supply input: The RG-PA1600I-F and the RG-PA600I-F power supply modules are supported. The two
types of power supply modules support power management. The supervisor module of the RG-CS88-08 switch can
read the power supply information and implement flexible and intelligent power management.
The RG-CS88-08 switch supports N+N power supply redundancy to improve the system stability and reliability. We
recommend users to configure N+M redundancy for power supply modules.
Heat Dissipation System
The operating environment temperature of the RG-CS88-08 switch ranges between 0 and 50°C . The thermal design must
satisfy the requirement on the device's reliability in the temperature range while ensuring the device's safety and
maintainability. According to the thermal design of the RG-CS88-08 switch, fans are used to draw air for forced convection
cooling in order to ensure that the device works properly in the specified environment.

modules
3. Exhaust vents for system power modules
For the PoE power supply modules, air flows across the chassis from the back intakes to the front vents.
For the supervisor and service modules, air flows across the chassis from the right intakes to the back vents.
For the power supply modules, air flows in from the front intakes and out from the back vents.
The chassis should be mounted in a place with sufficient space for air circulation. Maintain a minimum clearance of
10cm around the chassis.

If any module slot is unoccupied, install a filler panel to ensure proper airflow.
2 Module
The RG-CS88-08 switch adopts the module-based design. Compliant with industry standards, the design divides modules
and integrates module interfaces to ensure the switch system's functioning and independence of various function modules.
The modules of the RG-CS88-08 switch provide 10/100/1000M auto-sensing Ethernet copper ports, 1000 Mbps/100 Mbps
SFP (single-mode/multi-mode) optical fiber interfaces and 10G/40G optical fiber interfaces.

CM88-CM is the supervisor module of the RG-CS88-08 series switches and is designed with management and switching
functions.

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
collection is complete, the device restarts automatically. Hold the button for a while and release it, the device restarts
automatically in five seconds.
