1 Overview
1.1 About the RG-S6930-2C
The RG-S6930-2C switch is a core switch featuring high-performance, high-density, and large-buffer launched
by Ruijie Networks for data centers and high-end campuses. The RG-S6930-2C switch adopts a flexible
modular design with 100GE/200GE expansion modules and diverse data center features, which can be
deployed as the data center gateway for MAN and DCI scenarios. It can be used with Ruijie’s RG-N18000-X
and RG-S6500 switches for a high-performance and high-reliability data center network.

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.
Different expansion modules are not interchangeable.
1.3 Chassis
The RG-S6930-2C hardware system consists of a chassis, a power supply system, and a cooling system.
Power supply system: provides four power module slots and supports 2+2 power redundancy.
Cooling system: provides eight fan module slots and supports 7+1 fan redundancy.
Expansion module: provides two expansion module slots and supports two models.

1.3.4 Cooling
The S6930-2C 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.
At least seven 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.
