1 Overview
1.1 About the RG-S6250-48XS8CQ
The RG-S6250-48XS8CQ switch is a next-generation 10GE switch featuring high-
performance, high-density, and low-latency launched by Ruijie Networks for data centers and
high-end campuses. The RG-S6250-48XS8CQ switch provides high-density 10GE access,
100GE uplink ports, and diverse data center features. It can be used with Ruijie’s RG-N18000-
X and RG-S6920-4C switches for a high-performance and high-reliability data center network.

Caution
Different power modules are interchangeable. That is, the switch allows concurrentAC and DC
input. For example, input 1 uses mains electricity (AC power) and input 2 use Uninterrupted
Power Supply (UPS) DC power.
1.3 Chassis
The RG-S6250-48XS8CQ hardware 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.
Cooling system: provides four fan module slots and supports 3+1 fan redundancy.

1.3.4 Cooling
1. Overview
The RG-S6250-48XS8CQ 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 three 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.
