The product images involved in this manual are for indicative purpose only. The appearance is subject to the
actual equipment.
1.2 Component Modules
The RG-S6520-64CQ adopts the modular design. Compliant with industry standards, the design differentiates
modules and integrates module interfaces to ensure an integrated system with independent function modules.

Caution
Different power modules are interchangeable. That is, the switch allows concurrent AC and High-voltage DC
(HVDC) input. For example, input 1 uses mains electricity (AC power) and input 2 use Uninterrupted Power
Supply (UPS) HVDC power.
1.3 Chassis
The RG-S6520-64CQhardware system consists of a chassis, a power supply system, and a cooling system.
Power supply system: provides two power module slots and supports 1 + 1 power redundancy.

1.3.4 Cooling
The RG-S6520-64CQ adopts the front-to-rear airflow. Air flows in through the ports and out through the power
module, as shown in Figure 1-5.
Caution
Maintain a minimum clearance of 200 mm (7.87 in.) around the equipment for air circulation.

Hardware Installation and Reference Guide Overview

At least five fan modules are required. If any slot is unoccupied, install a filler panel to enable proper
airflow and to keep dust out of the chassis.
Dust the equipment every three months to avoid blocking the ventilation openings on the housing.

Warning
Operation of this equipment in a residential environment could cause radio interference.
This equipment is not suitable for use in locations where children are likely to be present.
This equipment should be installed in the equipment room. Only a skilled person should be allowed to
install, replace, or service this equipment. Do not open the enclosure when the equipment is running. Cut

1.4 Power Module
The smart power module for the RG-S6520-64CQ supports power consumption management and hot swapping.
It can obtain the output power, output current, and operating temperature in real time.
Caution
To improve system stability and availability, you are advised to configure 1 + 1 power redundancy. The
chassis configured with power redundancy works in current-sharing mode.
At least one power module is required. If any slot is unoccupied, install a filler panel to enable proper
airflow and to keep dust out of the chassis.
Unplug the power cord before installing or removing the power module.
